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.

Hi all,
is anyone here using fftw (www.fftw.org) with cocoa?
