摘要：The present document relates to audio encoding/decoding. In particular, thepresent document relates to a method and system for improving the quality of encodedmulti-channel audio signals. An audio encoder configured to encode a multi-channelaudio signal according to a total available data-rate is described. The multi-channel audiosignal is representable as a basic group (121) of channels for rendering the multi-channelaudio signal in accordance to a basic channel configuration, and as an extension group(122) of channels, which—in combination with the basic group (122)—is for rendering themulti-channel audio signal in accordance to an extended channel configuration. The basicchannel configuration and the extended channel configuration are different from oneanother.
