Hi. I have an idea for an iPhone application for which I need to generate
sound.
I studied different documents but it is not clear to me how to do this.
The problem is that I need to generate real time audio myself. I will
calculate each next sample using a sound algorithme.
I think the preferred method is using Audio Units. But it is not clear to me
if this can be done on the iPhone.
There are Audio Units in iPhone but can I define my own?
Some documents talk about using openAL, But this seems a lot of overhead for
my needs.
My sound generation algoritme is flexible. I can generate more detailed
sounds when processing power is available.
I would like to use that to automatically adapt to the available processing
power.
For instance making it such that I never use more then 50% of the processor
time so that enough processing power will be
available for other things (like the GUI). Is that possible? Is there for
instance a main clock count that I can use to time my
algorithme?
Any advise is very welcome. Thanks.
