We generally overide AUBase and just implement the Render method -
then instead of working around all this stuff, you just implement
what you need. I think its clearer and easier (but many have ignored
me in the past!)

Hi Paul!
Unfortunately there is more work to do. You also have to modify the
function that creates the kernels (MaintainKernels()) so that you
have your stereo kernel set up correctly (it usually creates one
kernel per I/O which is not what you want). If you want to support
stereo processing only you can just create one instance of your
Stereokernel. If you want to support both mono and stereo
processing you will have to do some more work there.
Then, you have to modify ProcessBufferLists() which is the function
that finally calls the Process() functions of the kernels.
I can't really remember the details, but just look around the
methods I named and try to understand what they do. Then it
shouldn't be a problem to modify everything accordingly. Hey, even
I got it to work! ;)
Greets,

ok thanks, well couldnt i create two classes like myAUEffectBase
and myAUKernelBase, and have them inherit AUEffectBase and
AUKernalBase respectively and just overide ProcessBufferList() to
use myAUKernelBase, which will have an additional function called
ProcessStereo() or would i need to overide other functions as
well? also, where do i set the audio unit to only recieve mono or
stereo, and set the output to only stereo?
thanks,
paul

short version - there is a long version but it would require
refactoring much of the code of AUEffectBase and its kernel
objects that is probably too lengthy to go into here I think).�

I would like to set up my audio unit to process stereo, is there
someway i can set it up so that it will call a funtion like this
in my class to do the processing:
void ��� ��� ��� ��� Process(���
const Float32 * ��� inSourceLeft, // left input
��� �� �� �� �� �� �� �� ��
�� �� �� �� const Float32 * ���
inSourceRight, //right input

��� ��� ��� ��� inFramesToProcess,
��� ��� ��� ��� ��� ���
��� ��� ��� ��� ��� bool &���
��� ��� ��� ioSilence)
i am inherenting AUKernelBase, and AUEffectsBase, can i just
override ProcessBufferList() in my class? and if so how would i
write the code to call this function that is located in my kernel
(e.g. class myAudioUnitKernel : public AUKernelBase)?
