Abstract
A multi-channel audio encoder () encodes an N-channel audio signal. A first unit () generates a first encoded M-channel signal, e.g. a spatial stereo down-mix, for the N-channel signal (N>M). Down-mixers () generate first enhancement data for the signal relative to the N-channel audio signal. A second M-channel signal, such as an artistic stereo mix, is generated for the N-channel signal. A processor () then generates second enhancement data for the second M-channel signal relative to the first M-channel signal. A second unit () generates an output signal comprising the second M-channel signal, the first enhancement data and the second enhancement data. The generator () can dynamically select between generating the second enhancement data as absolute enhancement data or as relative enhancement data relative to the second encoded M-channel signal. A decoder () can perform the inverse operation and can apply the second enhancement data as absolute or relative enhancement depending on an indication in the received bit-stream.
