Code for Ambisonics
Hi,
I have posted this three times to the flac-dev,
vorbis-dev, and ogg-dev mailing lists.
I wanted to see what code there was currently
to support Ambisonics. So I downloaded the
code from the xiph download page for
libogg-1.1.3, libvorbis-1.1.2, vorbis-tools-1.1.1
and flac-1.1.4, but wasn't able to find anything.
If it exists then I missed it, so could somebody
please point me to it.

5.1 surround channel coupling
>Yesterday I have finished writing the ambisonic pan filter for oggenc.
May I ask what this "pan filter" is?
I made some tentative suggestions for coupling Ambisonic B-format in a post
"Vorbis Ambisonic coupling" on 4feb07
I gather from the last monthly meeting, that some of you, including Monty, had problems with the phase behaviour of B-format.
Would anyone like a

Your proposed wording was:

follows SMPTE/ITU-R recommendations. The assignments are as follows:

Try using WavPack, http://www.wavpack.com/
This can losslessly compress 32-bit floating
point WAVE-EX files, and faithfully preserves
every chunk (which FLAC does not do). It is
also free.

Mapping = 1 Ambisonic Vorbis flag
Where can I find the Header file or whatever which specifies the "Mapping" flag.
In feb - apr 2007, there was a lot of discussion about Ambisonics and Monty kindly stated that
Mapping = 1 ; Denotes and Ambisonic file as opposed to = 0 which is 1 speaker/ 1 channel
Has this been written explicitly into the standard?
Which standard should I be looking at?

Tidy up of XiphWiki VorbisComment page
I have been tidying up the VorbisComment
page in the XiphWiki. The problem with it was
that it was a mixture of proposals and
discussion of those proposals. This made it
difficult for implementers to see what to
implement.
The problem section is:

This is a mess, and all I could do was add

More generally, in a stream in the Ogg file.
Codecs are streams, but so are things like
