AES Session Explains Loudness Recommendations

Document aims at audio streaming and on-demand distribution

A session of the AES Fall Online Convention this week will explain new recommendations about streaming loudness.

“Internet audio streaming and on-demand file playback have become major sources of media delivery, affecting the ways that audio is recorded, mixed, post-produced and delivered,” the organization noted in a session summary.

“Excessive loudness compromises quality, inconsistent loudness annoys listeners. To resolve these issues, the AES Technical Committee for Broadcast and Online Delivery has created recommended guidelines for establishing and implementing an effective Distribution Loudness for streaming and on-demand audio file playback. This session will have members of the committee discussing the recently released TD1008 Recommendations for Loudness of Internet Audio Streaming and On-Demand Distribution.”
