摘要: A process and apparatus (a) for reducing the perceived noise without perceptible loss of fidelity upon aural reproduction, an audio input signal in electrical form by means electronic circuit wherein upper limit bandwidth is automatically continuously adjusted accordance with relationship (i) peak amplitude rate change respect to time (ii) instantaneous within a selected frequency band signal, (b) system detecting discriminating between transients retaining output signal.
