It's implemented as a MatrixMixer AudioUnit, which means I'll have to  
pass this question on to the CoreAudio mailing list and see if they  
answer it, as I don't see it showing up in the docs anywhere.

I hope the question I'm about to ask isn't as dumb as I think it is,  
but...

I'm not sure I understand why it would matter whether you apply the  
gain to the inputs or the outputs.

Keep in mind that all internal CoreAudio processing is done at 32 bit  
floating point resolution, so I don't think there is a resolution  
issue involved...or is there?

Apologies if I'm being stupid.
