Abstract (en)
[origin: WO2017153697A1] The invention pertains to a method of parametric coding of a multichannel digital audio signal comprising a step (312) of coding a signal (M) arising from a channels reduction processing (307) applied to the multichannel signal and of coding spatialization information of the multichannel signal. The method is such that it comprises the following steps: - extraction (314, 320) of a plurality of items of spatialization information of the multichannel signal; - obtaining (315, 317) of at least one representation model of the extracted spatialization information; - determination (315, 411) of at least one angle parameter of a model obtained; - coding (316, 318) of the at least one determined angle parameter so as to code the spatialization information extracted during the coding of spatialization information. The invention also pertains to a method for decoding such a coded signal and corresponding coding and decoding devices.
