TWiRT 811 - Advances in Audio Processing with Matt Levin and Hans van Zutphen

On *This Week in Radio Tech* Marianne Seidler, Matt Levin, and Hans van Zutphen join us for “Advances in Audio Processing”—Episode 811. Marianne adds some class, history, and great advice to the conversation while Matt and Hans explore the latest developments in StereoTool, including an optional approach that combines multiband A‑G‑C, compression, and limiting into a single processing stage. Hans also explains the ingenious RuleBreaker Clipper, which can deliver more than one dB of additional perceived loudness without increasing modulation or sacrificing audio dynamics, by continually optimizing the L-minus-R component of the FM multiplex signal. We also examine the growing worldwide adoption of MicroMPX and coding improvements that now deliver higher-quality performance at lower bit rates. If you care about competitive, efficient, and great-sounding FM audio, don’t miss this episode.

Marianne Seidler - Director of Business Development at Thimeo Audio Technology
Matt Levin - Senior Field Engineer at MaxxKonnect
Hans van Zutphen - CEO at Thimeo Audio Technology

TWiRT 810 - Speaker Design & Technology with Lars-Olof Janflod

Few studio monitors are as instantly recognizable—or as trusted—as those made by Genelec. On episode 810 of This Week in Radio Tech, our guest is Lars-Olof Janflod, Genelec’s Strategy Advisory Officer and a member of the company’s team since 1992. 

We trace Genelec’s story from its origins in Finland through the development of the distinctive, rugged monitor designs that have become familiar sights in studios and broadcast facilities worldwide. Lars-Olof explains the thinking behind Genelec’s unusual speaker designs and how the company has maintained its reputation for accuracy and reliability across three decades of technological change. 

We also explore today’s Smart Active Monitoring systems, which combine onboard DSP with automated calibration to optimize each loudspeaker for the room in which it is actually installed. 

It’s a fascinating conversation about loudspeaker engineering, acoustics, innovation, and the pursuit of truly trustworthy monitoring. Join us for TWiRT episode 810—listen or watch wherever you enjoy This Week in Radio Tech.

TWiRT 809 - Public Radio Studios in Knoxville with Tim Berry

Our guest on This Week in Radio Tech episode 809 is Tim Berry, Chief Engineer at WUOT-FM, the public radio station at the University of Tennessee in Knoxville. WUOT combines NPR news with classical and jazz music, much of it still played live from CDs and occasionally from the station’s enormous collection of LPs. 

Tim gives us a tour of the control room, performance area, technical center, and an extraordinary music library that also includes thousands of historic 78 RPM records. We’ll see one of Tennessee’s earliest Audio over IP installations, built around Axia Livewire technology and operating for about 15 years. 

Tim also maintains more than 20 analog and digital amateur radio repeater sites throughout East Tennessee. Join us for a fascinating look at preserving broadcasting’s rich history while planning the technical upgrades that will carry WUOT into the future.

TWiRT 808 - When the Chief Engineer Becomes CEO with Brett Gibson

Brett still has one foot firmly planted in the engineering world, even as he steps into the broader leadership responsibilities of running a radio ministry. That gives him a valuable perspective: he understands transmitters, studios, IP links, automation, remote sites, monitoring, redundancy, and after-hours recovery — but now he also has to think about budgets, staff, listeners, board expectations, and the mission of the network.

On this episode, Brett joins Kirk Harnack and co-host Chris Tarr, for a practical conversation about what it takes to build and maintain a reliable broadcast operation today. Brett shares how Voice of the Master’s technical plant has evolved over the years, what systems and standards have made the biggest difference, and how deeply IT has become integrated into modern radio engineering.

You’ll hear discussion about working at transmitter sites, improving reliability across multiple facilities, using technology wisely, securing remote access, documenting systems, and preparing for the inevitable late-night trouble call. Brett also talks about the transition from engineering leadership into the CEO role, and what broadcast engineers should learn if they want to grow beyond the rack room.

It’s a conversation about engineering, leadership, stewardship, and keeping radio stations operating smoothly and reliably — all on This Week in Radio Tech.

TWiRT 807 - Today's FM Radio Technology with William Harrison

William got his start in public radio in the 1990s at WAMU-FM, where computer work quickly expanded into audio and electronics. Since then, he’s worked with PBS, NPR, The Metropolitan Washington Ear, and a number of FM and TV broadcasters. He also chairs SBE Chapter 37 in D.C., serves on the Virginia SECC, sits on the board of the Association of Public Radio Engineers, and occasionally writes for Radio World.

In this episode, we talk about real-world FM engineering, including Capital Concerts fireworks show coordination, HD Radio timing and “ballgame” mode, receiver metadata behavior, liquid-cooled transmitters, HLS streaming for broadcast STL use, and dynamic range control in xHE-AAC.

Join us for a practical, wide-ranging conversation about broadcast engineering, public radio operations, and the listener experience on This Week in Radio Tech.
