Shawn Kitchen – PES 131
My guest is Shawn Kitchen – host of the Northwest Corner Podcast. He lives in Spartanburg, SC, was formerly trained in radio and tv, and is currently records his show using a Live format to reduce post-production time.
We discussed his production workflow and equipment in detail, including:
- Using a Kindle tablet to play sound FX
- Riding faders Live
- Mixer has one knob compression on each channel
- Mic technique
- Using subgroups: Voices to one group, music to another group, then record each group separately on his Zoom H6
- Chris’s Compression Dynamics plugin within Audacity
- Noise reduction in Audacity by creating and using a custom noise profile (he removes 14 or 15 dB of noise!)
- Record everything 24 bit / 44.1 kHz
- Soundcloud
- Behringer X2222USB analog mixer
- Behringer UMC404HD interface
- Tascam DR-40 field recorder
- Zoom H6 field recorder
- Behringer XM8500 dynamic mics
- MXL FR-355K lavalier mics
- Audacity
- Hindenburg
- Soundpad app for Android on Kindle Fire 8HD tablet
- iRig 2 instrument interface
- Behringer headphone distribution amp and headphones (for up to 8 people)
- All post-production done in-house on Dell desktop with Core I5 processor using primarily Audacity, but have been using Hindenburg more frequently in recent time. Pre-recorded music tracks (except show theme) are separated into new tracks. All vocals are run through a combination of soft limiter, compression, and then amplification to -1.0 dB. Noise reduction is done at the *end* of all other processing, using a 5-second segment of silence with all mics open at the beginning of each recording session. I’ve found that applying noise reduction at the end yields us with the clearest results.
Thanks for being a great guest, Shawn!

Brodie Brazil of NBC Sports California – PES 121
Brodie Brazil is here! He’s a TV broadcaster and hosts the Oakland A’s & San Jose Sharks Pre/Postgame Live on NBC Sports California. Check out his YouTube. He has won 13 Regional Emmy Awards and nominated for 32!
Also check out his podcast, Brodie Brazil.
We discussed a ton, including:
- Packing blankets and rug in his home studio
- Mics: TLM103, SM7B through Fethead, RE320’s, MD46’s, HMD26
- Mixer: Soundcraft 12 MTK
- Channel strips: dbx 286’s
- Remote interface: UMC202HD
- Recorders: Zoom H5 & H6
- Computer: MacBook Pro running Audition (old version!)
- Headphones: Beyerdynamic DT-770’s
- On-location: Zoom H6 w/ two RE320’s
- TV mic: Sennheiser MD-46
- Because I do a lot of live streaming – need most of my processing (comp, EQ, de-essing, gate) baked in. So I have that for both the Neumann and Shure mics. I do add a little post-processing for podcasts and YouTube videos with just some light compression… normalization, then clip gain matching to -16 lufs.
- Everything exported to .wav for videos and editing. eventually .mp3 for podcasting to… Soundcloud(!) I know, but it works best for me (I can explain).
Thanks for hanging with us, Brodie!

MP3 vs. AAC (.m4a) with Allan Tépper – PES 120
Great discussion with Allan Tépper. He is the host of Beyond Podcasting, as well as a a Pro Audio/Video specialist, tech journalist, broadcaster, author and consultant. (and my previous guest on episode 74)
*DISCLAIMER: We are not advocating for anyone to switch from MP3 to AAC (.m4a). If you’re contemplating it, please do more research and decide for yourself.
We discussed many aspects of MP3 vs. AAC (.m4a):
Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO/IEC in 11172-3 (MPEG-1 Audio) and 13818-3 (MPEG-2 Audio)
The widespread reluctance to even THINK about publishing podcast episodes in any other format than MP3.
.m4a is the most common extension, but not the only extension, used for AAC.
Sound quality: AAC sounds better than MP3 especially when encoded at lower bitrates. This means that your final episode file can be smaller in size and still sound as good or better than MP3.
Chris’s experience: “When I convert my .WAV file to MP3 using iZotope RX 7, the resultant MP3 is 0.4 LUFS lower in volume than the original .WAV. Whereas when I convert to .m4a the resulting LUFS level of the .m4a is exactly the same as the original .WAV file. Interesting…”
Compatibility with ad insertion platforms: Rob Greenlee says, “Hey Chris, Most of the platforms that utilized dynamic ad insertion technology, oftentimes require MP3 files only.”
TPES episodes that published in .m4a:
ID3 Tags: Bryan Entzminger says, “I did a test with an episode. I didn’t like that Libsyn didn’t pull the id3 info from the file (because it’s not an MP3) but that’s not a really big deal.”
A few popular shows that use .m4a files:
- Podnews (James Cridland’s show, @ 44.1 kHz so far)
- 60 Sec Torah Byte (Zalman Levin / Podbean 44.1 kHz so far)
- Morning Mantra (Coach MK / Anchor)
- BeyondPodcasting (Allan Tépper’s show, @ 48 kHz)
- Podcast Engineering Show (Barry and Chris’s show, @ 48 kHz)
Technical analysis of top podcasts – James Cridland’s post looking at bitrate. LUFS, mono/stereo, etc.:
https://podnews.net/article/podcast-analysis?utm_source=podnews.net&utm_medium=email&utm_campaign=podnews.net:2019-01-17AAC’s improvements over MP3 (from Wikipedia)
Blind tests in the late 1990s showed that AAC demonstrated greater sound quality and transparency than MP3 for files coded at the same bit rate.
Improvements include:
- more sample rates (from 8 to 96 kHz) than MP3 (16 to 48 kHz)
- up to 48 channels (MP3 supports up to two channels in MPEG-1 mode and up to 5.1 channels in MPEG-2 mode)
- higher coding efficiency for stationary signals (AAC uses a blocksize of 1024 or 960 samples, allowing more efficient coding than MP3’s 576 sample blocks)
- higher coding accuracy for transient signals (AAC uses a blocksize of 128 or 120 samples, allowing more accurate coding than MP3’s 192 sample blocks)
- much better handling of audio frequencies above 16 kHz
- more flexible joint stereo (different methods can be used in different frequency ranges)
Encoding:
*NOTE: NONE of these lists is exhaustive. We did not investigate every single program in existence 😉
Programs that can encode .m4a files:
- iTunes
- Fission (Mac only. Also can tag and create chapters. Allan Tépper’s favorite 1-track audio editor for Mac. Unique because it can also edit lossy formats without generation loss. Can’t save tag data but can copy and paste tag data. Chris was confused because Fission’s tag data doesn’t have a ‘Copyright’ field.)
- Hindenburg Journalist Pro (also can tag and create chapters. Allan Tépper’s favorite multitrack audio editor for conventional computers)
- TwistedWave (Mac, PC and online. Good program but no playback speed adjustment!)
- Amadeus Pro
- 3rd Party Encoder Plugins (Paul Figgiani suggested Sonnox’s Codec Toolbox ~47 USD and Pro Codec ~400 USD.)
Programs that encode MP3s using the Fraunhofer MP3 Encoder algorithm:
- Adobe Audition
- iTunes (Source: Cliff Ravenscraft on October 27, 2010)
- Windows Media Player (Source: Richard Farrar)
Programs for which you can buy an optional Fraunhofer plugin for US$339.15
- Pro Tools
- Logic
- Cubase
- Nuendo
- Sequoia
- Wavelab
Programs that DON’T use the Fraunhofer MP3 Encoder algorithm:
- Hindenburg
- Reaper
- iZotope RX
Players
Compatibility with players and apps: .m4a files are compatible with all podcast players we could find.
Thanks for sharing so much great info, Allan!

Bryan Entzminger – PES 119
Great conversation with Bryan Entzminger, host of Engaging Missions and podcast engineer/editor.
We discuss his podcast production and quite a bit about his preferred DAW which he is quite skilled in using: Hindenburg Journalist Pro.
Here is Bryan’s Live Demonstration of Hindenburg Journalist Pro, and here’s a 90-day free trial of Hindenburg Journalist Pro.
Here are Bryan’s production details:
- Electro-Voice RE320
- Rolls cough switch
- Sound Devices MixPre-3
- For remote internet calls, I use a second computer (an old Dell) into the line in for the MixPre-3 using a hardware mix-minus in the MixPre
- I record 2 tracks right onto the SD card in the MixPre. I also run 2 tracks via USB into my MacBook Pro and record into Hindenburg Journalist Pro
- Voice profiler in Hindenburg can create custom profiles!
- For editing, I use Hindenburg Journalist Pro along with iZotope RX7 for audio restoration and Ozone 7 for mastering and a variety of Waves and other plugins depending on the need. I mix and edit in multitrack mode, export to WAV fully mastered but not normalized to -16/-19.
- I then bring that mastered file back into Hindenburg to level using the loudness matching and either convert to MP3 using Hindenburg or RX7. If I use Hindenburg, I’ll also apply the id3 tags and upload right to Libsyn from there.
Also, Bryan got back to me about the Hindenburg auto-leveling feature that we discussed in the episode: “I did several checks with the auto-level with effects and it appears my original assumption was correct. The auto-level is at the “region” (clip) level upon input – prior to ANY processing within Hindenburg.“
Thanks for sharing so much great info, Bryan!
