CALM audio loudness monitors
The Commercial Advertisement Loudness Mitigation (CALM) Act requires U.S. TV commercials not to exceed dialnorms by more than a few LKFS units. StreamScope CALM monitors help meet this challenge.
Ensure CALM Act compliance
StreamScope CALM monitors analyze audio streams for ATSC A/85, ITU-R BS.1770-3, and CALM Act compliance. By locating loudness problems, these monitors improve DTV audio quality and increase customer satisfaction and retention.
