The recommended practices show how to eliminate large changes in sound levels between programs and between programs and commercials, the standards group said.
The Advanced Television Systems Committee has formally approved recommended practices for monitoring and controlling loudness of TV programming, the standards group announced today.
“High-quality multichannel sound is an important element of the digital television experience,” said ATSC President Mark Richer. “The new recommended practices provides the industry with uniform operating strategies that will optimize the audience listening experience by eliminating large changes in sound levels.”
The practices focus on audio measurement, production and post-production monitoring techniques and methods to effectively control loudness during the distribution and exchange of the programming.
In addition, they describe how to control differences in loudness between programming and commercials.
