Santa Ana-based SRS Labs, a designer and manufacturer of audio equipment, is now selling its SRS HELM (Head-End Loudness Management), a new professional broadcast tool for Multichannel Video Programming Distribution, or broadcast cable, and broadcast operators around the world.
SRS’ HELM line of volume leveling tools includes HELM-RT for live feeds or Real-Time processing application and HELM-FB for offline, file-based work.
“Volume inconsistencies from program to program and program to commercial have plagued broadcast television since the dawn of the TV age and have only become more severe with the introduction of digital broadcasting,” said Alan Kraemer, chief technology officer for SRS Labs. “In the U.S., Congress took the initiative in 2010 to lay the foundation for putting an end to this common annoyance once and for all.”
HELM-RT was designed for real-time processing of live content during broadcast. The product not only analyzes linear broadcast feeds but also corrects any feeds that don’t comply with set house audio reference levels. HELM-RT was designed to minimize interference of the program stream except when audio or volume levels exceeding the pre-set reference levels is detected.
HELM-FB, the file-based and offline content processing tool, is designed to function in real-time and therefore is able to analyze an entire program much faster to determine loudness and make corrections. Created primarily for content creators and programmers, HELM-FB levels out volume fluctuations without changing the program’s range unless instructed by the user.
