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.
