Thank you very much - very helpful. Also, thanks to another post I've
finally discovered the documentation...
/Developer/Examples/CoreAudio/Documentation/index.html
Have a look at the code in AUEffectBase::Initialise - the host is
responsible for setting formats (num channels) for an AU, and the
AU in its Initialise call is responsible to ensure that these
formats are supported.
You should also bare in mind that AUEffectBase is primarily
designed to work with N-N channel processing. If you are going to
process say Mono input to Stereo Output, then you can't use the
kernels, in place processing and bypass in AUEffectBase do not work
without some modification - our recommendation is to start from
AUBase instead (that is what we do ourselves). My suggestion would
be to ignore the mono-stereo case for the moment, and get
everything sorted out by using AUEffectBase as a starting point.
