Abstract:
1. Multi-channel encoder for encoding an original multi-channel signal having at least two channels, comprising: a parameter provider for providing one or more parameters, the one or more parameters being formed such that a reconstructed multi-channel signal can be formed using one or more downmix channels derived from the multi-channel signal and the one or more parameters; a residual encoder for generating an encoded residual signal based on the original multi-channel signal, the one or more downmix channels or the one or more parameters so that the reconstructed multi-channel signal when formed using the residual signal is more similar to the original multi-channel signal than when formed without using the residual signal, the residual encoder including: a data stream former for forming a data stream having the encoded residual signal and the one or more parameters.
