The human voice can reach approximately 4 kHz and we need to bound our
sampling rate from below by at least double this frequency ( see the discussion of
the Nyquist sampling rate , below ) . Thus we arrive at the useful range about 8 to
Fundamental frequency + 0 . 5 x 2 x fundamental + 0 . 33 x 3 x fundamental + 0 .
