Creative Community: Don't Tread On My Audio
Michael Grotticelli, Broadcast Engineering, 19-May-12

Writer Michael Grotticelli talks with Richard Cabot, founder and CTO of Qualis Audio, about how broadcasters are responding to CALM Act mandates and how this may impact audio quality. Topics include the effects of audio compressors and the pitfalls of an overly simplistic approach to measuring and managing loudness. They discuss the effect of downmixing on loudness and how it depends on the type of audio content.
