iOS Audio Service : Read & write audio files

guys.

I'm working on some audio services on iOS.

I trying to search any examples or tutorials about

how audio service or stream can read a existing audio file than

process something like filter, than write another file.

Is there any body who can help me?

Answer

Dirac3LE (by Stephan M. Bernsee) is a great library for this job.

There are examples and manual included in the download.

It is particulary inteded for time and pitch manipulation but in your case you'll be interested in its EAFRead and EAFWrite classes.
