How do I obtain the frequencies of each value in an FFT?
...0 / 1024 = 22006.9 Hz
Note that for a real input signal (imaginary parts all zero) the second half of the FFT (bins from N / 2 + 1 to N - 1) contain no useful additional information (they have complex conjugate symmetry with the first N / 2 - 1 bins). The last useful bin (for practical aplications...
