Abstract (en)
[origin: WO2005083678A1] The invention relates to a device for processing a multi-channel signal comprising a unit (12) for determining a similarity between the first of two channels and the second of two channels. The device is also equipped with a unit (16) for carrying out a predictive filtering of the spectral coefficients, said unit being configured to carry out a predictive filtering by means of a single predictive filter (16a) for both channels, if the first and second channels are very similar and to carry out a predictive filtering by means of two separate predictive filters (16b), if the first and the second channels are dissimilar. This prevents the introduction of stereo artefacts and a degradation of the coding gain in stereo coding techniques.
