ABSTRACT:
A method and arrangement for automatically limiting distortion in audio devices utilizes a distortion detector for determining a harmonic distortion factor and the output of the distortion detector is fed back to a gain regulation input of the audio device. The distortion detector determines the harmonic distortion factor of the output signal of the audio device in a frequency-dependent manner and, when the harmonic distortion factor exceeds a frequency-dependent, adjustable threshold value, the detector generates a control signal that reduces the gain of the audio device.
