OK, I was just looking at the Audio Unit parameter units (like kAudioUnitParameterUnit_Generic), and I noticed that they all say "Available in iOS 2.0 and later." So, why create an API for Audio Units, and then not allow people to create and use their own in their own apps?

So, if I wanted to create closed source DSP code libraries for others to use in their products, what format would be optimal for delivery?

Thanks,

Sean Costello

That's correct. I think everyone who reads that documentation for the first time is left with an uncertainty about how to use custom audio units in an iOS project, when in fact you are limited to the multichannel mixer, remoteIO and a few others...

Sean,

I think that is the point.  As far as I understand it (I'm sure someone will correct me if I am wrong), the current architecture only allows the use of the six defined apple AUs.  If you want to do some audio processing beyond this functionality then it must be done in the render callbacks.

I read that document. It only discusses linking to Apple Audio Units. I'm interested in creating closed-source Audio Units that developers can integrate into applications. I'm not sure if this is a good idea or not - just looking into the technical feasibility of the idea.
