I want to use Open AL for the iPhone but it is to low level

Question

I want to change the pitch of my audio and I know that AV Foundation is not the place to look for that, but I don't want to learn Open AL because it is to low level, does anyone know what I would use as an alternative?

Answer 1

Take a look at Dirac 2 for iPhone:

If you want to implement this yourself, you could also consider using Core Audio and the RemoteIO audio unit.
Core Audio is also a low level API, but if you want to do DSP, you will have to use this kind of APIs sooner or later.

To get started with the RemoteIO unit:

Answer 2

take a look at this link. Lately, I used csound API for creating MIDI sounds. But OpenAL is cross-platform audio manipulation library that is supported on the iPhone. Hope this answer helps you. Take a look at this FAQ.
