Describes the multi channel encoder (10), for processing in the N input signal transmitted in the channel (300310320330340) to generate the corresponding output signal in the M output channel is transmitted (480490) and the supplementary data parameters (370430450); M and N is an integer, the N>M. The encoder (10) comprises a mixer for mixing the input signal (30310320330340) to generate the corresponding output signal (480490), the encoder also includes an analyzer for processing the input signal (300310320330340) to generate data (370430450), the data described between the input signals of N channels are poor, to allow during decoding output signal from the M channel to generate one or more input signals of N channels. Such an encoder (10) is capable of providing efficient data encoding and capable of backward compatibility with a relatively simple decoder with less than N decoded output channels. The invention also relates to a decoder compatible with such a multi-channel.
