In the second part of Andy’s conversation with Cody Heimann of Sound Devices (part one is here), the duo rolls up their sleeves and goes deep on the company’s Astral wireless platform that offers 32 channels in a single rack-unit, Optocore integration, and a handheld transmitter that can take almost any capsule on the market without any additional adapters, there’s a lot to discuss. This episode is sponsored by Allen & Heath and RCF.

Episode 290 goes all in on wireless as Andy is joined by Cody Heimann, RF applications engineer at Sound Devices as well as a veteran RF coordinator for large-scale events. In the first of two episodes, he talks about how his career grew and led to finding a niche as an RF coordinator for events and clients such as Coachella, New Year’s Eve in Times Square, and some of the largest corporate events and conventions in the world. This episode is sponsored by Allen & Heath and RCF.

In a wide-ranging conversation, Cody shares tips and advice for handling large events, making wise choices about compromises to fit hundreds of channels of RF into tight spaces, and much more!

After starting his career as an audio assistant, he became a stage tech and patch master, moving through the ranks to monitor and front of house engineer, PA tech, and production manager. He’s been involved in all things audio, which has allowed him to build a diverse portfolio in troubleshooting, technical skills and client relationships.

Now, as an RF applications engineer, he’s definitely no stranger to being agile and working in different mediums of the industry. In April of 2024, Cody joined the RF Applications Team at Sound Devices where he largely works largely in product development, technical support, education, and large-scale and complex deployments of the company’s Astral wireless systems.

Cody loves fitness and the outdoors; he was a part-owner of Music City Boxing in Nashville, met his wife rock climbing as well as an avid motorcycle enthusiast and self-proclaimed “once upon a time drummer.” It’s no doubt that music has been a passion of his since his youth and he loves being able to help continue to be a small part in the big shows!

The Signal To Noise Podcast on ProSoundWeb is co-hosted by pro audio veterans Andy Leviss and Sean Walker.

“Spatial” and “immersive” audio are buzzwords that we seem unable to escape in today’s world of live sound, but what do they actually mean and how do we use them — if we even should at all? Theatre sound designer Nat Houle joins the show in Episode 289 to provide a “manufacturer-agnostic” take on the topic, benefits and limitations, and much more. This episode is sponsored by Allen & Heath and RCF.

Houle, a 2025 USITT Rising Star winner for sound design, works as a designer and associate across the U.S. Last year, she launched a website, NMH Spatial, aimed at introducing folks to the benefits of spatial audio, in addition to shedding light on a number of common myths and misconceptions about the technology and how it can enable and impact your art.

Episode 288 Transcript

Veteran mix engineer Wayne Pauley returns the show in Episode 287 to talk with the hosts about his experience mixing RCF’s Ultimate Jam Night showcase at NAMM, and doing it in the inimitable “Wayne Pauley style” — in other words, as analog as possible! This episode is sponsored by Allen & Heath and RCF.

Wayne also talks about touring with an RCF TT+ Audio PA as well as his love for ATI Paragon II consoles, sharing the story of his one-of-a-kind custom half-desk Paragon made by FOH engineer and analog console whisperer Chris Mitchell. In addition, he offers some first-class advice on how to make your reverbs sound perfectly subtle, and much more!

In Episode 286, Sean and Andy continue their look at stepping up from smaller shows with a dive into larger intercom platforms and a look at life past four-channel analog systems. This episode is sponsored by Allen & Heath and RCF.

Drawing from his work programming intercom systems for large scale corporate and broadcast events, including network upfronts, professional wrestling matches, and the recent SNL50 Homecoming Concert at Radio City Music Hall, Andy shares a brand-agnostic look at some tips and tricks for making the most of the options digital intercom systems offer — how a nearly infinite pool of private channels is helpful (and when it’s not!), making sure that as a comms programmer, the first goal is to make everybody else’s show run smoother, and why the most important tool a programmer can have on a show site is almost certainly not what you’d guess!

In Episode 285, the hosts are joined by Tal Kocen and Dave Friesema, founders of brand-new in-ear monitor maker Dark Matter Audio Labs. Sean and Andy were impressed with their IEMs when the company launched at NAMM a couple weeks ago, and knew they had to have the duo on to tell their story. This episode is sponsored by Allen & Heath and RCF.

Tal and Dave detail their history in the live audio and IEM manufacturing worlds, and the journey that led to them branching off on their own to start Dark Matter Audio Labs. They also dig deep into the design and mechanics of IEMs, explaining a lot of what goes into making objectively and subjectively good IEMs, the surprisingly tricky task of making generic-fit demo models of custom IEMs, why the frequency response of IEMs might surprise you, and so much more!

As a special bonus for listeners, Tal and Dave are offering a 10 percent discount off any of their in-ears to listeners…just use the discount code “SignalToNoise” when you check out! Also, if any listeners or their artists are interested in joining the DMA Labs artist program, reach out to Rachelle, their artist relations human, at [email protected], and tell her you heard about them on Signal to Noise!

Picking up where they left off in Episode 282, Sean and Andy dig deeper into the “hows and whys” of wireless system frequency coordination, addressing issues such as whether it’s ever OK to just scan on the receiver, an overview of the differences between the Shure Wireless Workbench and SoundBase Coord platforms, the reasons why it’s always a good idea to do your own frequency scan with an analyzer, which inexpensive analyzers you can trust (and which you can’t — and why!), and more.
