George Whittam - I call him “Engineer to the Stars” - is back on TWiRT! This time he’s brought photos of home studio design and construction. George talks about some challenges in the layout and building of these home Voice-Over (VO) studios. We also get George’s opinion on headphones and microphones, and a look at what makes the Apollo audio interfaces so sophisticated; it’s a lot more than I had imagined. Kirk Harnack interviews George Whittam on this episode of TWiRT!

Show Notes:

* George’s web site - GeorgeThe.Tech - with Tools, Tips, and Testimonials for VO spaces

* George has always like the Beyerdynamic DT 770 PRO headphones

* George speaks highly of the Austrian Audio Hi-X15 headphones

* When asked about wireless noise-canceling headphones, the 1MORE Sonoflow came up

* Handheld mics were discussed and George likes the Sennheiser e965

* Universal Audio Apollo Audio Interfaces

Ready to learn some surprising facts about audio processing? David Reaves - known by many for the Ariane audio processor - is guest! We're talking, of course, about the famous Ariane audio processor, but also the CBS Audimax and Volumax. Did you know the Audimax had a "memory module" that was key to its “intelligent” audio leveling action? Pretty slick for early 1960's design!

Show Notes:

* Recent projects from David are on his web site, DavidReaves3.com

* CBS Audimax and Volumax circa 1964 from Preservation Sound

Frank Foti is well known within the broadcasting industry for his digital audio processing innovations. Those of us who know Frank personally know that he is a huge fan of 5.1 audio recordings, and that he has often lamented the scarcity of available material. But unlike the rest of us, Frank actually has the skills to do something about it. He’s been developing DejaVu for several years and says it’s finally ready. Frank explains how his artistic upmixing technologies led him to Abbey Road studios in London, and how this tech is now easily available on several platforms.

Cornelius Gould began nearly 40 years ago considering audio processing and its effect on how we perceive music and voice. His “Chameleon” audio processing algorithms began with analog circuits, but are now fully emulated and perfected in Digital Signal Processing (DSP). What makes audio more pleasing to our ears and brains? What might a psychoacoustic expert say about the treatment of audio so we hear and appreciate it more enjoyably? Chris Tarr joins Kirk Harnack to discuss these topics and questions on today’s TWiRT.

Like many of us broadcast engineers, Sascha Ludwig builds and maintains somewhat traditional broadcast studios while implementing server-based virtualized solutions as well. Sascha is based in Germany where the talent appreciates traditional hardware user interfaces. But he’s implementing more of today’s technology for these content creators. As a software developer, he maintains and update the OnAirScreen software package appearing in radio control rooms everywhere. Chris Tarr joins us for a good discussion and comparison of some German engineering and how we’re doing broadcast engineering in the US.

Show Notes:

* OnAirScreen from AstraStudios

* OnAirScreen on GitHub (for those who know what to do)

* Sascha uses Zabbix software to monitor computers and applications

Hearing dialog on some TV shows and many movies broadcast on TV is a problem. Why is dialog often hard to hear? Radio doesn’t have this problem. And TV typically didn’t until we went digital with DTV and 5.1 audio. Ken Tankel is Kirk’s go-to TV audio specialist. Ken worked for years in radio major market radio, so he understands audio processing. But, TV audio is markedly different, with different goals, targets, and formats. But we’d still like to understand the dialog! Ken walks us through some similarities and differences in TV and radio audio, and describes TV’s audio problems with some possible solutions.

Show notes:

* The USA’s CALM Act is about Loud Commercials

* Pro Tools Expert article on Loudness - Good Summary

* “CALM Before the Storm” - blog post on CALM compliance

* Kirk suggested that 5.1 mixes be checked in stereo with Auratone speakers

Some technical advice is timeless. Other tech advice changes with the times. Such is the case with FM transmitter sites. Now more than ever we broadcast engineers need to apply the right safeguards and approaches at today’s FM transmitter sites. Situated under tall lightning “attractors” - otherwise known as “towers” - FM transmitter sites need a mix of time-tested design care and contemporary precautions. Hal Kneller is a 40 year veteran of transmitter sites, and his Florida home provides plenty of experience with lightning protection, whether the equipment is old or new. 

Show notes:

* Xenirad Broadcast Engineering - web page with ¼ wave shorting stub demo video

* Hal mentioned the CyberPower ATS PDU 44004

* Kirk Mentioned the Henry Engineering Failsafe UPS Power Switcher

* Nautel white paper on Lightning Protection for Radio Transmitter Stations

Pierre Lonewolf’s career journey that led him to Kotzebue, Alaska in the early 1980s. You can’t get much farther away from major population bases than northern Alaska. Kotzebue, population 3,283, sits on a sand spit of Alaska’s Arctic west coast just across the Chukchi and Bering Seas and several hundred miles from the Russian eastern frontier. It’s a scenic but scarcely populated place that features abundant wildlife like caribou and moose and bear. Pierre Lonewolf, CSRE, CNT, manages engineering services at KOTZ(AM) and KINU(FM) plus a network of FM translators and low-power FMs serving tiny villages. [Excerpted from an article by Randy Stine.] Pierre joins Chris Tarr and Kirk Harnack for a lively discussion of radio engineering in this remote Alaskan village.

Show notes:

* Radio Heritage Foundation article about Pierre Lonewolf by Randy Stine

* Pierre and Chris mentioned the Inovonics IRM610, Internet Radio Monitor

“Aggressive Neglect” sounds like a great name for an Alt Rock band, but it’s actually one of Dennis Sloatman’s pet peeves. Petrified hamburger leftovers in the wiring chases is another. But he would rather construct new, reliable, yet simple broadcast systems than complain about poor work that preceded him. From continuing education to SNMP-monitored systems to small, medium and very large markets, Dennis Sloatman is the thoughtful engineer who plans the work and then works the plan. Let’s get wiser in our broadcast engineering skills by spending an hour with the top-shelf broadcaster.
