Re: fftw... ?

FFTW has AltiVec extensions as well, so I don't know that vDSP has any real advantage there... I've been using FFTW in a Cocoa audio analysis app and it works quite well, couldn't be easier to implement.

I don't know much about FFTW, but I do know that Apple provides an incredibly fast FFT library called "vDSP." It's fully AltiVec-accelerated so it is likely that it blows FFTW out of the water--even if their algorithms are the best, AltiVec has an inherent four-to-one advantage.
Check out the Accelerate framework for details.
