All, Lets say I have a 16 channel file, but 10 of those channels are empty (all values are 0). For a) the vorbis codec and also b) the FLAC codec ... would the size of the file be close to (or practically the same as) the size of a 6 channel file? Etienne

Though I don't know how big the differences in CPU cycles is (if the Vorbis codec is more efficient on digital silence than it is on average content). FLAC doesn't support 16 channels.
I expect this has probably already been discussed but .... are there any plans for a >8 channel Flac implementation?...
