Abstract (en)
[origin: EP2437258A2] The method involves providing an audio signal in a frequency channel (14'). A dominant instantaneous frequency (14'') is determined in the frequency channel. The channel including the instantaneous frequency is displaced or reproduced in another channel. A permanent frequency position (fd) for the instantaneous frequency is determined by a preset compression characteristic line in the latter channel based on a frequency position (fs) of the instantaneous frequency. The instantaneous frequency is displaced or reproduced from an intermediate frequency position (fz) to the permanent position. An independent claim is also included for a device for compressing frequency of an audio signal.
