An AU's input can be one of two types:
(1) An input callback - so it gets input by calling a render callback
function
(2) A connection to another AU - so it gets its input calling
AudioUnitRender on the connected AU
So, given this topology:
AUHAL Input -> processing node -> AUHAL Output
what is it that you are trying to achieve with your render callback -
and where is it attached too?

Hi,
I have created an AUGraph with two node , first is the ioNode which is
my io device and second which is my audioNode for processing.
I would like to connect the input device into the AudioUnit , do some
processing and send it into the device output.
Accourding to the API( I Hope) , all I need to do is to connect the
ioNode bus 1 into audioNode bus 0 and audioNode bus 0 into ioNode
bus 0.
( I use the same Audio device as input and output).
I'm tring to set the AURenderCallback(... AudioBufferList
*ioData...) of
the audioNode and my question is:
Does the ioData parameter is input/output? meaning Does it contain the
sound buffer which I can process apon?
Or does ioData is empty and I should fill it with sound?
Thanks,
Amir.
