Digital television audio loudness continues to be a troublesome problem for large and small networks, local stations, cable and satellite operators and other Multichannel Video Program Distributors (MVPD’s).  The vast improvement in audio capability of the ATSC AC-3 audio system over analog TV has brought with it an increase dynamic range and metadata controlled level scaling.  This transition created a culture change in audio loudness management that at first, many broadcasters were ill equipped and unprepared to adapt to.

Unfortunately, this situation continues to result in consistent audio challenges for the broadcaster, advertiser, programmer and MVPD. Ineffective DTV loudness management to date has lead to widespread viewer complaints and the looming threat of legislative and regulatory action to control the problem.

Ahead of these issues, with an initiative starting in April of 2007 and against this backdrop, the Advanced Television System’s Committee (ATSC) released Recommended Practice A/85: Techniques for Establishing and Maintaining Audio Loudness for Digital Television. The complete document is available here.

Created by ATSC S6-3, a group of industry experts with real-world experience in DTV audio, this paper focuses directly on loudness management recommendations for the broadcaster, operator, content creator and MVPDs.

The DTV Audio Group has invited members of S6-3 to discuss the key aspects of this document with broadcast engineering and operations managers as well as DTV technologists to discuss unique, workable applications of good loudness practice.
