ATSC 3.0 To follow their progress, I suggest searching on the Web "ATSC 3.0." You will be directed to many sites including ATSC.org, where you can subscribe to their newsletter. From what I read, there is a plan to identify their goals by the end of 2015 with published recommendations sometime in 2016. If broadcast audio is of interest to you, I strongly suggest looking at all the sites shown where there are many proposed ideas for treating (messing with) audio on these sites. Hopefully, cooler heads will prevail. As usual, the mar- ket will ultimately determine their success. Progress of ATSC 3.0 and AES b y E d w a r d J . G r e e n e C A S This is meant as a follow-up to my previous article in the summer 2015 CAS Quarterly. That article attempted to give some history, past and present, to the problems in delivering audio as produced and mixed, properly to the viewer. The recommendations of ATSC 1.0, and later the Calm Act, successfully identified and helped address many viewer complaints. Also, the ATSC 1.0 recommendations are only for broadcast and not streaming for the Web. So the AES only recently assembled a distinguished study group on audio streaming loudness for the Web. By the time this Quarterly is published, there is likely to be further progress in both ATSC 3.0 and the AES streaming guidelines. To summarize, ATSC 3.0 will continue to be a work in progress and is meant as recommendations only for broadcasters while the AES loudness and streaming guidelines are only intended for network file playback on the Web. Recommendations for Loudness of Audio Streaming and Network File Playback Part 2: The Follow-Up AES Recommendations for Loudness of Audio Streaming and Network File Playback In a relatively short time frame, the AES study group has come up with version 1.0. Their editor, Bob Katz, has done a brilliant job of creating the document from the committees' writers to be adopted in New York by the AES Convention at the end of October. He has given permission to "liberally" include excerpts from that document. By the time the winter 2016 CAS Quarterly is published, the entire document should be available from AES.org. Here are their primary goals. 50 F A L L 2 0 1 5 C A S Q U A R T E R L Y
