Abstract

and an outputter, wherein for an integer n, an nth stereo decoder of the N stereo decoders decodes an nth pair of audio channels, wherein the nth pair of audio channels are part of a (n-1)th set of the P input audio channels, to obtain an nth pair of stereo decoded audio channels, wherein the stereo decoding include forming, for at least one frequency band and at least one time frame, a weighted or non-weighted sum and a weighted or non-weighted difference of the (n-1)th pair of audio channels subjected to the respective stereo decoding, and wherein the outputter outputs the Nth set of the P input audio channels.
