Abstract:
An audio decoder for providing at least four audio channel signals on the basis of an encoded representation is configured to provide a first residual signal and a second residual signal on the basis of a jointly encoded representation of the first residual signal and of the second residual signal using a multi-channel decoding. The audio decoder is configured to provide a first audio channel signal and a second audio channel signal on the basis of a first downmix signal and the first residual signal using a residual-signal-assisted multi-channel decoding. The audio decoder is configured to provide a third audio channel signal and a fourth audio channel signal on the basis of a second downmix signal and the second residual signal using a residual-signal-assisted multi-channel decoding. An audio encoder is based on corresponding considerations.

Claim (Index 11):
The audio-decoder according to  claim 10 , wherein the parameter-based residual signal-assisted multi-channel decoding is configured to evaluate one or more parameters describing a desired correlation between two channels and/or level differences between two channels in order to provide the two or more audio channel signals on the basis of a respective one of the downmix signals and a corresponding one of the residual signals.
