Claim 26:
27. Non-transitory digital storage medium having a computer program stored thereon to perform the audio decoding method of decoding an encoded multi-channel audio signal comprising encoded channels and at least first and second multichannel parameters, comprising:
decoding the encoded channels to acquire decoded channels; and
performing a multichannel processing using a second pair of the decoded channels identified by the second multichannel parameters and using the second multichannel parameters to acquire processed channels, and performing a further multichannel processing using a first pair of channels identified by the first multichannel parameters and using the first multichannel parameters, wherein the first pair of channels comprises at least one processed channel,
wherein the encoded multi-channel signal comprises, for a first frame, the first and the second multichannel parameters and, for a second frame, following the first frame, a keep indicator, and
wherein the multichannel processing and the further multichannel processing in the second frame is performed on the same second pair and the same first pair of channels as used in the first frame,
when said computer program is run by a computer.
