-The Nyquist frequency, equal to 1/2 of a given sample rate, is the
-maximum frequency component that can be represented by a discretized
-signal at that sample rate. For example, the human hearing range is
-typically assumed to extend up to approximately 20 kHz, and so a digital
-audio signal must have a sample rate of at least 40 kHz to represent that
-range. In practice, sample rates of 44.1 kHz and 48 kHz are commonly
-used, with Nyquist frequencies of 22.05 kHz and 24 kHz respectively.
