As everyone knows, the First Rule of Fight Club is that you don’t talk about the Committee Work of the Society of Motion Pictures and Television Engineers. So, although Atmos Sound has been around since shortly after the CinemaCon 2012 introduction, with about 4,000 installations by now, and DTS showed their iteration of the Open Source MDA Object Oriented sound, DTS:X, at CinemaCon 2015…and Barco bought the Iosonno rights up about that same time to augment the Auro system with object oriented sound …one heard nary a word out of the committee halls of SMPTE about the known Immersive Audio objective: a single standard format for immersive sound so that any mix will play in any theater, regardless of the manufacturer of the compliant rendering system it was playing on.
And now that has changed: The first 3 SMPTE documents have been released toward that immersive effort. They won’t be interesting to anyone who isn’t making a rendering device since they merely (merely, the editor scoffs) describe the bitstream, establishes the metadata, and defines the names of the sound field groups and channels that make up an immersive track.
