Hi, say I have an array of data like this:

UCHAR Data[100];

Values range from 0-255 or -128 to 128 after translation. I need to know how to calculate FFT tables (fast fourier transform?) so I can get the frequencies I need for my voice recognition system. If possible, about 50 entries ranging from 0 to 100 ?

Thanks!

I have some src code dealing with FFT.
If you want them, I can email them to you.
