Claim:
1. An audio signal processor comprising: a receiver for receiving a plurality of encoded multi-channel audio signals; a multi-channel decoder for decoding a first encoded multi-channel signal of the plurality of encoded multi-channel audio signals to generate a first decoded multi-channel signal; a generator for extracting an encoded further audio signal by selecting encoded audio data from at least a second encoded multi-channel audio signal of the plurality of encoded multi-channel audio signals such that a number of channels of the encoded further audio signal comprising encoded audio data from the second encoded multi-channel audio signal is less than a number of channels in the second encoded multi-channel signal; a further decoder for generating a decoded further audio signal by decoding the encoded further audio signal; and a combiner for combining at least the first decoded multi-channel signal and the decoded further audio signal to generate a multi-channel output signal.
