Methods for encoding and synthesizing a set of audio signals, encoders for encoding a set of audio signals and to encode audio channels.The decoder to synthesize a set of audio signals, carrier of data, and coded signal.A method that uses the sources in a system of audio coding of multiple channels for encoding a set of audio signals in which related components are present.The method includes the step of determining, from the relation between said audio signals, a composition of these sources.The composition is such that the sources in said composition are substantially not correlated.So that said composition of sources synthesizes said components in a way of relation preserved.The method can also include the step of encoding the sources, determining for each source a set of parameters for synthesizing said source.And a set of processing parameters to generate said composition of sources.
