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 8):
The audio decoder according to  claim 1 , wherein the audio decoder is configured to provide the first residual signal and the second residual signal on the basis of the jointly encoded representation of the first residual signal and of the second residual signal using a multi-channel decoding which is operative in a MDCT domain.
