Method for processing a stereo signal comprising: Encoding á N-channel audio signal in a stereo signal (Lo, Ro) and spatial parameters (wl, wr), processing the stereo signal using the spatial parameters for generating a processed stereo signal (low, Row). The matrix of the processed stereo signal can be discribed as the matrix of the stereo signal, multiplied by a filter matrix (H) which element are filter functions (H 1 , H 2 , H 3 , H 4 ) operated with spatial parameters (wl, wr) and a constant (a). The filter functions are time invariant and selected so that the matrix is invertible. |
