Abstract
A system () is described which is suited for suppressing audio distortion. The system comprises echo cancelling means (g, g) coupled between an audio output () and a distorted desired audio sensing microphone array (), and a filter arrangement () coupled to the echo cancelling means (g, g) and/or the microphone array (). The filter arrangement () includes filter coefficients representing at least a part of the audio distortion, such as reverberation. The system also comprises an at least partly mirrored circuit arrangement (g',′) for copying thereby simulated audio distortion representative filter coefficient values into the filter coefficients of said filter arrangement (). Such copied values can be then used for suppressing reverberation in a distorted desired signal by the filter arrangement ().
