TWiRT 690 - Mics & Mic Processing with Cornelius Gould & Tom Ray

Search the web and you’ll find hundreds of articles videos - and thousands of opinions - on the best mics to use for radio and podcasting. One of our sponsors is Angry Audio, makers of two novel mic processors to improve and control the sound of two popular microphone families. Our longtime friend and colleague, Cornelius Gould, designed the audio processing algorithms behind these specific mic processors. “Corny” joins us to talk about this rather unique approach to mic processor design and implementation. Plus Tom Ray pops in to discuss microphone choices with Chris Tarr. Plenty of opinions and some solid advice!

Show Notes:
Cornelius Gould is also the founder & host of The Rocketry Show podcast.
The mic pre/processors for which Corny wrote the algorithms are the REbel & SMooth from Angry Audio
Tom Ray’s microphone is a PreSonus PX-1 condenser mic with a dbx 286s processor
Chris Tarr is liking his Electro-Voice RE20 with a RØDECaster Pro
Kirk is currently using a Sennheiser MKH 416-P48U3 with a PreSonus Revelator iO24

TWiRT 688 - I Can Fix DAP!

Over 50 years ago, Mike Dorrough introduced the Discriminate Audio Processor - the DAP 310. Broadcasters that cared about audio quality started buying and installing DAP310s to improve the audio quality of their stations. Five decades later these old audio processors are still in demand - as are services to supply parts and repairs. Randy Swaffer and Mike Phillips are two DAP310 enthusiasts - and they know all about repairing and aligning these classic units. Jordan Tuck also joins us to talk about refurbishing other broadcast gear, including a Continental Electronics FM transmitter and an A-6000 audio console.

TWiRT 687 - Can I Get You a Lift? with Jim Tiner

Most broadcasters either own towers or lease antenna space on them. But only the tallest towers are outfitted with elevators to bring workers and light tools up to desired working levels without spending half the day getting tired from climbing. Jim Tiner is CEO at Tower Elevators Systems. His company has built many towers - short, medium, and tall - and many of the tallest ones also have a custom-designed elevator system. This elevator technology is often applicable to other tall structures, such as bridge towers, smokestacks, and even the Statue of Liberty.  Jim Tiner presents his company’s fascinating story and tells us about unique elevator designs.

Show Notes:
