opus - Jun 2016 - [PATCH] Add static bitrate allocation and force CELT-only for ambisonics encoding

This patch adds a static bitrate allocation for ambisonics encoded with the
multistream API. We allocate 4 bits to the mono channel (channel index 0)
 for every 3 bits allocated to other channels. The allocation is static
because it does not depend on the input audio.

This patch also forces the underlying encoders to use CELT only for
ambisonics.

Hi Michael,

Thanks for the patch. It's now merged in exp_lbr_tune, with one minor
change (please do not use C++-style // comments).

Cheers,

	Jean-Marc
