CIRCUIT, AUDIO SYSTEM AND METHOD FOR PROCESSING SIGNALS, AND A HARMONICS GENERATOR

摘要

A circuit, audio system and method are presented for processing an audio signal, in which a frequency band is selected, harmonics are generated from the selected signal by a harmonics generator, wherein the harmonics are scaled by a level detected in at least a part of the spectrum of the audio signal related to the selected frequency band. Furthermore, a harmonic generator is presented for generating arbitrary harmonics of an input signal.
