  • 32 Bit Floating Point Explained

    I found this really good video (from Allen at Sound Speeds) explaining 32 bit floating point and now things make more sense to me.

    My clarifications and takeaways:

    • It’s the “Floating Point” in 32 bit Floating Point that makes it special, as opposed to standard 32 bit resolution which behaves the same as regular 24 bit and 16 bit, etc.
    • 32 bit Floating Point uses 2 ADC’s (analog to digital converters) — one handles regular level audio and the other handles loud audio above a certain loudness level.
    • The difference in noise floor between 24 bit and 32 bit floating point is negligible or zero.
    • For regular podcast recording, as long as nobody’s level is completely blown out and distorted, it’s not necessary to record in 32 bit floating point.

    Specifically with regard to how the Sound Devices MixPre II series achieves such high dynamic range in 32-bit float mode: The MixPre II recorders feature Sound Devices’ own patented topology of multiple analog-to-digital converters. These converters appear in the circuitry after the Kashmir microphone preamplifier stage. They enable the recording of very-low distortion, ultra-high dynamic range audio. The MixPre II’s A-to-D’s can resolve more than 142 dB of dynamic range. Together with their Kashmir microphone preamplifiers and 32-bit float files, the MixPre II captures audio that is limited only by the capabilities of the microphone.

  • Be Aware: Some Earbuds Feed Back Within Themselves

    Be Aware: Some Earbuds Feed Back Within Themselves

    Sometimes when you connect with a guest to record an episode, you will hear your voice coming back on the guests audio on a slight delay and at a relatively low volume. There can be several reasons for this, but one reason can be that the guests earbuds themselves are feeding your voice back to you.

    This is because some wired earbuds feed back within themselves. When the guest hears your voice, some of your voice bleeds into their earbuds microphone. And there’s no fix for this because it’s a hardware issue within the earbuds themselves.

    Note: The feedback will get louder the more the guest cranks up their monitor volume in the earbuds.

    Whenever this problem occurs, I ask guests to turn down their monitor volume as much as they can while still being able to hear other participants, of course. This minimizes (and usually eliminates!) the feedback on their track.

    If the feedback is too loud and ruining the audio, you can:

    • Ask the guest if they have any other headphones/earbuds they can use.
    • Use the echo-cancellation feature in platforms like Squadcast and Zencastr. This will eliminate the feedback, but then of course you’ll have to deal with the “ducking” problem — when 2 people talk at the same time, one of them will literally be muted.

    Have you ever dealt with this problem?

  • Managing the Expectations of Your Clients

    If you are producing audio for clients it’s vital that you carefully manage their expectations of you as well as your expectations of them.

    When you and a client are crystal clear on what is expected from each other in the working relationship, there will be MUCH less confusion and uncertainty because you have a definitive framework within which you both can work confidently. And moving forward there will almost never be any surprise or shock to them or you.

    Some specific areas which you will want to be clear on (among many others): Launch timing, turnaround time for producing episodes, method and timing for requesting edits, guest communications, etc.

    Have you ever had trouble managing clients?

  • The Sound in the Game “Among Us”

    The Sound in the Game “Among Us”

    Among Us is a wildly popular online game and recently I was watching a streamer play and I noticed that when the characters move on the screen they move in the stereo spectrum! For instance, when a player moves their little character to the left side of the screen, the sound of their footsteps moves to the left side of the stereo spectrum. Pretty cool.

    And probably each players stereo mix is custom-generated for them depending on who is around them on-screen and and where they are in the stereo spectrum.

    Have you noticed this too?

  • Descript’s NEW Transcription Glossary

    I always wondered whether Descript‘s transcription process would properly transcribe proper nouns like Audio-Technica or tricky words like fractalchris. Well…

    From Descript: One of our most requested features has arrived. Now you can add proper nouns — like Descript! — and other tricky words Descript has trouble with to a transcription glossary. Once you add a word to the transcription glossary, it’ll show up across all your Projects on that Drive. To access and update the transcription glossary, click the arrow next to your Project’s name. The transcription glossary doesn’t currently work with live transcription, but you can expect that functionality next year.

    I don’t use Descript, but have you tried adding any words to your transcription glossary? Does it help Descript recognize and transcribe those words?

  • Low Level Compression

    Low Level Compression

    Low Level Compression, as it’s described and used in the MV2 and MaxxVolume plugins from Waves, basically brings up the volume of quieter parts of the audio. This can be very helpful when producing podcast audio where a participant get very quiet at times, for example trailing off at the end of sentences, etc. I recently purchased those two plugins but haven’t tried them yet (!!!).

    Fabfilter calls their similar processing Upward Compression and they explain it in detail in this video.

    And of course the Vocal Rider plugin from Waves can give similar results as well.

    Some podcast episodes are unlistenable due to way too much dynamic range, and the types of plugins mentioned in this post can correct those episodes and provide a good listening experience to the listeners.

    Have you used any plugins like these?

  • Major Changes to RINGR

    Major Changes to RINGR

    I’ve used Ringr in the past and it’s a good platform for recording podcast interviews over the internet. Also check out two other posts I wrote about Ringr: Ringr for Recording Guests Online, and My Frustration with Ringr.

    They recently announced some major updates to their service:

    1. No more waiting for audio uploads. Once your call is over, it’s over. Both sides can close the app or the browser window immediately and without worry.
    2. RINGR now works on mobile browsers. While the RINGR Mobile app is still amazing, your guest can now use their phone or tablet without downloading it.
    3. Connecting is more seamless than ever. Thanks to a completely rebuilt platform, RINGR connects and syncs no matter the network, device, or operating system.

    How do you get the new RINGR? If you use RINGR on your desktop or laptop, do nothing. You’re good to go. If you use the RINGR Mobile app, make sure you’ve downloaded the latest version from the App Store or Google Play.

    Have you used Ringr? What was your experience?

  • The Audio Quality of Apple AirPods’ Microphone

    The Audio Quality of Apple AirPods’ Microphone

    I’ve engineered many podcast recording sessions where the guest used AirPods as their microphone and monitors. I’ve also done post-production on all that recorded AirPods audio. It’s my conclusion that AirPods are wonderfully handy for phone calls and listening to music, etc., but they are not that great for recording podcast audio. Their microphone just doesn’t sound that good (in terms of professional audio quality).

    I’ve had lots of trouble finding the technical specifications of the frequency response of the microphone used in various lines of AirPods. If you can find these data please share them in the comments below 😉

    As I mention in my 2019 post titled AirPods and Zencastr, like Oil and Water, I believe the sample rate of some/most/all AirPods is 16kHz which is not great, not terrible. But I’d bet that it’s the Bluetooth connectivity that severely diminishes the audio quality of AirPods.

    Have you had to produce AirPods audio? What was your experience?

    Other Notes:

    New plugins I bought after Black Friday / Cyber Monday:

    What did you learn in this episode? Let me know by commenting below.

  • My Recent Plugin Purchases (Black Friday/Holidays)

    My Recent Plugin Purchases (Black Friday/Holidays)

    Below is a list of plugins that I recently purchased on sale around Black Friday.

    Some are not often used in podcast production, but I bought them for music production. (Decapitator, Melodyne 5, Quadravox)

    The 3 that I absolutely LOVE are the first 3 listed.

    Trackspacer acts like an intelligent frequency-specific side-chain compressor which carves a space for voices to sit nicely over music, etc.

    The RS124 compressor has a really nice smooth quality to it.

    The AMEK EQ 200 is an amazing EQ.

    Did you recently purchase any audio plugins? Which ones?

  • THS-MDM Microphone Decoupler

    THS-MDM Microphone Decoupler

    Sometimes vibrations from your desk or microphone stand can create loud disruptive jolting noises in your audio. That’s why Hook Studios created the THS-MDM Microphone Decoupler. Essentially it “disconnects” your microphone from whatever boom arm or stand you’re using as well as whatever surface it’s mounted on.

    From their website:

    • Our Patent Pending microphone mount mechanically decouples your microphone from direct contact between the microphone holder assembly and the microphone stand. The Hook Studios Mechanical Microphone Decoupler is easy to use and universally compatible with most OEM microphone clip holders and mounts that use standard 5/8″- 27 threads.
    • This product has been thoroughly field tested by independent audio engineers over a two year period. These tests revealed a marked reduction in “metallic” strike type impact sounds, as well as a reduction in vibration, unwanted floor noise, etc. In addition, the Decoupler may be used with an existing suspension mount to reduce vibration even further.
    • Critical studio listening tests using the MDM reveal increased clarity of the recorded source, especially with loud guitar cabinets. Considerable vibration of stands, hardware, etc. typically occurs in such situations, interfering with accurate harmonic overtone reproduction of the intended source. The MDM provides this decoupled suspension and vibration absorption regardless of the microphone’s direction or angle.
    • Two product sizes are currently available; the Large Size MD-175-70 Mechanical Decoupler (diameter: 1.75″) as pictured above on an AKG C12 swivel mount, and the Standard Size MD-150-70 Mechanical Decoupler (diameter: 1.50″), as pictured above with a black AKG 460 mic & 3rd party isolation mount.
    • The picture above also shows bottom and top views of the respective models.

  • Zoom F2 Field Recorder

    Zoom F2 Field Recorder

    This little recorder, the Zoom F2, comes with a lavalier microphone and can record in 32-bit resolution. It looks like it would be extremely handy for on-the-go recording.

    Zoom says: “32-Bit Float Technology in our smallest, lightest recorder ever. The F2 is a 32-bit/44.1kHz or 48kHz Field Recorder with LMF-2 Lavalier Microphone, Automatic Gain Adjustment, Included Software, and Accessories — $149. Also available with Bluetooth Control for $199.”

    Have you tried this recorder yet? I have not.

  • Michelle Levitt from Heil Sound – PES 207

    Michelle Levitt from Heil Sound – PES 207

    My guest is Michelle Levitt – Creative Marketing Director at Heil Sound and podcast producer. She has performed many roles in podcasting over the years including being CEO of her own podcast studio in Buffalo, NY!

    NOTE: Post-production on this episode was done by PES graduate Jesse McCune! Great job, Jesse!

    NOTE-2: On next week’s Daily Goody episode, I’ll be demonstrating and comparing the Heil PR30 and PR40!

    We discussed SO MUCH, including:

    • In-ear monitors: “Ultimate Ears” Capital Studio Reference
    • Allen and Heath ZED-10 mixer (uses no EQ, effects or pre-processing when recording)
    • iMac computer
    • Adobe Audition
    • Various Heil microphones including the PR30 and PR40
    • Pop filter: BSW Re-pop (fits the PR40 and PR30 nicely)
    • When demoing microphones at shows or online she doesn’t use any EQ or compression because she wants people to hear each microphones individual character.
    • Check out the presentation Michelle did titled Microphone Technology: Understanding Your Sound
    • Her advice to hosts who move around too much demonstrating bad mic technique: Put your chin or nose on the windscreen to always keep close to the mic. Also wear headphones so you can hear your volume change if/when you drift off-mic which will remind you to get back on mic.
    • Recently launched PR37 microphone — a dynamic mic for Live sound
    • Bob Heil doing Live sound for the Grateful Dead, The Who, early ZZ Top, etc. even though he came from a broadcast background.
    • Heil Sound started in the 60s as a music store — Ye Olde Music Shoppe (sp?)
    • Sony HD camera and running her local audio through Cam Link 4k thru HDMI cable

    Thanks for being a great guest and sharing so much with us, Michelle!

  • Fletcher-Munson Curves

    Fletcher-Munson Curves

    Your ears are amazing instruments. And at different volumes you actually hear slightly different frequency curves. A song’s frequency curve will sound different if you play it at a low volume as opposed to a high volume. Ever notice that when you monitor audio at a very low volume it sounds less clear with less high frequency clarity?

    “The Fletcher–Munson curves are one of many sets of equal-loudness contours for the human ear, determined experimentally by Harvey Fletcher and Wilden A. Munson, and reported in a 1933 paper entitled “Loudness, its definition, measurement and calculation” in the Journal of the Acoustical Society of America.” ~from Wikipedia.

  • Using Photopea.com To Create Episode Artwork for Free

    Using Photopea.com To Create Episode Artwork for Free

    When I started podcasting I had to figure out how to create and edit promo images because I didn’t own Photoshop or a similar app.

    I found this free website Photopea.com which has so many cool features and it’s easy for a photo-novice like me to create episode artwork and promo images and a lot more! After I create something I can save it in whatever format I need — .jpg or .png or even a .psd (Photoshop) document, and many more.

    I use Photopea.com almost every day and I love it.

    How do you create your promo images?

  • Where Do You Edit – in the Multitrack Session, or the Mixdown File, or Both?

    Where Do You Edit – in the Multitrack Session, or the Mixdown File, or Both?

    This questions has no wrong answers because you should work however you like to work.

    I used to do most of my editing on my mixed down file (using TwistedWave), after doing only a few edits in the multitrack session (mainly just separating sections where participants step on each other, etc.).

    But over the past 6 months I’m doing more than half of my editing in the multitrack session (using Reaper), and then I make some finer edits (mouthclicks, timing, top and tail, etc.) on the mixed down file (using TwistedWave).

    Fine-tune editing has always been much easier for me to do in a mono/stereo editor instead of a DAW.

    How about you?
