Discover how Scripture, the larger story of redemption, and your identity in Christ can help you see clearly today—before regret teaches you tomorrow.

This episode is part of a nine-part series on commissions. How to prepare for them, respond to them, deliver them, and, crucially, how to stop them burning you out. If you haven't followed the podcast yet, hit follow so you don't miss an episode. Today, episode four of nine. And this is where the series shifts gears. For the last three episodes, we have been doing the preparation work. The mindset. The five signatures of under-pricing. The commission ecosystem. Today, an enquiry has arrived. This is the moment most artists get wrong because this is the moment their nervous system takes over. When an enquiry lands in your inbox. And before you've finished reading it, your stomach has tightened, your brain is already drafting a reply, and somewhere in the next three sentences you're going to offer availability, ideas, enthusiasm, and a half-committed yes – all before you know you are a good fit. And the principle is this. Before you reply with anything, you filter. How, is what today´s episode is about. KEY TAKEAWAYS Ceri´s short enquiry form is a low-friction sieve: it quietly filters out tire-kickers, and a serious client will fill it in within 10 minutes. The right questions reveal what they actually want, how committed they are, whether they really get your work, and whether their budget and timeline are realistic. After the enquiry form, you move into a chemistry call – 30 minutes - to ask important questions and spot red flags. Then, produce an alignment document to further test understanding. If the client confirms the alignment document, you move forward; if they come back with big changes, it's a sign you weren't fully aligned on the call – it's far better to catch that now than 3 months into making. BEST MOMENTS “Stage one of responding to any inquiry is the initial filter, low friction, high signal, a sieve, not a conversation.” “If those signals are weak, you slow things down, you don't ghost them, but you don't rescue them, you reply politely with more questions,” “The alignment document - a short-written document that confirms in writing what you heard, not a proposal, not a quote, an alignment document.” For a text version of today's teaching, plus new practical guidance every week, you can subscribe to Beat the Block at http://cerihand.com/subscribe EPISODE RESOURCES First episode of this 9-part series - https://podcasts.apple.com/gb/podcast/designing-the-way-you-want-to-work-the-mindset/id1709105337?i=1000769915059 HOST BIO With over 35 years in the art world, Ceri has worked closely with leading artists and arts professionals, managed public and private galleries and charities, and curated more than 250 exhibitions and events.

Are you taking business advice from people who don't actually know you, your goals, or where you're trying to go? In this episode of Business Your Way, Caryn breaks down one of the most important — and overlooked — jobs you have as a business owner: protecting your business your way.Caryn covers why well-meaning advice from even successful entrepreneurs can send you in the completely wrong direction, how to recognize when you're consuming 7-figure advice that doesn't apply to your 5- or 6-figure business, and why discernment is the skill that separates coaches who stay stuck from those who build sustainable, profitable businesses.You'll also hear why always knowing what you're selling is one of the most protective things you can do for your business, and how to use your values and financial goals as filters to cut through 90% of the noise online.If you're a life coach or small business owner tired of buying random courses, second-guessing your strategy, or feeling pulled in every direction, this episode is your reminder to return to yourself and protect your mission.Topics covered:Why not all advice is created equal — even from people who've "made it"The danger of learning ahead of where you are in businessTreating your business like a newborn (and what that means practically)Always selling: why cash is the ultimate business protectorHow to develop discernment so you stop buying things you don't needUsing your values to filter out tactics that won't work FOR YOU

Filter problems love to disguise themselves as “chemistry issues” and that's exactly how pool owners waste weekends and pool pros lose hours. We walk through the real decision that matters: do you simply need new filter media, or is it time to replace the whole filter body because the tank, clamp, or lid is worn out and headed toward failure.We start with the basics in plain language: what “filter media” means for cartridge, DE, and sand systems, and why each has a different lifespan. Then we get practical with sand filters, including the signs that sand is no longer doing its job (weekly backwashing, rising pressure, poor flow, and water that never quite looks right). If you're debating a pool filter upgrade, we talk through when a cartridge filter makes sense, when a sand filter is still the better choice in heavy dirt regions, and why large square-foot cartridge filters can deliver better circulation and more consistent filtration.We also share the real-world replacement schedule that keeps service routes smooth: the three-year strategy for quad cartridges and DE grids, what happens when grids tear and DE leaks back into the pool, and the important exceptions where cost and build quality justify longer intervals. Finally, we cover when replacing the entire filter is the smart move, plus what changes when converting from DE to cartridge (including plumbing considerations and removing backwash hardware).If you want fewer surprises, cleaner water, and better flow, subscribe, share this with a pool owner or pool tech, and leave a review with the filter type you're running and the problems you're seeing.We break down how to decide between replacing pool filter media and replacing the entire filter, using real service-route triggers like pressure rise, flow loss, and stubborn water clarity issues. We also lay out practical upgrade paths from sand or DE to cartridge so you can reduce mess, improve circulation, and prevent mid-season failures.  • defining filter media across cartridge, DE and sand systems  • diagnosing sand filter performance using clarity, flow and backwash frequency  • weighing sand filter simplicity against water waste and lower filtration  • why large cartridge filters often outperform sand in everyday use  • setting a proactive replacement schedule for cartridges and DE grids  • spotting grid tears and deciding when to replace one grid vs all  • handling expensive cartridge exceptions and extending lifespan responsibly  • deciding when an aging filter tank should be replaced for safety and cost  • planning plumbing changes when converting DE to cartridge  Are you a pool service pro looking to take your business to the next level?

Martha asks, “Am I doing the right thing?” The Corinthians asked, “Is this allowed?” Paul asks a different question entirely, “What kind of person and community are we becoming?” He wants us to use a new filter: Does it build up? Does it give life?  Does it deepen love in Christ? We live in a world that is constantly competing for our attention, but the deepest question is not what captures our attention—it is what deserves it. Increasingly, what keeps us from the life of Christ himself – that resurrected, powerful life filled with the Spirit – isn't the BAD stuff. It's filters. Distractions. The world is eager to tell us where fullness can be found. More achievement. More consumption. More visibility. More urgency. More power.  More of whatever keeps us moving fast enough that we never stop long enough to ask whether we're becoming wise. When all the while, the call of Jesus is simply to sit and be.  The work will come in due time.

Wie du im Selfpublishing erfolgreich mit Dienstleistern und Dienstleisterinnen zusammenarbeitest In dieser Folge spreche ich über ein zentrales Thema im Selfpublishing: die Zusammenarbeit mit Dienstleister:innen. Ob große Konzerne wie Amazon und BOD oder individuelle Profis wie Coverdesignerinnen, Lektoren und Buchsetzerinnen – die Art der Kommunikation und die Qualität der Zusammenarbeit sind entscheidend für den Erfolg deines Buchprojekts. Ich teile meine Erfahrungen aus über 15 Jahren in der Buchbranche und zeige dir, worauf du achten solltest, wie du Missverständnisse vermeidest und mit welchen Strategien du das Beste aus der Zusammenarbeit herausholst. Außerdem erfährst du, warum klare Abmachungen, Vertragsdetails und Respekt im Umgang miteinander so wichtig sind – und wie du langfristige, vertrauensvolle Beziehungen aufbauen kannst. Ob du gerade erst startest oder schon mehrere Bücher veröffentlicht hast: ‚Auch diese Folge bietet dir wertvolle Tipps und Impulse für deinen eigenen Weg im Selfpublishing!   Hier die wichtigsten Aspekte, die ich in dieser Folge anspreche: # Die 10 wichtigsten Erkenntnisse aus der Folge   1. Zwei Hauptgruppen von Dienstleistern  Die Zusammenarbeit im Selfpublishing unterscheidet sich stark zwischen großen Firmen (wie Amazon, BOD, Tolino) und Einzeldienstleister:innen (z.B. Coverdesigner:innen, Lektor:innen). Diese beiden Gruppen erfordern jeweils unterschiedliche Kommunikationsstrategien.   2. Großunternehmen sind nicht für Autor:innen da, sondern für den eigenen Profit  Eine zentrale Erkenntnis ist, dass große Unternehmen wie Amazon & Co. primär auf Gewinn ausgerichtet sind und nicht existieren, um Autor:innen zu helfen, ihre Bücher zu veröffentlichen.   3. Kommunikation verläuft oft über Filter und Automatisierungen  Der Kontakt mit Großunternehmen verläuft meist unpersönlich und automatisiert. Persönlicher Kontakt findet nur selten statt – und selbst dann sind die Mitarbeitenden an Vorgaben gebunden.   4. Respekt und Freundlichkeit sind grundlegend  Ich kann es nicht oft genug wiederholen, sowohl im Umgang mit Großunternehmen als auch Einzeldienstleister:innen lohnt es sich stets respektvoll und freundlich zu bleiben, aber dabei auch bestimmte Anliegen klar und bestimmt zu äußern.   5. Kommunikation und Austausch mit Kolleg:innen ist wertvoll  Der Austausch mit anderen Selfpublisher:innen hilft, gemeinsame Probleme zu erkennen und Lösungsansätze zu finden. Oft treten dieselben Schwierigkeiten bei mehreren gleichzeitig auf.   6. Geduld und Vorbereitung sind wichtig  Gerade bei großen Firmen muss mit längeren Wartezeiten gerechnet werden. Es ist hilfreich, sich vor Anfragen bereits in den Hilfetexten und Angeboten zu informieren, um gezielt nachfragen zu können.   7. Vertragsprüfung ist unerlässlich  Du musst die Vertragsbedingungen und AGBs der Dienstleister:innen unbedingt genau lesen, insbesondere was Rechte, Exklusivität und nicht beabsichtigte Klauseln (z.B. Hörbuchrechte) betrifft.   8. Schriftliche Abmachungen mit Einzeldienstleister:innen sind essenziell  Für alle Leistungen – vom Coverdesign bis zum Lektorat – brauchst du klare, schriftliche Abmachungen darüber, was geleistet wird und wie die Bezahlung geregelt ist, um Missverständnisse zu vermeiden.   9. Präzises Briefing ist erfolgsentscheidend  Je genauer und spezifischer die eigenen Vorstellungen an Dienstleister:innen kommuniziert werden, desto besser werden die Ergebnisse. Unklare Angaben führen zu schlechten Resultaten und langwierigen Prozessen.   10. Klare Absprachen zu Kommunikation und Bezahlung schaffen Sicherheit  Vereinbarungen über Kommunikationswege und Zahlungsmodalitäten sollen von Anfang an geklärt werden. Auch Authentizität, Ehrlichkeit und Verlässlichkeit in der Zusammenarbeit sind Schlüssel für langfristig erfolgreiche Beziehungen.   Zusammenarbeit mit Dienstleister:innen im Selfpublishing – Warum, wie und worauf du achten solltest Wenn du dein Buch im Selfpublishing veröffentlichen willst, kommst du nicht drum herum: Du musst mit Dienstleister:innen zusammenarbeiten. Das klingt erstmal stressig, kann aber richtig Spaß machen – wenn du ein paar Dinge beachtest. In Folge 334 vom Mission Bestseller Podcast dreht sich alles um das Thema: Wie läuft die Zusammenarbeit mit Dienstleister:innen ab? Welche Fettnäpfchen kannst du vermeiden? Und wie sorgst du dafür, dass dein Buch-Projekt nicht zur Katastrophe wird? Hier bekommst du den Überblick – locker-flockig und mit einem Augenzwinkern. Zwei Sorten Dienstleister:innen – und warum das wichtig ist In der Selfpublishing-Welt unterscheiden sich grob zwischen zwei Arten von Dienstleister:innen: die großen Konzerne (Amazon, BOD, Tolino, Nova MD etc.) und die Einzeldienstleister:innen wie Cover-Designer:innen, Lektor:innen oder Buchsetzer:innen. Und ganz ehrlich: Der Unterschied könnte größer nicht sein! Die großen Firmen sind deine Eintrittskarte in den Buchmarkt. Ohne sie läuft nichts - sie drucken, distribuierten, listen und liefern deine Buchbabys aus. Aber Achtung: Die machen das nicht für dein Wohl, sondern für den Profit. Liebe Autor:in, falls du dachtest, Amazon und Co. existieren nur, um deinen Traum vom Bestseller zu realisieren – sorry, da muss ich die Seifenblase platzen lassen. Sie wollen Geld verdienen, und zwar so viel wie möglich. Respekt und Professionalität – auch bei den Großen Was heißt das für die Zusammenarbeit? Erstmal: Bleib freundlich! Die Menschen (und Bots), die dir bei den großen Dienstleister:innen begegnen, hängen auch nur in ihrem Arbeitskorsett und können nicht zaubern. Aufregen bringt nix, Respekt hingegen kommt immer gut an. Kommunikation ist das A und O – und manchmal leider auch ein Geduldsspiel. Mach dir klar: Die Wartezeiten können lang werden, gerade bei BOD oder Nova MD. Amazon antwortet zwar schnell, aber meistens bekommst du erstmal Standardantworten à la FAQ-Bot 3000. Da hilft: Sich mit anderen Autor:innen austauschen, nachfragen, ob dein Problem ein Einzelfall ist oder ob gleich eine ganze Meute betroffen ist. So fühlst du dich weniger allein und kommst eventuell schneller voran. Ganz, ganz wichtig: Lies dir die Vertragsbedingungen durch! Und ja, ich weiß, das ist so spannend wie Steuererklärung, aber du willst nicht plötzlich alle Hörbuchrechte bei einem Dienstleister eingebucht wissen, nur weil du aus Versehen ein Häkchen falsch gesetzt hast. Die Einzeldienstleister:innen – Lektorat, Cover, und Co. Kommen wir zum zweiten Team in deinem Autor:innen-Leben: die Einzelkämpfer:innen, die sich liebevoll um deinen Text, dein Cover oder das Korrektorat kümmern. Hier ist der Umgang oft persönlicher – aber gerade deshalb sollte alles Schwarz auf Weiß geregelt sein. Verträge schützen beide Seiten. Das klingt nach Anwalt und Stress, ist aber oft das, was am Ende Freundschaften rettet. Wer übernimmt was, zu welchem Preis und in welcher Frist? Das klärst du unbedingt schriftlich. Und wenn dir jemand für ein Komplett-Korrektorat 50 Euro anbietet, dann investiere das Geld lieber in einen Espresso und nutze eine Textmaschine – Ernsthaftigkeit sieht anders aus. Gute Arbeit hat ihren Preis, und das ist auch sinnvoll, schließlich möchtest du, dass die Leute von ihrer Arbeit leben können. Sei ehrlich zu dir selbst: Was ist dir dein Buch wert? Ein gutes Cover ist kein Fiverr-Schnäppchen und ein ordentliches Lektorat kostet Zeit und Geld. Klar kommunizieren – macht alles leichter Egal, ob Cover-Design oder Buchsatz: Je klarer du beschreibst, was du willst, desto glücklicher sind am Ende alle. Vage Angaben führen nur zu Frust und endlosen Korrekturrunden. Rot und Gelb sind für dich vielleicht Farben, für Grafiker:innen aber ein ganzes Universum. Je genauer dein Briefing, desto besser das Ergebnis! Und wenn mal etwas nicht passt – sei ehrlich. Freundlich, aber ehrlich. Nur so kommt ihr gemeinsam ans Ziel. Sprich auch Kommunikationskanäle ab. Wenn du nur E-Mail magst, sag es. Wenn du WhatsApp nicht ausstehen kannst, dann sag's auch. Das erspart vielen Beteiligten das große: „Wie war nochmal der letzte Stand?" Und zu guter Letzt: Bleib flexibel. Nicht jedes Dienstleister:innen-Abenteuer wird ein Match made in Heaven. Jede:r hat schon die eine oder andere Enttäuschung erlebt – das gehört dazu. Offenheit, Respekt und die Bereitschaft, aus Fehlern zu lernen, bringen dich immer weiter. Das Miteinander macht den Unterschied Selfpublishing ist Teamarbeit. Du hast die Kontrolle, klar – aber ohne gute Zusammenarbeit mit Dienstleister:innen wird's schnell ein einsames, frustiges Unterfangen. Also: Verträge machen, respektvoll (und mit einer Prise Humor) kommunizieren, Budgets realistisch kalkulieren – und immer wieder mit anderen austauschen. So wird dein Buchprojekt nicht nur erfolgreich, sondern auch angenehm für alle, die an ihm mitarbeiten. Und falls du doch mal mit eine:r Dienstleister:in streitest – denk daran: Jede Anekdote ist potenzieller Stoff für dein nächstes Kapitel.

This month we return to our lesbian dating and relationship conversation, the one we share on the second Friday of every month, and by popular request Tonda is back at the table! Anne-Marie is joined by her wife, Tonda McKay, our longtime out lesbian and resident truth teller, and by Barbara Rowlandson, fellow coach and the woman who helps lead our Authentically Us community. Together we work through four real questions pulled from the Lesbian Dating Advice subreddit, and the conversation moves from laughing out loud to genuinely tender.We start with the question so many of us know by heart, is my barista flirting with me, and we talk about strategic ambiguity, the cognitive itch that turns a maybe into a crush, and why two women who like each other can sit in a room and say nothing at all. From there we look at a girlfriend whose closest bond is with her straight married best friend, and we ask the harder question underneath the jealousy, are your needs being met in this relationship. We sit with a heartbreaking note from someone whose partner ended things out of religious guilt, and Anne-Marie and Tonda speak plainly about internalized shame, the cost of loving someone who is still in the closet, and the truth that you can be both gay and beloved by the Divine. We close with the "break" at seven months that is really a breakup, the anxious and avoidant dance, and Barbara's reminder that if someone tells you that you are too much, you are free to go find less.A few invitations from this episode. If you are wrestling with the clobber passages and the old messages about faith and sexuality, we point you toward the resources at Cathedral of Hope in Dallas, a UCC congregation that does this work with real care: https://www.cathedralofhope.com/If this season of your life has a catalyst of its own, Barbara and Anne-Marie created The Catalyst Chapter, a course to help you understand why this work can feel so hard and so holy, and you can find it inside Authentically Us and on the Anne-Marie Zanzal Coaching website, https://annemariezanzal.com/We taped this on the first of June, so wherever you are, we hope you find your way to some community and some queer joy this Pride month, and if it is safe and right for you, we hope you let yourself be seen. We are so glad you are here!

Du postest, netzwerkst, verbesserst deine Website, und dennoch bleibt der Umsatz hinter deinen Erwartungen? Dann könnte der Grund tiefer liegen, als du denkst. Nicht in deiner Strategie. Sondern in deinem Kopf. In diesem Artikel zeige ich dir, was Silent Subliminals sind, wie sie wirken – und warum sie dir dabei helfen können, Kunden anzuziehen, anstatt ihnen hinterherzulaufen. Kein Hype, keine Versprechen ohne Grundlage. Aber ein ehrlicher Blick auf ein Werkzeug, das immer mehr Selbstständige und Unternehmer:innen in ihren Alltag integrieren. Warum Kunden anziehen kein reines Marketing-Problem ist Lass uns kurz ehrlich sein: Die meisten Business-Probleme, die sich nach „schlechtem Marketing" anfühlen, sind in Wirklichkeit Mindset-Probleme. Du glaubst vielleicht insgeheim, dass du zu wenig Erfahrung hast. Dass dein Angebot nicht gut genug ist. Dass andere Anbieter:innen einfach besser sind. Dass Geld verdienen kompliziert sein muss. Oder dass du „so jemand" nicht bist, der leicht Kunden gewinnt. Diese Überzeugungen sitzen nicht in deiner Marketingstrategie. Sie sitzen in deinem Unterbewusstsein. Und das Tückische daran: Du merkst es oft gar nicht. Das Unterbewusstsein arbeitet leise im Hintergrund – es filtert, wie du Chancen wahrnimmst, wie du auf potenzielle Kunden zugehen, wie du kommunizierst, und wie viel du dir selbst erlaubst, zu verdienen. Genau hier kommen Silent Subliminals ins Spiel. Was sind Silent Subliminals? Eine verständliche Erklärung für Einsteiger Silent Subliminals sind Audiodateien, die positive Affirmationen enthalten – allerdings auf einer Frequenz, die außerhalb des bewussten Hörvermögens liegt. Der Begriff „silent" ist dabei etwas irreführend: Die Aufnahmen sind nicht vollständig stumm. Stattdessen werden die gesprochenen Affirmationen auf eine sehr hohe Frequenz (typischerweise um 14.000–17.000 Hz) moduliert. Du hörst sie nicht bewusst als Sprache – aber dein Gehirn soll sie dennoch verarbeiten. Ergänzt werden viele Silent Subliminals mit entspannender Hintergrundmusik, zum Beispiel 432-Hz-Musik, die eine harmonisierende Wirkung auf das Nervensystem haben soll. So klingen die Aufnahmen für dich wie ruhige Ambient-Musik oder Naturklänge – während im Hintergrund zielgerichtete Botschaften für dein Unterbewusstsein eingebettet sind. Was steht dahinter? Die Theorie hinter Silent Subliminals stammt aus der Forschung zu subliminaler Wahrnehmung und auditiver Verarbeitung. Die Idee: Weil die Affirmationen nicht bewusst wahrgenommen werden, umgehen sie den sogenannten „kritischen Filter" des Bewusstseins – also den Teil deines Geistes, der neue Informationen sofort bewertet und oft ablehnt. So sollen positive Überzeugungen direkter im Unterbewusstsein verankert werden. Wichtiger Hinweis: Die wissenschaftliche Forschung zu Silent Subliminals steckt noch in den Kinderschuhen. Es gibt erste Hinweise auf Wirksamkeit subliminaler Audiostimulation, aber keine abschließenden klinischen Beweise. Silent Subliminals sind kein Ersatz für professionelle Beratung, Therapie oder solides Business-Know-how. Sie sind ein ergänzendes Werkzeug – und als solches solltest du sie einsetzen. Wie Silent Subliminals wirken – der Mechanismus dahinter Um zu verstehen, wie Silent Subliminals beim Kunden anziehen helfen können, lohnt sich ein kurzer Blick auf das Zusammenspiel von Bewusstsein und Unterbewusstsein. Dein Bewusstsein trifft Entscheidungen. Dein Unterbewusstsein setzt sie um – oder sabotiert sie. Es arbeitet auf Basis von Glaubenssätzen, die sich über Jahre, manchmal Jahrzehnte, eingraviert haben. Manche davon sind hilfreich. Viele davon – besonders rund um Geld, Erfolg und Selbstwert – nicht. Das klassische Problem bei Affirmationen, die du laut sprichst oder schreibst: Dein Bewusstsein hört zu und zweifelt sofort. Du sagst „Ich ziehe leicht Kunden an" – und eine innere Stimme antwortet prompt: „Aha. Sicher." Silent Subliminals sollen dieses Problem umgehen. Weil du die Affirmationen nicht bewusst wahrnimmst, findet keine direkte Ablehnung statt. Die Botschaft soll tiefer ankern können. In der Praxis nutzen viele Menschen Silent Subliminals so: Beim Schlafen – im Hintergrund laufen lassen, während du schläfst Beim Frühstück oder Duschen – als Teil der Morgenroutine Beim Arbeiten – leise im Hintergrund, ohne den Fokus zu stören Beim Sport oder Spazierengehen – als motivierender Begleiter Der entscheidende Vorteil: Du musst keine zusätzliche Zeit investieren. Silent Subliminals laufen parallel zu deinem Alltag. Die Verbindung zwischen Mindset und Kundengewinnung Warum spielt das Mindset überhaupt eine Rolle, wenn es ums Kunden anziehen geht? Ganz einfach: Kunden kaufen Menschen. Und Menschen erspüren, wie jemand zu sich selbst und zu seinem Angebot steht – auch wenn sie das nicht in Worte fassen können. Ein Verkaufsgespräch mit jemandem, der innerlich überzeugt ist, einen echten Wert zu liefern, fühlt sich anders an als eines mit jemandem, der im Stillen hofft, nicht abgelehnt zu werden. Das zeigt sich in: Deiner Preisstrategie – Verlangst du, was dein Angebot wert ist? Oder gibst du schnell nach? Deiner Sichtbarkeit – Trittst du selbstbewusst auf, oder versteckst du dich hinter Perfektionismus? Deiner Kommunikation – Sprichst du klar darüber, was du tust und für wen? Oder bist du vage, um niemanden abzuschrecken? Deiner Ausdauer – Gibst du bei ersten Rückschlägen auf? Oder bleibst du dran? All das sind keine Marketing-Techniken. Das ist Haltung. Und Haltung entsteht im Kopf – genauer gesagt: im Unterbewusstsein. Wenn Silent Subliminals helfen, hinderliche Glaubenssätze durch förderliche zu ersetzen, arbeiten sie damit an der Wurzel vieler Business-Herausforderungen. Typische Blockaden, die Selbstständige beim Kunden anziehen bremsen Bevor wir zu den konkreten Tipps kommen: Erkennst du dich in einem dieser Muster wieder? 1. Das Hochstapler-Syndrom Du zweifelst innerlich, ob du gut genug bist – obwohl deine Kunden zufrieden sind. Du zögerst, dich klar zu positionieren, weil du Angst hast, aufzufliegen. 2. Geld-Glaubenssätze Irgendwo tief drin glaubst du, dass es unanständig ist, viel Geld zu verdienen. Oder dass Geld verdienen Ausbeutung bedeutet. Oder dass du hart leiden musst, um Erfolg zu verdienen. 3. Angst vor Ablehnung Jede Absage trifft dich persönlich. Du gehst nicht aktiv auf potenzielle Kunden zu, weil du ein „Nein" fürchtest. 4. Unsichtbarkeit als Schutzstrategie Du arbeitest lieber im Verborgenen, weil Sichtbarkeit sich gefährlich anfühlt. Was, wenn du kritisiert wirst? 5. Überzeugung, dass es „nie genug" Kunden gibt Du lebst im Mangel-Mindset – und das überträgt sich auf deine gesamte Energie und

This show has been flagged as Clean by the host. 01 Introduction This is a follow up to my 4 part series on simple podcasting. In this episode I will discuss a number of experiments with audio filtering. These experiments were inspired by comments by listeners and by other discussions about audio on HPR. I am not an audio expert, so I am doing this partly in order to learn something, but mainly in order to have a bit of fun. I hope that you find this entertaining as well. In a comment on the first episode a listener mentioned something called Solocast and said that the method bore a resemblance to the method that I was using. Here is his comment -------------------- 02 Comment #3 posted on 2026-04-03 07:49:58 by Reto It reminds me about Solocast Hi Whiskeyjack, I really liked your podcast and the topic. I cannot remember about your last, but the sound quality of this one was good on my mobile speakers :) The concept reminded me about the program from Norrist (another host on HPR), while similar does it have some differences HPR 3496 https://hackerpublicradio.org/eps.php?id=3496 As I am not on the future feed, I look forward to your next episode. Cheers, Reto -------------------- 03 End of comment. I did not recall having heard the episode on Solocast, but this sounded very interesting. Solocast was in HPR episode 3496 and was released by norrist on the 27th of December 2021. I listened to that episode and does indeed use use the same basic concept of recording short segments of audio and combining them later instead of creating one big recording and editing it with an audio editor. 04 The main difference is that the work flow that I described involves a lot of manual steps, while Solocast is a short Python program that automates the entire process of presenting your script, recording the segments, combining the segments, and filtering and normalizing the result. I won't try to describe Solocast in detail, instead I would recommend just listening to HPR episode 3496 to get norrist's explanation directly. -------------------- 05 While I wanted to make sure that I credited norrist with having come up with this concept four years before I did, this won't be the focus of this episode. Instead I will talk about audio filtering and various experiments that I ran on several different methods. 06 While looking at the source code for Solocast I noticed that it used a filtering method that resembled one used by Jivetalk, a podcast production program that caught the attention of one of the HPR community news presenters. This method involves taking a sample of quiet audio where there is no speaking taking place, and then using this as input to a noise reduction filter which is applied to the voice recording. The filter subtracts the quiet sample from the voice audio, which should theoretically remove the ambient noise. 07 I decided to apply this method to a number of different audio test recordings which were recorded under different circumstances using different hardware. In this way I could see if the method worked equally well under all circumstances or if there were some sorts of noise which it was suited to and some sorts that were not. 08 While I was at it, I also picked several other filter methods to see how they worked as well. Potentially, some methods may be better under some conditions while other methods were better suited to others. -------------------- 09 I won't present all of my experiments, as that would be a bit dull to listen to. Instead I will describe each method and then present audio samples which illustrate my conclusions. There are two pieces of audio software involved, both of which were also used in my series on simple podcasting. 10 The first is Sox, spelled s o x , and which is short for Sound Exchange. Sox is a command line program for audio manipulation. Sox is Free Software, released under the GPLv2 or later. The other is FFMPEG, which is also a command line program. FFMPEG is also Free Software, released under the LGPL V 2.1 or later, and GPL v 2 or later. Sox actually uses FFMPEG for certain operations. -------------------- 11 Audio Hardware For recording hardware I used the following. 12 Maxwell Headset The first is a cheap Maxwell headset that has an electrical noise problem. Unfortunately I don't have a model number for this headset. I described this hardware, the noise problems that I had with it, and how I created filters to deal with the noise in my series on simple podcasting. Briefly though, this is a headset that has a build in microphone on a boom which allows the microphone to be positioned close to the mouth. It connects with a USB cable. 13 Borne Earpiece and In-line Microphone This is a set of earplugs that go in your ears and connected by wires and a very small microphone built into a small bulge in the cable. It connects using a 3.5mm jack. The model number seems to be BUD250-BL. 14 XTrike Headset This is a gaming headset similar to the Maxwell headset described above. The model number is GH-510 It uses a USB connection. 15 Yanmai Condenser Microphone This is a microphone that comes with a small tripod stand. The model number is SF-910 It uses a 3.5mm audio jack. -------------------- 16 This is not a review of the hardware. Rather, I was trying to create audio problems so that I could test ways to fix them. Therefore, do not take the above list as a recommendation of what to buy. However, you can see that I am not using any expensive audio hardware. If you want to make an HPR podcast, you do not need professional level hardware. -------------------- 17 Audio Samples The audio samples are as follows 18 Quiet This was recorded in a quiet environment at my desk. This is my normal podcasting environment and represents optimal conditions. The main reason for this method is to see how the various filter methods perform when dealing with the electrical noise from the Maxwell headset. 19 Small fan This is a small USB powered table fan approximately 10 cm in diameter. It was located roughly 40 cm or less to the left of the microphone, although this varies depending on the microphone. 20 Traffic This was along a busy street with traffic noise in the background. -------------------- 21 Filter Methods Sox noisered Filter with Audio Profile This method uses the Sox noisered filter. Here is a brief quote from the Sox documentation on this filter. Quote Reduce noise in the audio signal by profiling and filtering. This effect is moderately effective at removing consistent background noise such as hiss or hum. To use it, first run SoX with the noiseprof effect on a section of audio that ideally would contain silence but in fact contains noise - such sections are typically found at the beginning or the end of a recording. End of quote For these tests I recorded a separate noise profile to go with each test. -------------------- 22 Basic Manual Filter This is a basic high and low pass filter pair based on the work I had done in my previous series on simple podcasting. However, based on the tests that I have done for this episode, I decided to get a bit more aggressive in terms of filtering. I use a high pass filter of 120 Hz, and low pass filter of 8 kHz. The each filter is then applied twice to increase its effect. I also added band reject filters to deal specifically with 50 and 60 Hz line noise. -------------------- 23 Complex Manual Filter This uses the manually constructed filter described in my series on simple podcasting. This uses the basic manual filter plus a series of custom bandreject filters to fix specific noise problems with the Maxwell headset. -------------------- 24 FFMPEG afftdn Filter The documentation describes this as "Denoise audio samples with FFT." -------------------- 25 FFMPEG arnndn Filter The documentation describes this as "Reduce noise from speech using Recurrent Neural Networks." -------------------- 26 FFMPEG agate Filter I will pronounce this as "agate" for convenience. The documentation describes this as "A gate is mainly used to reduce lower parts of a signal. This kind of signal processing reduces disturbing noise between useful signals." -------------------- 27 Method The experimental method used was to take each noise sample and apply the different filter methods to it. Where there are parameters which can be adjusted, a script was used to generate a series of different sample files with different parameter values. Not all possible parameters were experimented with, as the goal is to see which method produces what sorts of results under different circumstances, not to get the best possible result for the samples that I happen to have. The method in each case was as follows 28 Step 1 Convert the audio file to FLAC if it is not already in that format. 29 Step 2 Apply a basic high and low pass filter described previously to each sample. The reason for this basic filtering is that it eliminates at least some undesired noise in a fairly fool proof manner, leaving less for the more advanced filter to deal with. This should allow for a better test of the filter under realistic conditions. 30 Step 3 Apply the noise reduction filter being tested. 31 Step 4 Normalize the filtered sample to 17 LUFS according to the EBU R128 standard. The EBU standard is described in my series on simple podcasting. Normalizing adjusts the audio signal to a desired loudness level. This allows for more more consistent sound levels and allows us to hear the results under realistic conditions. I normalize the audio individually for each sample as different recording hardware requires different amounts of loudness adjustment. This is different from the typical podcast process where normalizing takes place as the very last step in the process, but it was necessary in this case. 32 Step 5 Concatenate selected sample audio files to one another to allow for better review and comparing. -------------------- 33 Results The results are grouped according to the type of noise which is being mitigated. This allows for easier comparison of the effectiveness of each technique under different circumstances. I have only picked a few examples of interest out of the numerous experiments that I conducted. -------------------- 34 Quiet Recording Environment with Maxwell Headset This compares how well the various filtering methods work on the noise induced by the electronics in the Maxwell headset. This electronic noise consisted of a noise spike every 1 kHz. This should be representative of electronic noise caused by problems in recording hardware. 35 Manual Filter The manual filter applied a narrow band reject filter every 1 kHz from 1 kHz to 12 kHz. This completely removed the otherwise audible whine caused by the noise. 36 FFMPEG afftdn This method allows for setting a noise floor and then specifying how much the noise floor should be reduced by. The method is very sensitive to getting the noise floor correct for that recording. Set the floor too low and nothing happens. Set it too high, and some distortion results. However it seemed to be moderately effective, but it would seem to require checking it and possibly adjusting it each time it is used. 37 FFMPEG agate This method allows setting a noise floor and then suppressing all sound which falls below that level. This method is very sensitive to getting the noise floor correct for that recording. If set too low (or quiet), it is ineffective. If set too high (or loud), it distorts words which come after a pause, which would typically be between sentences. 38 When set correctly, it completely removes noise in the silences between sentences. However, the noise is still audible during speech. This is because the noise in this case is a higher frequency than normal speech, and so stands out more. It may not be a significant problem for noise which is closer to the main vocal frequency band. Overall, this method is not suitable for this particular problem. 39 FFMPEG arnndn This method used the standard model. A variety of different noise reduction models are available. I only tested it with one, std.rnnn It does not seem to introduce much distortion in the voice signal even with a high amount of mix parameter. 40 However, it is only slightly effective at removing the whine from the signal, even with a high amount of mix parameter. Overall, this method does not appear to be useful for this sort of noise problem. 41 Sox noisered Filter This was effective in removing noise between words, but noise can be heard while words are being spoken. It was better than agate however. 42 Overall Conclusion for the Maxwell Headset Noise When dealing with narrow noise bands that occur at known frequencies, the manual filter is leagues ahead of any of the other tested alternatives. 43 Sample Audio Here is a sample audio recording showing the best overall results The sample is repeated, first with only basic low and high pass filtering, and then with the manually constructed filtering. In the first sample you should hear a high pitched background whine. In the second sample, the high pitched whine is completely removed. 44 (Audio sample inserted here.) -------------------- 45 Traffic Noise This was recorded using the Borne in-line microphone connected to a mobile phone while walking along beside a busy street. This was in dry cool spring weather, and the road was paved with asphalt. This should be reasonably representative of podcasting while walking outdoors in a noisy environment. 46 Basic Manual Filter This used the basic manual filter with high and low pass filters. This did nothing very useful in this case as the signal was already filtered within those limits by the recording hardware anyway. The low sample rate of 8 kHz in the phone limited the upper frequency to 4 kHz. Recall that the sample rate has to be twice the highest frequency that you want to detect. Overall, this is not suitable for this sort of problem. 47 FFMPEG afftdn With a high noise floor, background noise is reduced, but not eliminated. There was not much distortion in the voice. This is only slightly useful for this sort of problem. 48 FFMPEG agate With a high threshhold, background noise is reduced, but not eliminated. There was some distortion in the voice. The background noise could also be heard when speaking, but because the frequency of the background signal was similar to the louder voice signal, it was not as noticeable as it would have been if the two were very different. This is moderately useful for this sort of problem. It may be more useful in situations where the background noise was not quite as loud. 49 FFMPEG arnndn With high amounts of noise reduction, much of the background noise is suppressed, but there is not a lot of distortion in the voice. The background traffic noise is still present, but is significantly less. This offers only a moderate improvement. 50 Sox noisered Filter With small amounts of noise reduction voice is clear but traffic noise is present as a very significant continuous warbling sound in the background. This is no improvement on the original and in fact could be seen as making it worse. With moderate amounts of noise reduction, traffic noise is mostly gone, but there are still various squeaks present. Voice is noticeably distorted. With large amounts of noise reduction, traffic noise is gone but voice is highly distorted. This is moderately useful for this sort of problem, but requires careful adjustment. 51 FFMPEG arnndn Followed by FFMPEG agate This combined two different filters. First, it used arnndn to suppress the background noise to a lower level without much voice distortion. Then it applied the agate filter to suppress the noise levels between words still further. This used the same amount of mix and threshold as was found to be most effective when each of these filters was used on its own. The background noise is almost completely gone while distortion of the voice signal is low. 52 Overall Conclusion for Traffic Noise The arnndn combined with agate filters was the most successful at suppressing background noise while limiting the amount of voice signal distortion. 53 Sample Audio Here is an audio sample for what I felt to be the best overall results, the arnndn filter combined with the agate filter. First is the original audio with basic filtering. This is followed with the same audio after being passed through the arnndn and agate filters. 54 (Insert arnndn plus agate audio sample here) 55 Another Sample Here is a second audio sample showing the Sox noisered profile based filter. I have included this to show how a profile based filter can make things worse if you are not careful how you use it. This repeats the test audio 4 times. The first is with basic filtering only. The second uses low amounts of noise reduction. The third uses moderate amounts of noise reduction. The fourth uses high amounts of noise reduction. 56 (Insert noisered audio sample here) -------------------- 57 Small Fan Noise with Yanmai Microphone This was recorded using the Yanmai condenser microphone. A small fan was set up behind and to the left of the microphone. This is intended to represent situations where someone may have a fan or air conditioner running in the background due to hot weather, or has a loud computer fan. 58 A condenser microphone was used for this test as they are more prone to picking up unwanted noise. However, for practical recording purposes, this sort of microphone is unsuitable for this type of environment. 59 Basic Manual Filter This used the basic manual filter with high and low pass filters. This did nothing useful as the fan noise was in the same frequency range as the voice signal. This may be of more help in cases where the noise is below the 120 Hz cut off used in the low pass filter. 60 FFMPEG afftdn With high amounts of noise reduction, much of the background noise is suppressed, but there is some distortion in the voice. The background fan noise is still present, but is significantly less. Overall this is moderately effective. 61 FFMPEG agate This was effective in removing noise between words, but noise can be heard while words are being spoken. However, this was a small voice sample and it is possible that more problems could occur. With less fan noise than was in this sample this technique may work much better. 62 FFMPEG arnndn With high amounts of noise reduction, much of the background noise is suppressed, but there is not a lot of distortion in the voice. The background fan noise is still present, but is significantly less. Overall this was fairly effective. 63 Sox noisered Filter With small amounts of noise reduction voice is clear but fan noise is present as a slight warbling sound in the background. With moderate amounts of noise reduction, fan noise is gone, but voice is somewhat distorted. With large amounts of noise reduction, fan noise is gone but voice is very distorted. 64 In general this method is fairly successful at dealing with this sort of problem. However, there is a trade off between background noise and voice quality. Getting that trade off correct takes experiment and judgment for each specific situation. 65 FFMPEG arnndn Followed by FFMPEG agate This combined two different filters. First, it used arnndn to suppress the background noise to a lower level without much voice distortion. Then it applied the agate filter to suppress the noise levels between words still further. This got rid of virtually all of the background noise between words. If you listen carefully however, there is a slight buzzing sound in the voice signal. 66 Overall Conclusion for Fan Noise with Yanmai Microphone. Of the methods tested, the arnndn followed by agate filter seemed to offer the most improvement for the least effort and least voice distortion. The arnndn filter on its own seemed the next most preferable to me despite leaving some fan noise in the background. 67 Audio Sample Here is an audio sample for what I felt to be the best overall results, the arnndn filter combined with the agate filter. First is the original audio with basic filtering. This is followed with the same audio after being passed through the arnndn and agate filters. 68 (Insert audio sample here) -------------------- 69 Small Fan Noise Recorded with Headset The following is an observation rather than a filtering technique. When a recording was made using the Maxwell headset and listened to on the headset later or with speakers, the fan was virtually inaudible. When the same recording was listened to with the XTrike headset, it was barely audible with careful listening and only identifiable as a fan because I knew it was there. 70 In situations where there is ambient noise, the best noise reduction technique is probably to move the microphone as close to your mouth as possible, although not directly in front of it, and reduce the gain if there is a gain adjustment in the microphone. This will work far better than trying to remove the noise later. If you are recording an HPR episode at a desk, then an inexpensive headset with boom mike may do the job just fine with minimal effort and expense. -------------------- 71 Conclusions I have tested three noise scenarios - Electronic noise in the audio hardware at specific frequencies. Recording outdoors with an inline microphone in a noisy traffic environment. A noisy fan creating background noise in an office. My conclusions on these are as follows. 72 Electronic Noise in the Audio Hardware at Specific Frequencies If you can use Audacity or some other means to find the frequencies which are causing the noise, the best solution, assuming you don't just replace the hardware, is to manually construct filters to remove those specific frequencies. This is the safest solution in terms of only doing what you tell it to and not producing unexpected surprises some time down the road when something changed in the environment. 73 If you are looking for a fairly automatic filtering method, the Sox noisered profile based filter seems to work fairly well. There is an equivalent filter in ffmpeg, but I did not include that in my experiments as it is harder to use in a script because it does not use a separate noise profile file. 74 Recording Outdoors with an Inline Microphone in a Noisy Traffic Environment. In this situation, the FFMPEG arnndn combined with agate filters seem to be the most successful. The Sox noisered filter may work, but at the cost of more distortion in the voice than is seen in the other methods. 75 An inherent problem with any profile based noise reduction method is that if the background noise is not constant, which it seldom is in that sort of environment, the profile may not represent the background noise which is present later on in the recording. This risks adding more distortion in the voice as the profile and later environments diverge. 76 However, for this application a different microphone that provided a better recording would appear to be advisable. A solution which brought the microphone much closer to the mouth and so resulted in a better ratio of voice signal compared to background noise would appear to be necessary, after which the question of what sort of noise reduction to use would need to be re-evaluated. 77 A Noisy Fan Creating Background Noise in an Office. The Sox noisered filter and the FFMPEG arnndn, afftdn, and agate methods all work to some degree. However, they all need correct selection of parameters to achieve the proper results. When I compared all four methods side by side, I found the arnndn combined with the agate filter to be preferable in terms of the trade off between background noise reduction and distortion of the voice signal. The arnndn filter on its own seemed the next most preferable to me despite leaving some fan noise in the background. 78 However, that is a subjective judgment of a specific noise sample when recorded using a specific microphone. Keep in mind though that many listeners will not be listening in an idea environment. They may be doing things where background noise is present rather than in a very quiet room and so may find a small amount of background noise in the recording to be less of a problem than distortion in the voice signal which may make some words harder to understand. 79 When I conducted the same experiment recorded with the XTrike headset I found that arnndn seemed to offer no noticeable improvement. This may be because the amount of audible fan noise was far less with the XTrike headset to begin with. In other words, there is no single best solution here, and you may have to be prepared to try different options to see which one works in your situation. The important thing is to avoid making things worse by applying filtering that is not appropriate for that situation. The best method may be to use a recording method that doesn't pick up the fan noise to begin with. This can include just using a gaming headset with boom mic. 80 I have one final observation on this point regarding headsets. The Maxwell headset has a foam cover over the microphone while the XTrike headset does not. There was some slight audible wind buffeting noise picked up by the XTrike headset that was not observed with the Maxwell. This seemed to cause particular problems with the Sox noisered profile based filter, as this noise was irregular and after filtering would show up as a warbling sound. If you use a headset and plan to use it in conjunction with a fan, it may be advisable to apply some sort of wind cover over it. 81 Combining Complex Filters In several cases I found that combining several complex filters offered better results than using any single one on its own. The basic strategy though is to first use a method which is good at reducing undesirable noise without introducing excessive voice distortion. Then apply a different filter which is good at reducing small levels of background noise to an even lower level while affecting the voice signal as little as possible. This uses the relative strengths of different filter types to compensate for the weaknesses of the other. 82 Different combinations of filters were most effective for different types of problems. I did not try all possible combinations however. Perhaps a further exploration of this would be worth doing in a later podcast. -------------------- 83 Case Study - Noise in Another HPR Episode Audio In the comments to my second episode on Simple Podcasting (which is HPR4618) where I discussed basic filtering, a couple of listeners brought up an interesting point. Antoine mentioned "declicking" in a post. -------------------- Vance replied 84 Antoine, thanks for mentioning the click removal capability in Audacity! While I already knew about its noise removal filter, I wasn't aware it also had click removal. It might have helped me for HPR4637, where some sort of electromagnetic signal was picked up by my microphone/recorder, a Zoom H2 (the tapping sound was *not* present in the room where I recorded). While click removal does seem to distort speech when applied to it (though to my ears, it doesn't sound as weird as when noise removal is done with speech), I could have applied the filter only to the pauses, where the "tapping" is most noticeable. I will consider doing this in the event that I'm not able to eliminate the source of interference in the future, which would be the best way to go. -------------------- 85 End of quote. I found this interesting as it sounded like another audio problem that could be experimented with. I found a sample of the episode which had the clicks and cut a copy of that segment out to experiment with. These sounds are a series of clicks, or "ticks" would be another way to describe them, in the quiet part of the audio between sentences or phrases. 86 Next I used Audacity to study the sound spectrum. I found a massive 60 Hz noise spike. However, my speakers won't reproduce sound that low, and filtering this out didn't reduce the clicks. The clicks turned out to be bursts of noise across the 100 to 800 Hz band, which is right where the main vocal band also is. This makes it difficult to filter based on frequency. The most promising approach would seem to be to filter based on sound level. 87 I tried all of the individual audio filter techniques mentioned in the other experiments above. None produced satisfactory results except for agate, which makes quiet audio quieter. This completely suppressed the clicks. However, when applied to the entire episode it also distorted the start of a few sentences which began with single short syllables. 88 The agate filter has a number of parameters which could be adjusted to try to deal with these cases, although I did not spend the time to do so. Another solution to this distortion problem is to simply not apply the filter to those parts of the audio which are affected. If you record the audio as a series of small individual files, it would be easy enough to filter before concatenating the files together while skipping those files which contain audio which is not suited to this method. Here are the results of the experiments. 89 FFMPEG afftdn This reduces the size of of the ticks, but they are still present. However, they may be reduced to a level which is considered acceptable. 90 FFMPEG agate This was very effective in removing ticks with the right parameters. However, it can introduce some voice distortion in the form of cutting out the start of a few sentences which began with single short syllables. This can be corrected with a very short "attack" parameter to turn off the filter when it detects sound above a set threshhold. 91 FFMPEG arnndn This was relatively ineffective. 92 Sox noisered This was effective in removing the sounds between phrases. However, it introduces some distortion in the voice signal. 93 I also tried combining filters. FFMPEG afftdn Followed by agate This combined two different filters. First, it used afftdn to suppress the background noise to a lower level without much voice distortion. Then it applied the agate filter to suppress the noise levels between words still further. This got rid of virtually all of the background noise between words. 94 Here is a short audio sample from HPR4637. First is the unfiltered audio. Second is the filtered audio using the combined afftdn plus agate filters. Since the "clicks" are very quiet, you may not hear them unless you are in quiet environment. Quite a few listeners would probably not be aware of the perceived audio problem in this episode if it had not been discussed here. None the less, it makes for an interesting experiment. Here it is: 95 (Insert sample audio here) 96 Overall Conclusion for Noise "Ticks" The afftdn combined with agate filters seemed to offer the best overall results when used with the right parameters. However, the author, Vance, speaks very clearly and evenly, and so his voice is ideally suited for use with this filter. Another author's voice may not be as suited to this filter. 97 The Sox noisered profile based filter offers various degrees of trade off between suppressing noise and distorting the voice signal. As to whether this is an acceptable trade off depends on the particular voice in question and how easily understood it is under normal circumstances with out additional distortion. The afftdn filter may be a fairly safe filter to use on its own while producing acceptable if not perfect output. -------------------- 98 Overall Conclusions I have presented only a few of the experiments that I conducted. My overall conclusion after all of this is that there is no universal audio filtering method that works best in all circumstances. There are instead a number of tools in the toolbox, and picking the right one for the job takes a bit of trial and error. 99 However, if you have a repeatable recording environment, then once you have decided what tool you need you should create a script for it so you can have a repeatable processing setup. These conclusions apply to voice podcasting. Music has a different set of criteria and techniques that work well with basic voice podcasting may produce poor results when applied to music which has a broader range of frequency and just as importantly, a broad range of loudness. 100 If you are used to using filters and effects in Audacity, many of the settings on those correspond to arguments in the command line version of ffmpeg. It is worth learning how to use ffmpeg directly to automate your recording process. 101 The experiments that I conducted were greatly assisted by writing scripts which created multiple versions of audio files with different settings, thereby allowing me to try many different alternatives relatively easily. It also allowed me to concatenate different audio samples into a single audio file and so listen to different versions in quick succession, making subjective listening judgments more reliable. 102 It is important to keep in mind in all this that I am playing with audio filtering mainly to have fun. It is not necessary to do any of this if you think your podcast episode sounds just fine without it. So, don't let any of what I have talked about in all this discourage you from simply recording a podcast and sending it in as is. I will include copies of the filters I have described here in the show notes. -------------------- 103 Related Matters Hardware Characterization Using Audio Signals I found it useful to characterize the hardware that I had in order to understand its limitations better before starting the experiments. This involved playing a signal out through a set of speakers and then recording it through a microphone. 104 I used two types of signal for this. One is type of signal is known as a "chirp" signal. This is a sine wave that steadily increases in frequency as it sweeps across the audio spectrum. The standard audio range is 20 Hz to 20 kHz, but for my purposes I limited the upper frequency to 15 kHz to save time as anything beyond that is not very useful for voice podcasts. 105 By recording the chirp signal with a microphone and analyzing it with a Fourier transform, I could quickly see what each device was capable of. See my previous series on simple podcasting for an explanation of what a Fourier transform is and what software to use to see the results of it. Here is a chirp signal. 106 (Insert Audio Sample Here) 107 In addition to a chirp signal, I also used a series of simple tones of specific frequencies. By using these tones of known frequency I could gain an understanding of the limitations of my speakers and headphones, and just as importantly, my own ears. By understanding these limitations I was able to narrow the range of frequencies that I need to deal with quite considerably and set the high and low pass filters accordingly. These tones are a series of flac files generated with ffmpeg. 108 Here is a a sample audio tone at a 2 kHz frequency. 109 (Insert Audio Sample Here) 110 Copies of the script to create the chirp signal and the tones are in the show notes. -------------------- 111 A "Not a Review" of some of the Hardware that I Used I said that I would not do a review of the hardware that I used. However, some of it deserves mention for either how good or bad it was. I will record each section using the hardware being described. 112 Maxwell Headset This is my original recording hardware. This is a headset with boom mic and USB connection. There is no model number on it, so I don't know the model. This probably cost somewhere between 10 and 25 dollars. The earpieces sit on the ears and do not fully enclose them. This makes it light weight and comfortable to wear for extended periods of time. It has a problem however with electronic noise consisting of a noise spike every 1 kHz. I was able to fix this with a series of filters using FFMPEG. Fixing this problem is what got me started in understanding audio. I will probably continue to use this headset to make podcasts. 113 XTrike Headset, Model GH-510 This is also a headset with boom mic and USB connection. I purchased this headset for the purposes of experimentation for this podcast episode. It cost $12.88. I found it to be surprisingly good for the price. It has fully enclosed ear pieces however, which may make it uncomfortable to wear in hot weather. I may try doing some of my future podcasting using this headset. 114 Borne Earpiece and In-line Microphone This is a set of earplugs that go in your ears and connected by wires and a very small microphone built into a small bulge in the cable. It connects using a 3.5mm jack. The model number seems to be BUD250-BL. It cost approximately $3.00. I bought several sets of these and use them for listening to podcasts from an MP3 player. The ear pieces are pretty good for listening with. The microphone works reasonably well when used in a quiet location. It is less good when in a noisy environment. It is very important however to secure the microphone to your lapel or other location reasonably near your mouth and to point the microphone (that is the small hole) outwards and not simply let it dangle freely. If you let it just hang, you will get poor quality and inconsistent audio. 115 Yanmai Condenser Microphone, Model SF-910 I purchased this microphone for the purposes of experimentation for this podcast episode. It cost $3.88. As it is a condenser microphone, it is prone to picking up background noise more and as such is probably not a good choice for podcasting by single person sitting at a desk. However, it is none the less a surprisingly good microphone for surprisingly little money. 116 iCan USB Microphone, Model M-306 I purchased this microphone for the purposes of experimentation for this podcast episode. This has a USB connection. This was also relatively inexpensive at $7.99, or roughly twice the price of the Yanmai microphone. Unlike the Yanmai however, it is absolutely wretched. There was such a high degree of distortion when recording through it that I found I could not use it in the fan experiments which I had bought it for. I ended up buying the Yanmai microphone for that instead. -------------------- 117 Easy Effects Software The techniques described so far all involve recording audio files and then processing them later to produce the desired result. This is probably the simplest and most straightforward way of doing things if you are making a typical podcast. However, there may be instances where you want to apply filtering or other effects on the "live" signal immediately and not after the fact. 118 There is audio software which can hook into your computer's audio system and do this with a live signal. For Linux, there is a package called "Easy Effects". This is Free Software and comes under a GPL V3 or later license. I installed it from the Debian repository under Ubuntu 24.04. 119 You can create various filters and even chain them together to combine them. I played with it a bit but do not know enough about it to discuss it seriously at this time. However, I thought it would be worth mentioning for the sake of those who may wish to try it out themselves. -------------------- 120 Episode Conclusion After having had some fun with audio and listening to other HPR members talk about audio, I thought I would have some more fun by playing with noise reduction filters. I have no intention of becoming an audio professional, but by doing some experiments I learned a few things and had some fun doing it. I hope that the rest of you found this interest as well. I will see you all again later in another episode of Hacker Public Radio. -------------------- Scripts Basic Filter This shows basic high and low pass filters ( 120 Hz and 8 kHz respectively) and band reject filters for 50 and 60 Hz. # The high and low pass filters. hlpfil="highpass=f=120, highpass=f=120, lowpass=f=8000, lowpass=f=8000" # Band reject filters filter for 60Hz and another for 50Hz. linefil="bandreject=f=60:width_type=h:w=20, bandreject=f=50:width_type=h:w=20" # Filter using ffmpeg. ffmpeg -i inputfile.flac -af "$hlpfil, $linefil" outputname.flac # ====================================================================== afftdn Filter # noisefloor should be between 20 and 80. noisefloor=$1 # Run the noise reduction. ffmpeg -i testrec-filtered.flac -af "afftdn=nr=10:nf=-""$noisefloor" tmptestrec.flac # ====================================================================== agate Filter # threshold shoud be between 10 and 80. threshold=$1 # Run the noise reduction. ffmpeg -i testrec-filtered.flac -af "agate=threshold=-"$threshold"dB:range=-60dB" tmptestrec.flac # ====================================================================== arnndn Filter # mix should be between 0 and 1. mix=$1 # Run the noise reduction. ffmpeg -i testrec-filtered.flac -af 'arnndn=model=std.rnnn:mix='"$mix" tmptestrec.flac # ====================================================================== sox noisered Filter # Generate the noise profile from a sample of background noise. sox silencefiltered.flac -n noiseprof noise.prof # nramount shoudl be between 0 and 1 sox testrec-filtered.flac noiseout-testrec.flac noisered noise.prof "$nramount" # ====================================================================== Manual Filter for Maxwell Headset Noise # Create a series of band reject filters, from 1 kHz to 11 kHz. ftemplate="bandreject=f=%s000:width_type=h:w=100" kilospikefil=$( seq 1 11 | xargs printf "$ftemplate," ) # Using ffmpeg ffmpeg -i testrec-filtered.flac -af "$kilospikefil" tmptestrec.flac # ====================================================================== Create a "chirp" signal # Start frequency. f0=20 # End frequency. f1=15000 # Duration of signal. duration=10 ffmpeg -f lavfi -i "aevalsrc=sin(2 * PI * (0.5 * ($f1 - $f0)/$duration * t^2 + ($f0 * t))):s=44100:d=$duration" -c:a flac -af "aformat=sample_fmts=s16" chirp.flac # ====================================================================== Generate Audio Tones toneout () { printf -v freqval "%05d" $1 ffmpeg -f lavfi -i "sine=frequency=$freqval:duration=3" tmptone.flac # Normalize ffmpeg -i tmptone.flac -af loudnorm=I=-17:TP=-2.0:LRA=4.0 -ar 44.1k -sample_fmt s16 tone$freqval.flac rm tmptone.flac } # List of frequencies in hertz. freqlist="50 60 100 120 130 140 150 160 170 200 500 1000 2000 3000 4000 5000 6000 7000 8000 9000" for freq in $( echo $freqlist ); do toneout $freq done # ====================================================================== Provide feedback on this episode.

No two adoption journeys look the same — and that's exactly what makes this conversation so powerful.In this special panel episode, Rebecca sits down with three adoptive parents whose paths to parenthood couldn't be more different: Lisa, a single mom by choice; Kirk, an adoptee turned adoptive father raising a son with his husband; and Jennifer, who navigated infertility, open adoption, and the unexpected twists that ultimately led her to her daughter.Together, they share the moments that challenged them, surprised them, and ultimately shaped the families they have today. From navigating fertility struggles and years of waiting to sitting beside birth mothers in hospital rooms and welcoming children through adoption, this conversation is filled with the kind of honest insight only lived experience can provide.Whether you're just beginning your adoption journey or are already parenting through adoption, this episode offers reassurance, perspective, and a reminder that there is no one right way to build a family.In this episode, we talk about:• The moment each family knew adoption was the right path for them• The assumptions they had about adoption that turned out to be completely wrong• How open adoption looked different than they expected• The reality of fall-throughs, waiting, and navigating uncertainty• What it was like meeting birth parents and being in the hospital for placement• How their unique family structures shaped their adoption experiences• Raising children through adoption while honoring identity, culture, and belonging• The lessons they've learned that they wish every hopeful adoptive parent knew• Why so many of them nearly gave up — and why they're grateful they didn'tAbout Our Guests:Lisa is a single mom by choice who built her family through adoption after navigating both fertility treatments and foster care. Her journey offers a unique perspective on perseverance, parenting, and embracing the unexpected path to motherhood.Kirk is an adoptee and adoptive father who, alongside his husband, welcomed their son through adoption after experiencing multiple fall-throughs and a NICU placement. His perspective bridges both sides of the adoption experience as both a child and parent touched by adoption.Jennifer is an adoptive mother, licensed clinical social worker, and advocate for open adoption. Alongside her husband, she welcomed her daughter through adoption and shares openly about building relationships with birth parents, navigating uncertainty, and parenting with empathy and connection.Together, their stories highlight the many different ways families are built through adoption — and the common threads of resilience, hope, and love that connect them all.RG Adoption ConsultingWebsite → ⁠https://rgadoptionconsulting.com⁠ Book a Complimentary Adoption Strategy Session → ⁠https://rgadoptionconsulting.com/contactAre You Ready to Adopt?

Wie verändert KI die Art, wie wir künftig einkaufen? Und welche Rolle spielen dabei Live-Shopping, Re-Commerce und Agentic Commerce? Darüber spricht Verena Gründel mit Saskia Meier-Andrae, Vice President and General Manager, eBay Germany & Central Europe. Die Art, wie Menschen Produkte suchen und entdecken, steht vor einem grundlegenden Wandel. Für Saskia Meier-Andrae ist klar: Die klassischen Filter auf Websites könnten schon bald Geschichte sein. Statt mühsam Kategorien, Größen und Preise auszuwählen, werden Nutzer künftig in natürlicher Sprache mit intelligenten Systemen interagieren. Die KI kennt Vorlieben, Größen, frühere Käufe und sogar den Inhalt des Kleiderschranks. Produktsuche wird dadurch persönlicher, intuitiver und deutlich komfortabler. Gleichzeitig entstehen neue Herausforderungen für Händler und Plattformen. Denn wenn KI-Agenten den Einkauf übernehmen, stellt sich eine zentrale Frage: Wer besitzt künftig die Kundenbeziehung? Besonders spannend ist Saskias Blick auf Live-Commerce. Während viele Menschen dabei sofort an Teleshopping denken, sieht sie darin vielmehr eine Mischung aus Community, Entertainment und Commerce. Bei eBay stehen nicht austauschbare Massenprodukte im Mittelpunkt, sondern häufig einzigartige Artikel: Luxusuhren, Vintage-Handtaschen, Sammelkarten oder Refurbished-Produkte. Händler präsentieren ihre Ware live, beantworten Fragen der Community und schaffen Vertrauen durch direkte Interaktion. Ein entscheidender Unterschied zu vielen KI-getriebenen Entwicklungen: Live-Commerce lebt von Menschen. Spannende Zahlen aus dieser Episode: Rund 40 Prozent des eBay-Umsatzes stammen bereits aus nicht neuer Ware. In Asien werden bereits etwa 35 Prozent des E-Commerce-Umsatzes über Live-Commerce generiert. Der globale Live-Commerce-Markt soll laut Prognosen von 25,6 Milliarden auf 74,5 Milliarden US-Dollar bis 2030 wachsen. eBay Live ist mittlerweile in sieben Ländern verfügbar. Der weltweite Außenumsatz von eBay Live hat sich gegenüber dem Vorjahr verachtfacht. Einzelne Luxusuhren-Verkäufe erzielen in Livestreams Preise von über 90.000 Euro. Hör jetzt in die Folge rein und entdecke, wie sich das Einkaufen der Zukunft entwickelt.

In Matthew 6:19-24, He reveals how our priorities shape our hearts and how distorted perspectives can keep us chasing things that never satisfy.This message explores the hidden filters that influence our financial decisions and how following Jesus brings clarity, freedom, and a healthier relationship with money

Microplastics and Stroke Risk: What a Landmark 2024 Study Found Inside Human Arteries In 2024, a team of Italian researchers published a study in the New England Journal of Medicine that stopped the cardiovascular science community in its tracks. They found microplastics, tiny synthetic fragments embedded inside the carotid artery plaque of more than half the patients they examined. And the patients who had them faced more than four and a half times the risk of a serious cardiovascular event compared to those who didn’t. This isn’t a distant, theoretical risk. These are living people who had already been identified as having carotid artery disease, and plastics were found inside their arterial walls. For stroke survivors and those at elevated risk of stroke, this study raises important questions that the medical system has not yet caught up with. What the Research Found The study by Marfella et al., published in the New England Journal of Medicine (2024), enrolled 304 patients who were undergoing carotid endarterectomy, a surgical procedure to remove plaque from the carotid arteries. Researchers analysed the excised plaque for the presence of microplastics and nanoplastics. Their findings: 58% of patients had detectable levels of polyethylene, polyvinyl chloride (PVC), or polystyrene in their arterial plaque. This was not contamination from the surgical procedure; it was already there. Over a 34-month follow-up period, patients with microplastics in their plaque had a 4.53 times higher risk of a combined endpoint: non-fatal myocardial infarction, non-fatal stroke, or death from any cause. Inflammatory markers were significantly elevated in the microplastics-positive group. IL-18 and TNF-alpha proteins associated with systemic vascular inflammation were markedly higher in plaque samples that contained plastics. This suggests the mechanism is not simply physical obstruction, but an inflammatory cascade triggered by the presence of synthetic material in arterial tissue. What This Means for Stroke Survivors The carotid arteries are the primary conduits supplying oxygenated blood to the brain. Plaque accumulation in these vessels is one of the leading causes of ischaemic stroke, and carotid artery disease is a condition many stroke survivors are already living with. “The patients with microplastics in their plaque had a 4.53 times higher risk of stroke, heart attack, or death over the 34-month follow-up. That’s not a marginal finding. That’s a signal the research community needed to take seriously.” The NEJM study doesn’t yet tell us whether removing microplastic exposure after the fact reduces risk. It doesn’t confirm that healthy individuals with no existing carotid disease are accumulating plastics at the same rate. And it cannot tell us which plastic sources are most responsible because we’re exposed to microplastics through drinking water, food packaging, air, and a dozen other vectors simultaneously. But what it does tell us clearly and with high statistical significance is that microplastics in arterial plaque are associated with dramatically worse cardiovascular outcomes. What the Research Does Not Yet Tell Us Science at the frontier moves in one direction at a time. This study establishes association, not causation. It cannot yet answer: Whether people without existing carotid disease are accumulating microplastics at comparable rates. Whether reducing exposure actively reverses or slows plaque-associated risk. Which types of microplastics are most biologically harmful? Whether there will be a clinical screening tool for this in the near future. These are the questions the next generation of research will need to answer. In the meantime, it’s reasonable to act on what we do know. Practical Steps to Reduce Exposure No clinical screening currently exists for microplastics in arterial plaque. There is no blood test, no imaging, no biomarker that your GP can order today. What you can do is reduce your ongoing exposure, particularly through food and water contact with plastics. Evidence-informed steps worth discussing with your treating team: Use glass, stainless steel, or ceramic containers rather than plastic for food and drink storage. Avoid microwaving food in plastic containers; heat accelerates the leaching of plastic particles. Filter your drinking water; some filters (carbon block and reverse osmosis) reduce microplastic levels significantly. Reduce consumption of highly processed foods in plastic packaging.

Filter - Bad Guy Éric Serra - The Diva Dance -- Hosting provided by SoundOn

Filter cleaning is where “simple maintenance” turns into stuck lids, mangled threads, mystery leaks, and the one moment on a job that can actually hurt you. We walk through the common pool filter problems that almost never get talked about, especially on D.E. filters and quad cartridge filters with metal clamps and spring barrel nuts, and we share the exact fixes we use when a filter top refuses to seat back onto the tank.We get specific about the real culprit behind most hard-to-close lids: a worn or wrong O-ring, even when it looks perfectly fine. You'll hear why brand-specific O-rings matter, how silicone spray and Magic Lube change the game, and what to do when the clamp hardware won't thread or starts shedding metal because it's cross-threaded. We also cover tightening and verification tips, including using a multi-torque socket and a rubber mallet to eliminate slack, because a clamp with gaps is not just a leak risk, it's a safety risk.From there we shift to other route realities: single cartridge filters with overtightened plastic rings, debris-packed threads, and the fastest way to break them loose without breaking equipment. We also talk about fiberglass filter tanks that leave your arms itching for days, plus simple protection steps like long sleeves and even wrapping the lid. To round it out, we dig into drain plug headaches, leaking drain plug O-rings, and backwash valve problems, including push-pull piston valve O-rings, multi-port spider gasket symptoms, and a temporary ball valve trick that can buy you time until the proper repair.If this helps, subscribe so you don't miss the next one, share it with a tech who's fighting a filter clamp right now, and leave a review with your go-to filter cleaning tip.We share the pool filter cleaning problems that blindside even experienced techs, from lids that refuse to seal to clamps that can become a real safety hazard. We also walk through practical tool-and-process fixes you can use on route to prevent leaks, reduce damage, and avoid painful mistakes.  • brand-specific filter O-rings and why “looks fine” can still fail  • silicone spray and Magic Lube methods to help lids seat and extend O-ring life  • safer filter cleaning by removing the pump lid to prevent pressure buildup  • spring barrel nut and clamp tricks when threads will not catch  • spotting cross-threading and when replacement is the only smart move  • freeing overtightened single cartridge rings with a rubber mallet  • preventing fiberglass tank itching with sleeves or saran wrap  • drain plug wrench options, leak risks, and spare drain plug O-rings  • push-pull piston valve symptoms and O-ring replacement guidance  • multi-port spider gasket failures and a temporary ball valve workaround  Are you a pool service pro looking to take your business to the next level?

Bob Keppel was one of the King County detectives who could see the pattern forming in the spring of 1974. Same age range. Same appearance. Same young man on crutches or in a sling. The Seattle papers started using the word pattern. The Task Force opened a tip line. The phone did not stop ringing.By summer, the Ted Task Force had a composite, a first name, and a car description from witnesses at Lake Sammamish, where the man calling himself Ted had taken two women from a crowded beach in a single afternoon. The tips eventually exceeded two hundred thousand names.Three of those tips came from people who knew Ted Bundy personally. His girlfriend Elizabeth Kloepfer reportedly called. Crime writer Ann Rule, who worked a crisis line with him, reportedly called. A psychology professor reportedly called. The name Ted Bundy appeared on three separate cards inside the same file.The Task Force ran a computer cross-reference at the University of Washington. Bundy made the top hundred suspects. He was ranked down — no criminal record, good apartment, law student. The picture in every detective's head of the man doing this did not match a clean-cut campaign volunteer.The right name sat in a stack while women kept disappearing and families waited for phone calls that would not come for months. When the remains at Issaquah were found in September, the killings had already stopped — because Bundy had driven to Utah.This is the first of five conversations on Ted Bundy: History's Hidden Killers. The investigative failure that let him stay hidden for an entire year, told through the names of the women whose lives were the cost.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?

In this episode, HVAC veteran Adam Mufich of National Comfort Institute (NCI) pulls back the curtain on one of the industry's most overlooked problems: the majority of residential HVAC systems in the United States are not delivering the correct amount of airflow. Drawing on decades of hands-on experience, Adam opens up about his own journey from confident installer to humbled diagnostician, sharing the moment he started measuring his systems and realized how much he had been getting wrong. His candor and expertise make this a must-listen for any HVAC professional serious about doing better work. Adam walks listeners through a sobering picture painted by a Department of Energy study covering 44 research projects across the country. The data reveals that between 50 and 93 percent of systems tested moved less than the minimum 350 CFM per ton of capacity, and between 67 and 100 percent of systems leaked more than 100 CFM to the outside. Equipment oversizing is rampant, with some studies showing that up to 93 percent of systems exceed what Manual J calculations would call for. The ripple effects are enormous: compressor failures, blown blower motors, cracked heat exchangers, wasted energy, and homeowners who are simply not comfortable in their own homes. Adam argues that the single most powerful fix is also the most underused one — properly sizing the equipment in the first place. The bulk of the episode dives into two distinct approaches NCI teaches for addressing these problems. The first is the Air Upgrade, a targeted set of repairs focused near the equipment to reduce static pressure and increase fan airflow. This includes reworking the filter system (a commonly undersized 16x25x1 filter can triple the allowed pressure budget on its own), improving duct fittings with lower equivalent lengths, cleaning evaporator coils and blower wheels, adjusting fan speed, and sealing duct joints. The second approach is full Duct Optimization, a more comprehensive renovation that addresses the entire duct system, incorporates Manual D calculations, installs balancing dampers, improves insulation, and uses tools like flow hoods and MeasureQuick to verify that every room in the house is receiving the correct airflow and BTUs. Adam also spends time on the practical and human side of this work — how to talk to homeowners, how to prioritize what matters to them, and how to overcome the very real obstacles that keep technicians from doing thorough airflow work. He addresses everything from fear of opening walls (his solution: build relationships with drywall contractors and offer turnkey repairs) to the simple but powerful mindset shift of treating airflow as something to be measured, not felt with your hand. His closing message is clear: the tools and methods exist, the training is available, and virtually every house in the country has a problem worth solving. The only thing standing in the way is the willingness to do it right. Topics Covered The current state of the HVAC industry based on a DOE meta-analysis of 44 studies Why equipment oversizing is the number one contributor to airflow problems and how to address it How a 50 percent oversized AC system can increase energy consumption by up to 91 percent (per the ASME Journal of Sustainable Buildings) Tools for proper load calculations, including Ample Energy and Conduit apps Why most systems are not moving enough airflow and what the consequences are (heat exchanger failures, compressor failures, comfort complaints) Duct leakage to the outside and its effects on comfort, indoor air quality, and building pressurization The four pillars of NCI's approach: safe, healthy, comfortable, and efficient systems The Air Upgrade approach: targeted repairs near the equipment to reduce static pressure and increase fan airflow The Duct Optimization approach: full duct system renovation with balanced airflow to every room Static pressure profiling: taking four measurements (before/after filter and before/after coil) to pinpoint restrictions Static pressure budgets and how to use them to identify which part of a system is the biggest problem Fan Law 2 as a planning tool to predict system performance before making changes The TrueFlow Grid and its forecasting feature for planning equipment changes Filter sizing and its massive impact on total external static pressure Duct fitting equivalent lengths and how to reduce resistance near the equipment Sealing duct joints and why it adds static pressure that must be planned for The importance of rechecking and adjusting refrigerant charge after any airflow improvement Air balancing with a flow hood to verify delivered CFM at every register Measuring delivered BTUs using tools like MeasureQuick, JobLink, and NCI's ComfortMax workflow Overcoming obstacles: technician buy-in, access to ducts in walls, attic space limitations, and homeowner hesitation Building relationships with drywall contractors to offer turnkey duct repair solutions Why airflow is invisible and why measuring it is non-negotiable   To learn more about NCI and its training offerings, visit https://www.nationalcomfortinstitute.com/.
