摘要： A method using synthetic noise sources in a multi-channel audio coding system for encoding a set of audio signals wherein correlated noise components are present. The method comprises 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 mutually uncorrelated, so that said composition of noise sources synthesizes said noise components in a relation-preserved way. The method may further comprise the step of encoding the noise sources, by determining for each noise source a set of noise parameters for synthesizing said source and a set of transformation parameters for generating said composition of noise sources.
