Abstract
Artifacts are reduced during a frequency compression of an audio signal in a hearing device, in particular in a hearing aid. An amplitude information of a source channel is obtained, for example a spectral envelope, from several frequency channels of the audio signal. An amplitude corresponding to the amplitude information is then applied on a signal in a target channel of the several frequency channels, on which the source channel is represented during frequency compression.
