AB  - The following coding scenario is addressed: A number of audio source signals need to be transmitted or stored for the purpose of mixing stereo, multi-channel surround, wavefield synthesis, or binaural signals after decoding the source signals. The proposed technique offers significant coding gain when jointly coding the source signals, compared to separately coding them, even when no redundancy is present between the source signals. This is possible by considering statistical properties of the source signals, properties of mixing techniques, and spatial perception. The sum of the source signals is transmitted plus the statistical properties which determine the spatial cues at the mixer output. Subjective evalution indicates that the proposed scheme achieves high audio quality.
