Hi Meisi,
A late response, but check out Numerical Recipes at this site:
Chapter 12 is about fourier transforms, and chapter 13 about several uses of it. Check 13.5 for digital filtering without the need of a FFT. And, of course, the rest of the chapters contain a lot of cool information about all sorts of algorithms. Hope this helps!

: Does anyone know, where i could get a subscription "how to program a frequency analyzer"?
: (like you can see it on some equalizers or winamp)
: I searched the www for fft, fourier, etc but it seems, nobody offers any information about this thema.

I think i will get some infos about fft there.
but i am not good in math/english.
so i will take a few weeks until i understand the whole thing.
