Abstract (en)
[origin: WO2014117867A1] The invention relates to a method for processing a multichannel sound in a multichannel sound system, wherein the input signals L and R are decoded, preferably as stereo signals. The aim of the invention is to develop the method such that a further improvement of the spatial reproduction of the input signals L and R is achieved on the basis of an extraction of direction components. According to the invention, this is achieved in that the signals R and L are decoded at least into two signals of the form nL-mR, in which n, m = 1, 2, 3, 4.
