This is an opportunity to bring up a question I've been thinking about
for a bit now... Have you thought about adding a way to indicate the
speaker arrangement for multi-channel devices?
My preference would be nice to throw this into the
AudioStreamBasicDescription structure so *any* multi-channel buffer can
carry around its assumptions about which speakers are represented by
which channels. There's that mReserved field in ASBD just begging to be
used :)

We will have something that can do all of this in the Panther release
of the SDK (though I'm not exactly sure what you mean by "RAW")
The code we're working on (hopefully this all gets done!), will also
show you how to use the matrix mixer to down mix from different
channel layouts, as well as both encoding and decoding ADTS files that
have quite a few different surround formats for AAC (various flavours
from mono to 8 channels).
So, all in all, could be interesting I think

For audio quality evaluations I need to play back 5 channel PCM (AIF,
WAVE, or RAW) files. Is there a simple player for MacOS X that
supports such multi-channel playback (shareware/freeware/relatively
cheap and simple software)?
If not I guess I have to write my own (hopefully not).
Does anyone know more? Thanks,
Chris
