what is the most common FFT

Hi,

I want to examine sounds in the fourier space. I dcided to use Core Audio for audio handling, but didn't find any fourier transformation. I figured, that there is an DSP Library from Apple, but that is from 2001 and there are a lot of fast 3rd party altifec implementations.

I just started with Mac and of course I'm also new to programming under Mac, but so far I figured, that Apple provides the community with very nicly designed framewors and I just wondered we the FFT is.

Have I overloocked something? What is the best way to examine a stream in the fourier space, change it an transform it back fro play back?

Thanks!
  Christoph
