The national and international audio and broadcast industry has heightened awareness about loudness levels in audio and the need to achieve consistency between programs. The Advanced Television Systems Committee (ATSC) has developed a loudness standard for television in order to comply with the Federal Commercial Advertisement Loudness Mitigation (CALM) Act which regulates the audio of TV commercials.
The International Telecommunication Union (ITU), European Broadcasting Union (EBU) and Audio Engineering Society (AES) also have loudness recommendations for all broadcasters. In meeting these standards, there’s also a movement away from using peak program meters to measure audio levels and a trend toward using instruments and processes that measure audio loudness.
The Public Radio Satellite System (PRSS) staff is seeking to improve its understanding of this issue across the PRSS. Specifically, the PRSS is examining inconsistencies in loudness levels among PRSS-distributed programs. We’re very interested in the views of broadcast engineers and producers on these issues and want your input via a short survey. The survey – which should take 10-15 minutes to complete – seeks to understand the situation at your workplace.
The survey results will feed into recommendations to be made this fall to the Distribution/Interconnection Committee of the NPR Board for the role that PRSS plays in assisting public radio achieving consistency in audio levels.
Your input is critical and valued highly.
