ABSTRACT:
A system for enhancing sound quality comprising a filter that square roots the instantaneous amplitude of frequencies in an input signal for generating artificial harmonics corresponding to said frequencies. The system can comprise an automatic level control that momentarily boosts the amplitude of a higher frequency portion of the input signal to emphasize attack transients occurring within the input signal.
