1. A method for decoding a bit stream comprising M input audio channels, wherein M is at least 3, the method comprising:
extracting side information from the bit stream;
stereo decoding a first pair of audio channels based on the side information, from the M input audio channels; so as to obtain two stereo decoded audio channels, wherein the two stereo decoded audio channels combined with M−2 of the input audio channels not included in the first pair of audio channels form a first set of M audio channels; and
stereo decoding a second pair of audio channels so as to obtain two additional stereo decoded audio channels, wherein the two additional stereo decoded audio channels, together with the M−2 of the audio channels, form a second set of M audio channels.
