Ensemble Designs Software Addresses CALM Act

The CALM (Commercial Advertisement Loudness Mitigation) Act, starting in December 2012, is legislation that will regulate the perceived loudness of TV commercials relative to the loudness of the TV program material they accompany. Ensemble Designs’ new LevelTrack software addresses compliance with the CALM Act.

LevelTrack AGC software for Avenue signal processing modules allows entry of a specific dialnorm number and an LKFS range to be maintained by the AGC of up to 16 audio channels. Individual channels can be grouped as a 5.1 surround group for LKFS averaging plus multiple stereo pair groupings, or individual channels, to which AGC is then applied. The AGC processing is applied across the entire dynamic range of the audio without using compression, leaving the the audio pristine, yet in compliance.
