Method for compensation audio signal components in a vehicle communication system and system therefor

摘要

Method for compensating audio signal components in a vehicle communication system, comprising the steps of:
- detecting, by a microphone (11), a sound signal in a vehicle, the sound signal comprising audio signal components resulting from reproducing an audio signal of an audio source in the vehicle, the sound signal further comprising speech signal components corresponding to a speech signal from a passenger of the vehicle,
- filtering the sound signal in order to whiten the sound signal,
- compensating the audio signal components in the whitened sound signal,
- removing the whitening of the compensated sound signal,
wherein the filtering of the audio signal is performed using at least two filters in an alternating way, each filter using time-dependent filter coefficients.
