how to make a multichannel ogg file?

i just know that i can transform a multichannel wav to multichannel ogg.

is there a direct way to do it?

and so is to aac.

I used HeadAC3he and or ogg machine to rip to a multichannel ogg......with the aotuvb3 encoder.........

vorbis isnt really useable for multichannel as the current encoders dont support channel coupling, so you might end up having good results only on pretty high bitrates

i hope someone will soon implement channel coupling in an encoder, its really missing for vorbis

The Ogg Vorbis spec supports multichannel coupling alright. oggenc even supports stereo coupling right now. You can't get uncoupled stereo with modern encoders.

It's multichannel coupling that's unsupported right now, and I agree it's sorely needed.

I was planning on ripping my dvdcollection to harddrive/dvds in XviD/Oggvorbis mkv-format... but know I read this! no multichannel coupling??

Do those people behind vorbis don't realize there is a big competition going on?
AAC is now the best solution for dvd>xvid... or just keep the AC3...

I wanted to do the same thing. Currently I rip my DVD's using xvid & vbr he-aac in a matrosak container. You end up with a 6ch file thats roughly 128kbps and it sounds great for the size. Allows better quality video too.
EDIT: forgot to mention, maybe it's just me, but he-aac audio seems to use a considerably larger amount of CPU than mp3 or AC3 audio rips. On a 350mhz box I can play anything but movies with he-aac audio. If CPU useage matters to you.
