I have a question about rendering multiple audio inputs.
if I have a mixer node with five input busses to render five audio
inputs, I suppose I can use AudioUnitSetProperty to manipulate the
panning and volume of each audio input,
AudioUnitSetParameter actually
but is there any property to alter the current playing time of each
audio input( each bus)? For example: by setting the respected
property the current time jumps from 1:25 back to 0:00
I think this is beyond the audio unit - the audio unit is just
rendering samples, it has no notion of a time line, or of where those
samples come from - that is above the audio unit and up to your
program that is feeding the data into the audio unit to manage that.
another example, the five audio inputs are now playing concurrently,
and there are five buttons on the window, when the user triggers one
of them, the respective audio stream will rewind to the very
beginning, while the other audio inputs are not influenced.
same - its all about how you handle which audio is fed when to which bus

any suggestion would be appreciated!!
