Method using synthetic ruu00ecdo sources in a system of audio coding of multi channels for encoding a set of audio signals, an encoder to encode audio channels encoded.Decoder for receiving encoded audio channels and processed, and the bearer of the data ".A method using synthetic noise sources in a system of audio coding of multi channels for encoding a set of audio signals.In the components of correlated noise are present.The method includes the step of determining, from the relation between said audio signals, a composition of noise sources.The composition being such that the noise sources in said composition are correlated each other.So that said composition of noise sources summarize these components of noise in a way preserved in relation to the relationship.The method can also include the step of coding noise sources, by determining for each noise source.A set of noise parameters for synthesizing said source and a set of processing parameters to generate said composition of noise sources.
