Spatial/Atmos on FLAC?
Hi,
are there any plans for FLAC to implement spatial audio? Or maybe Atmos on FLAC?

Multichannel, usage & players?
Hello to the list, and please forgive me if this has already been asked before.
(I am new here, you see)
The question is really simple:
Can I use FLAC to create multichannel files, ranging from 3-channel LCR, through Quad, 4.1 to 5.1 and possibly (later) above?
The projects details are essentially this:
DVD-Audio, containing MLP Lossless in stereo & surround/multichannel.

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

5.1 surround channel coupling
It obviously would be nice to have such a mode available, for e.g. DVD audio
compression. Apparently, the list doesn''t tell me too much about it. My
questions are:
1. What is the current status of the 5.1 channel coupling in Vorbis?
2. If I''ll be interested in participation in its development, what is the
recommended reading?

Calling for 5.1 Mastering experience! (vorbis ambisonics and 5.1)
I've been doing a fair amount of work with Vorbis support for Ambisonics,
which seems to be going along nicely. It seems that there is signifant
interest in coding 5.1 material with Vorbis esp as tarkin becomes more
complete, so I've decided to take a break from pure ambisonic work to look
into this.

OggPCM2 : chunked vs interleaved data
I made a few updates to OggPCM2 http://wiki.xiph.org/index.php/OggPCM2
reflecting the latest discussions. Could everyone have a look at it and
see if they agree. Otherwise, what do you feel should be changed? Anyone
wants to speak in support of chunked PCM?
For all those that are just tired of this mess like me, please express
yourself in the new spec I created: OggPCM3

Decoding for ambisonic Ogg audiob
The prospect of people actually putting B-format audio (via the panner
or directly input) into Ogg/Vorbis brings an interesting challenge:
What do we do with the audio after decoding it?
The following sane options exist:
A) Simply output the B-format audio
B) Produce a downmix
1) Mono.
2) Stereo blumlein crossed pairs
3) Stereo UHJ
4) binaural
C) Produce speaker feeds

Define 6.1 and 7.1 channel mappings
I vote for documenting the --channel-map option in the --help
I don't like the idea of rejecting a multichannel file merely for
mapping, so there should be a documented option plus an error message
pointing to the option. This should compare to the WAVE and AIFF
errors where the utility suggests to the user how to get the file
converted safely.

True surround sound for Ogg -- a proposal
Hi everyone,
Over the last two weeks or so, I've been thinking about how to add surround
sound to Ogg -- and more than that, to do it in the best way possible. With
this in mind, I started considering using Ambisonic surround sound. The
advantages of this format are considerable:
a) It was developed in the early to mid '70s, so the patents should
be expired by now.

Multichannel vorbis.
Hi.
I have two CDs that the artists inteded for simultaneous listening. They
even provide instructions on how to start two CD players with the
minimal time shift.
(for those interested - the CDs are Neurosis/Times Of Grace and Tribes
Of Neurot/Grace)
I've heard that Vorbis can encode multiple streams. I've already encoded
both albums into regular 2-channel .ogg files.

Professional surround mastering is delivered on very specific media,
and FLAC is not an option (to my knowledge).
I use FLAC for archival of original

A possible use for multichannel ogg files!
Hi,
Has anyone thought about using the multichannel format as a way of
distributing "musician minus one" files?
Eh? I hear you ask. Ok. Basically these are multitrack files but you can
mute the solo track so you, the musician, can practice against the other
"players". You can buy CD's of this nature, but of course, the solo
instrument is on one channel and the others on

Multi-channel support
Hi All,
Are multi-channel (more than 2) formats fully supported in the OggVorbis specification ? I couldn't
find any information about multi-channel support on xiph.org. I've used 'oggdropXPd' to encode a
5.1 wavefile and the Xiph OggVorbis libraries (vorbisfile.dll) to decode the file successfully,
however the order of the channel interleaving is different to the original wave
