Abstract
A method performs frequency distortion of an audio signal. The audio signal is divided at at least one division frequency into a low-frequency band and a high-frequency band. A frequency-distorted signal is generated through respectively different distortions of frequencies for the high-frequency band and for the low-frequency band. The division frequency is selected such that it is located between two neighboring tones of a given tonal system.
