    A principle used by engineers when designing equipment for the digitization of analog signals. Due to the complex nature of sampling audio, the theory states that for any given sample rate, the maximum bandwidth of the analog source must fall below one half the sampling frequency. If this formula is not followed, errors in the form of aliasing will be introduced into the data file. To prevent this happening, analog to digital converter usually have steep filters to remove any material above the Nyquist frequency.
