Why not make up a signal from six totally
different mono wavefiles and see where they land after decoding?

So channel ordering (normally) is W, Y, Z, X, L, R.
It is possible to change the channel layout, which might be a
problematic feature...
For example, a channel layout of 4, 5, 0, 1, 2, 3 indicates that the
layout of the stored audio is /L/, /R/, /W/, /Y/, /Z/, /X/.

and 339 (vorbis).
So to get the aac stream (with an audio
container, using the "-x" option):

stream has 6 channels, so 2 of them are silent. No
idea about the channel ordering. If prefered, the opus and vorbis

a "stream and decode" pipeline

FR'6öÖUö6öÖÖæEöÀine_decoder" is a script or software that can
decode the stream from STDIN (so a proper Unix OS is required).
