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?
Add the Accelerate.framework to your project, and use the vDSP
functions (examine the headers for current info). You'll find a wealth
of power at your disposal.
