how to encode multichannel audio from avisynth

since avisynth can handle multichannel audio i wonder how i can encode from an avs file for example to aac thx in advance for any help

I'm not even sure you can. If you want to encode the audio use something like BeSweet for mp3 or OAGMachine for OGG and AAC encoding.

well, if avisynth can handle multichannel, then there must be a way to get it out of there...

I'm also wondering about this for a long time. I guess you can use avs2wav to convert it to a wav first.

right, if that supports 6chwave then it could be used to make an intermediat wave file

Doesn't it support multichannel wav or haven't you tried it yet?

haven't tried yet if not i still can out put the 6 channels seperately (i assume it'll support mono)

I export to an intermediate WAV-file from Vdub, before compression. I seem to remember Besweet also supporting AVI input, so direct input into Besweet should be possible - if not directly then through a ffvfw fake AVI file.

i'll try vdub then first next time (i forgot the obviouse again) on some rough tests direct input into besweet didn't work i remembered that fake avi thing, but not how to do it, so thx for the clue ("ffvfw")

if you want 6 channels, I would extract them to 6 wave's one at a time, then join them using heada3c or something... not sure if this is what you were asking or not.
