How do I change playback speed using coreaudio api?

Hello,

I have written a small cocoa/c++ app that reads an AIFF file into a buffer
and then plays it. I would like to add a simple slider control to the UI to
allow me to change the playback speed in real time without changing the
pitch. Do I need to use FFT code or can I simply change the data in the
buffer that I feed to the callback routines in the AudioConverter and
OutputDevice objects?

Thanks,

Rick Shane
