Abstract
A multi-channel audio encoder () for encoding a multi-channel audio signal (), e.g. a 5.1 channel audio signal, into a spatial down-mix (), e.g. a stereo signal, and associated parameters (). The encoder () comprises first and second units (). The first unit () encodes the multi-channel audio signal () into the spatial down-mix () and parameters (). These parameters () enable a multi-channel decoder () to reconstruct the multi-channel audio signal () from the spatial down-mix (). The second unit () generates, from the spatial down-mix (), parameters () that enable the decoder to reconstruct the spatial down-mix () from an alternative down-mix (), e.g. a so-called artistic down-mix that has been manually mixed in a sound studio. In this way, the decoder () can efficiently deal with a situation in which an alternative down-mix () is received instead of the regular spatial, down-mix (). In the decoder (), first the spatial down-mix () is reconstructed from the alternative down-mix () and the parameters (). Next, the spatial down-mix () is decoded into the multi-channel audio signal ().
