In practice, those defining such a format need not only to define the
file format itself, but also define and publish basic tools to
create/encode and decode, to a suitably wide range of representative
speaker arrangements; and of course to be able to confirm the whole
thing with listening tests. As well as expertise, that requires
considerable physical resources, to say nothing of the generation of
source material for test purposes. One way and another, it is an
expensive business!
The beautiful double blind listening-test proof (very) HOA format
maybe never will make it. An old WAVEEX based thing is also out of
discussion. How about a thing in between?
A quick and dirty "we can do it 'till april"-ambisonics that covers
already made .amb recordings up to third order and some additional
screen and LFE channels?
What about ambiX? Franz Zotter reading? :)
I think it doesn't work like < this >.
The basic discussion would be if a soundfield approach should be
included. After, you would define the details: Order, included direct
front channels /LFE channels, file format etc.
Why are you actually not reading what I was posting? One of the
requirements is "arbitrary" speaker layouts. Full stop. (There will be
some fixed layouts, I guess. But still.)
MPEG-H 3D Audio is envisaged to provide a highly immersive audio
experience to accompany the highly immersive experience provided by
MPEG-H HEVC. Such an immersive listening experience will be realized
by the rendering of a realistic and compelling 3D audio scene either
by using a large number of loudspeakers, such as for 22.2 channel
audio programs, or by using headphones supporting binauralization.
Key issues to be addressed are a compact and bit-efficient
representation of multi-channel audio programs and the ability to
flexibly render an audio program to an arbitrary number of
loudspeakers with arbitrary configurations. 3D Audio support via
headphones is also a key capability in order to deliver an immersive
experience for users of mobile devices.
A final CfP will be issued at the 103rd meeting in January 2012,
Don't speculate too much around, just < do read >.
Best,

P.S.: I know why I copy and paste such things.
Dolby Atmos also covers arbitrary speaker layouts, BTW. We are talking
about the reality, which is already being implemented.
