God speed to Etienne and his work. He takes an interesting condition
precedent and builds on it.
There is a more general solution that has attracted wide support. (see below).
For compression (which seems to be the topic here) that uses WavPack. In the
latest release (WavPack 4.69 beta) nearly all the 'barriers' have been
lifted, the one remaining one is for WavPack to pack/unpack CAF/PCM files
(not that remote from packing/unpacking WAV/PCM files). That is 'on the
table' and will hopefully be in the next release (see the paper below).
Michael.
"A Standard for Interchange of Ambisonic Signal Sets: Including a file
standard with metadata."
(Compression is in section 5, page 4.)
