[Vorbis-dev] 5.1 surround channel coupling

improve Vorbis codec, but the question is whether they want to.
Vorbis' surround application stands in its place from at least five
years; there were no common tools to easily encode/decode Ambisonics
till now.

Thanks Sebastien.

Does this mean there is an existing B-format to Vorbis encoder?

And a Vorbis to B-format decoder?

How do I find what design decisions were made in this?

Particularly the frequency banding and "phase" model used.

My interest is that the time is now ripe for Ambisonics to adopt a good compressed format.  Vorbis is the obvious candidate.

I was hoping to become a Vorbis guru and extend Vorbis to do Ambisonics properly.  It's not as complicated as I originally envisaged.  But I need more info.
