Bryan Von Reuter is a Bay Area-based musician and audio professional who has forged a unique career path as an audio forensics examiner. Instead of the typical studio life, Bryan applies his deep knowledge of digital audio to the legal world, primarily working with criminal defense attorneys. His job involves analyzing, authenticating, and improving the intelligibility of audio recordings—from body cams to phone calls—that are submitted as evidence in court proceedings. It’s a fascinating field that combines a passion for sound with a commitment to justice and ensuring a fair process for the accused.
In This Episode
This week, we dive into a side of the audio world you’ve probably never considered with audio forensics examiner Bryan Von Reuter. He breaks down what it’s really like to analyze audio evidence for court cases, explaining the technical process of authenticating recordings and the difference between Hollywood voice identification and the real deal. Bryan drops some serious knowledge on the power of spectrograms, not just for forensics but as an indispensable creative tool for music production. We also get into the mind-blowing science of Electric Network Frequency (ENF)—how the 60-cycle hum from a power grid creates a unique, verifiable timestamp that can be used to detect edits. Beyond the tech, Bryan shares his journey from musician to examiner and offers a unique perspective on finding a fulfilling, sustainable audio career outside the studio.
