Hi all,
my problem is the following:
I want to load a .aif file apply a very simple delay AU and play it back on iPhone.
What I have done so far?
1) I have create a AUGraph with mixer unit (I would like to add another track in the future) and Output Unit.
2) I have a piece of code that put the aif file in a queue (there is not input unit in iPhone)
Questions:
a) how I can connect at least the queue loaded of buffer from the .aif to the input of the graph?
b) how can for example (if possible) using the Apple AU for delay and add it to my chain? If not possible using the Apple one i have written one so the question it self does not change: how can I connect my code to the other pieces?
c) I'm reading this list since few weeks now and heard several time of RenderCallBack. Now even reading the AudioUnit guide I don't think I have a real understanding about what is going on so can someone include an explanation please?
Thank you very much!
I really appreciate your help.
Gabriele
