but they all have to be of the same ASDB format, right? I saw
somewhere else on this list that the mixer is pretty much just doing
channel mapping, which implied that it wasn't performing format
conversion.

yep - the matrix mixer can be configured to any number of buses with

Hi All,
I'm wondering if an AUMatrixMixer has the capability to accept
different inputs on its input busses. E.g. can I put 5 channels of
44.1k into Bus 0 and 2 (stereo) channels of 8k into Bus 1 and
expect things to work - or am I asking for trouble? Another way
of asking this I suppose, is; will it perform the format and rate
conversion tasks for me - or do I have to make sure all the input
*and* output busses are set to the same format/channel and sample
rate?
Reason:
I have a situation where I'm going to be feeding audio from QT
movie files into coreaudio units. I'm extracting audio via the
MoveAudioExtraction API, which for any given movie creates a
summary mix of all of the audio tracks contained in the movie, I
then need to push these into a ducking component (that I'm going to
write).
Thanks
