As for home use, how would that be any different than the situation now with Dolby, DTS, Audyssey et al?
Because Dolby TrueHD and DTS Master Audio on Blu-ray offer lossless technologies that are both audio compression codecs serving the same, exact purpose: encoding and then decoding up to eight discrete channels of PCM audio (much like a ZIP file).
Dolby Atmos and DTS MDA use different
mixing software technologies and standards for object-based soundtracks... so if there were these two formats available for commercial theaters, you'd have to mix the 3D audio soundtrack TWICE (in this instance 3D means x, y, and z axis steering for height, width, depth... not just sounds existing on a linear plane).
If there was an open source solution that also allowed for object-based 3D mixing (or "rendering")... you'd only have to mix ONCE, and then down-convert that metadata controlled bitstream to any and all current codecs.
IMHO, any potential format could follow Atmos' lead and allow for up to 64 "channels" of full-frequency, 24 bit lossless audio data for the "renderer" to ingest and position in accordance to the speaker layout chosen.Edited by Dan Hitchman - 4/17/13 at 4:57pm
