FFT routines?
Posted:

Hello all!
I'm trying to produce some code to do a FFT on realtime audio data, with me final goal being soemthing along the lines of speech recognition. I've found several source code examples, in x86 asm, c++, fortran and pascal, but they are all completely uncommented (eg: this does the fourier thing, ignore it, it's difficult) I'd like to write my own routines, but I have no clue as to the basis behind the process. I'm okay with most aspects of calculus, so a brief outline would be much appreciated. :)
Thanks in advance, james
