Since 1989, Brent has been employed either by tech publications that cover audio, or directly in the audio industry. He has been actively involved in audio as a hobbyist and musician since about 1975. He can't say he's always right when it comes to audio (no one can), but his work rests on decades of experience, as detailed below:
Reviewed audio products as a freelancer for Wirecutter, Home Theater Review, SoundStage!, Sound & Vision, JazzTimes, About.com and others since 2008
Wrote and edited reviews of thousands of audio products as Editor-in-Chief of Home Entertainment (2002-2007), etown.com (1999-2000) and Home Theater (1995-1999), and senior editor of Video (1989-1994)
Measured performance of thousands of audio products using Audio Precision, Audiomatica CLIO, Linear X LMS, SoundCheck and Neutrik analyzers; and G.R.A.S. and B & K headphone measurement systems
Owns probably the largest collection of audio measurement gear of any freelance journalist
Conducted and/or participated in hundreds of multi-listener audio product comparison tests since 1991, and made these tests a regular part of Video, Home Theater and Sound & Vision magazines and Wirecutter
Participated in blind speaker comparison tests at Harman International, Paradigm and Canada’s National Research Council
Participated in audio measurement seminars conducted by Listen Inc., Audio Precision and G.R.A.S.
Created and mixed the multichannel and stereo test tones on Chesky Records’ SACD and DVD-Audio test discs
Performed, composed and recorded jazz off and on since 1979, most notably with the New York City jazz group Short Memory. He primarily plays double bass now, but has also gigged on Chapman Stick and ukulele. He hosts a weekly jazz jam session where musicians of all skill levels are invited, and he owns a drum kit, percussion instruments and various keyboards. Here are a few of his performances over the years:

Toured audio product factories in the U.S., Canada, Denmark, Germany, Switzerland, Britain and Japan
Been in way more anechoic chambers than he can remember and has witnessed, participated in and been instructed in audio measurement techniques by numerous manufacturers

Invented ButterSound, a real-time surround-sound active matrix encoder used in The Bride of Frank, a John Waters-style low-budget indie movie shown at the New York Underground Film Festival, Chicago Underground Film Festival, Yerba Buena Center for the Arts in San Francisco ("the most hilariously crass 89 minutes you've seen in aeons," said the San Francisco Bay Guardian) and film festivals in Italy, Switzerland and Britain. Here's a YouTube video from the DVD extras in which he demonstrates it (not safe for work!). This clip also features the ButterSound trailer, which Brent animated on a Commodore Amiga.
