The CASpectralProcessor class in the CA SDK might do what you need: it
transforms an audio stream into the frequency domain, lets your
subclass adjust the frequencies, and then transforms it back into
samples.
Even if you can't use it as-is, it's a good example of how to use
Accelerate.framework to do FFTs.
