Yes, I'll try, but I havn't learnt much about them yet. It would seem
through feedback from the list, that fourier transforms are not the best way
to do filtering on DSPs, but I'll try to explain anyway. Fourier transforms
allow you to extract the amplitude and other usefull stuff of any given
frequency when provided with a spectrum of audio (Or more usually, RF) data.
You can use this information to make any type of filter you want.

This may well be wrong, so mail the list if it is!
