You probably want to visualize it in an other way. *The first bin in the FFT is DC (0 Hz), the second bin is Fs / N, where Fs is the sample rate and N is the size of the FFT. The next bin is 2 * Fs / N. To express this in general terms, the nth bin is n * Fs / N. So if your sample rate, Fs is say 44.1 kHz and your FFT size, N is 1024, then the ...
