An audio system includes a circuit (12) for processing an audio signal, the circuit (12) having an input (20) for receiving the audio signal and an output (26) for supplying an output signal. The circuit (12) further includes a harmonics generator (22) coupled to the input (20) for generating harmonics of the audio signal and an adding circuit (24) coupled to the input (20) as well as to the harmonics generator (22) for supplying a sum of the audio signal and the generated harmonics to the output (26). The harmonics generator (22) includes an integrator (34) for integrating the audio signal, and, coupled thereto, a resetting circuit (36) for resetting the integrator (34) at resetting times.
