Abstract
A system (1) is described which is suited for suppressing audio distortion. The system comprises echo cancelling means g1, g2 coupled between an audio output (4) and a distorted desired audio sensing microphone array (3), and a filter arrangement (7) coupled to the echo cancelling means g1, g2 and/or the microphone array (3). The filter arrangements' coefficients represent reverberation distortion in the desired audio sensed by the microphone array (3).

A system (1) for suppressing audio distortion, comprising:
- echo cancelling means (g1, g2) coupled between an audio output (4) and a distorted desired audio sensing microphone array (3), and
- a filter arrangement (7, 7A) coupled to the echo cancelling means (g1, g2) and/or the microphone array (3), the filter arrangement including filter (7A) coefficients (w;
- w1, w2) representing reverberation distortion in the desired audio sensed by the microphone array (3).
