In Episode 318, audio engineering veterans Robert Scovill and Geoff McKinnon of EAW join the hosts to . discuss the evolution of adaptive sound systems, the unique aspects of EAW loudspeakers like Anya, and the real-world applications of adaptive technology in live sound. The conversation also touches on the challenges and misconceptions surrounding adaptive audio and the importance of technology training and education in the industry.

McKinnon is the senior director of engineering at EAW. With 10 patents spanning acoustics and system design, he has been a primary driver behind the company’s ADAPTive line and the new NTX and NT series. Leading the engineering team out of EAW’s new headquarters in Franklin, MA, he’s at the forefront of the use of DSP and physical design to solve some of the hardest problems in pro audio—basically making sure the signal is “perfect” before it leaves the box.

Scovill, who serves as senior live sound market specialist for EAW, is a 45-plus year veteran of professional concert sound and recording and has mixed over 4000 live events of every scale imaginable over the course of his storied career. His engineering and production talents have been enlisted by a “Who’s Who” of music Hall of Fame acts including Kenny Chesney, Tom Petty & The Heartbreakers, Matchbox Twenty, Jackson Browne, Rush, Def Leppard, Foreigner, Prince and numerous others.

Scovill’s body of live sound and recording work has garnered numerous industry accolades, including six TEC Awards, three PLSN Parnelli Awards, and multiple nominations for the CMA touring award, winning his first in 2022. He’s also been a multi-year nominee for Mobile Production’s “Top Dog” Award along with being an inaugural nominee for the Pensado Award for live sound excellence. In 2018 Robert was awarded the Lindenman Award for excellence in audio presentations at the Norwegian Sound Symposium. Since 2019, he’s served as a first call FOH mixer for television events such as THON, The Latin Grammy’s POTY, The MTV Video Music Awards and The Rock and Roll Hall of Fame Inductions, in which he received his first Emmy nomination in 2023.

In Episode 315, Sean and Andy get the lowdown on a relatively new live audio tool that took both NAMM and the online live audio community by storm over the last year as they talk with Devin Sheets, founder and owner of Alpha Labs, to learn all about De-Feedback. This episode is sponsored by Allen & Heath and RCF.

A much-talked-about plugin in live audio of 2025, there are lots of myths and misunderstandings, rave reviews and reticence about this new tool for fighting feedback, handling overly reverberant rooms, and dealing with noise in live reinforcement and broadcast environments, so we get it all straight from Devin, including a live demo of exactly what De-Feedback is capable of.

Devin Sheets, founder and owner of Alpha Labs, grew up in Salem, Oregon. His father Duane founded and owns Alpha Sound, a regional live audio production company, so Devin grew up in the busy environment of one of the largest PA rental and installation companies in the Pacific Northwest during the 1990s and 2000s.

After graduating from Azusa Pacific University with a degree in music, he and Duane turned the focus of the family business toward high-end corporate and house of worship work. Devin had his industry standard bag of tricks for fighting feedback in these environments, but felt that “the answer” had not yet arrived. After years of unfruitful communication with many leading audio manufacturers about the issue, he decided to try his hand at a custom approach involving AI software. After paying large amounts of his personal money to various coders around the world in an attempt to make something work, the team finally struck gold in mid 2024 with a novel AI model of their own making, using training data largely produced by Devin himself, on a computer they built in-house. He used the beta version throughout the year for his own shows and events, and installed it in several churches in the area.

By late 2024 there was pressure to begin selling the algorithm to the public, and so Alpha Labs was formed as a software partner company to Alpha Sound, a website launched, and sales of De-Feedback V1 began November 11 of that year. Within days, the plugin was being used on some of the biggest tours and events of the Christmas season. The software continues to be adopted by many of the world’s top engineers and venues, while Devin and his team concentrate most of their time and energy developing newer, better versions.

We've also uploaded a clip of Devin's demo of De-Feedback without our usual dynamics chain, for folks who want to listen to it as raw as possible, which you can download here: https://bit.ly/s2n-de-feedback (as a bonus, that clip is g-rated in terms of language, as well)

Sean and Andy start off 2026 with a bang, as live sound “renaissance man” Danny Abelson joins the show to discuss a wide range of bold positions, from how to prepare for a career in live audio to whether or not the quality of sound at shows today has kept up with the quality of the gear available to us to use at them. This episode is sponsored by Allen & Heath and RCF.

With a 50-plus-year career that started as a teenager working in New York City in the middle of “anything and everything” in the live music industry in the 70s, becoming friends and eventually in-laws with one of Clair’s first employees, as well as having one of the Taits as another in-law, if you saw Danny’s life story in a movie, you might not believe it’s real! From touring with the Eagles and Cheap Trick in the 70s to a theatre degree in the 80s and mixing NFL, MLB, and D1 sports, as well as long tenures on the manufacturing/distribution side of the industry for companies ranging from Turbosound to ATI mixing consoles, high-density Wi-Fi and ultrasonic signaling, and installations in venues as varied as Carnegie Hall, the Grand Ole Opry, and Lambeau Field, there’s quite literally nothing in the live sound field that Danny hasn’t done at some point!

Danny has written many articles published in Live Sound and FOH magazines, and currently writes the monthly “FOH-At-Large” column with close friend and writing partner Dave Natale for front of house. He is member of the Parnelli Awards Board of Advisors.

In Episode 310, the hosts welcome guest Tyler “Ty the Sound Guy” Davis, an experienced audio engineer with two decades in the industry. Born and raised in LA, Tyler started his audio journey two decades ago playing in bands, doing sound at DIY shows, recording bands in his garage, and mostly failing miserably at all the above! Through sheer unwillingness to accept that he wasn’t very good, he honed his skillset to come to the place where, 20 years later, he’s failing much less miserably! This episode is sponsored by Allen & Heath and RCF.

After touring for about 15 years, he started a family and focused on corporate, broadcast and remote production. While he still gets to mix music regularly, he’s enjoyed translating the years of concerts and touring to large-scale corporate events and broadcast environments.

Tyler shares insights from his career, discussing the shift from music touring to corporate and broadcast work, emphasizing the importance of continuous learning, networking, and being adaptable. He and the hosts also talk about the benefits of volunteering at churches for hands-on training, and the potential of having a mentor to guide one’s career. The conversation covers the importance of attitude, technical skills, and being a problem solver, all while maintaining a sense of humor in the ever-evolving world of audio engineering.

In Episode 309, the hosts turn over the reigns for a round of listener questions. They reached out to the Signal to Noise Community on Facebook and Discord to invite listeners to submit questions that they’re afraid to ask, or were afraid to ask when they were starting out in their career, and this week the hosts set out to answer the first handful of them. This episode is sponsored by Allen & Heath and RCF.

No topic was off-limits, from technical to interpersonal… Questions include strategies for overcoming introversion to excel in networking and finding more gigs, the importance of owning your mistakes (and not playing the blame game), practical advice for whether or not to bring personal equipment to jobs, improving mix confidence, virtual sound checks, balancing technical and soft/people skills, and more.

They also address broader issues such as effective sales strategies for project managers (and the technicians who love them), and the significance of value over price in client relations. The episode is filled with practical tips, industry insights, and personal anecdotes aimed at helping audio professionals succeed in their careers.

The hosts received plenty of questions; in fact, enough for another round in a future episode, but they’re still asking for more! If you’ve got a question you’ve always wanted to ask, email it to the at [email protected] or send a voice memo at http://speakpipe.com/s2n, and we may feature it in a future episode!)
