On December 15, 2010, the CALM Act was enacted into law. Subsequently, this past December the Federal Communications Commission (FCC) adapted regulations as to controlling the relative loudness of commercials based on ATSC Recommended Practices A/85 – Techniques for Establishing and Maintaining Audio Loudness for Digital Television.

NY SMPTE Program

This program will provide a brief synopsis as to how loudness should be measured and how consistent loudness levels can be maintained using the practices described in ATSC A/85 and then segue into the FCC parameters and mandates that will be required by broadcasters and media content providers by December 13, 2012.
