Abstract:
The following coding scenario is addressed: A number of audio source signals need to be transmitted or stored for the purpose of mixing wave field synthesis, multi-channel surround, or stereo 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, the properties of mixing techniques, and spatial hearing. The sum of the source signals is transmitted plus the statistical properties of the source signals which mostly determine the perceptually important spatial cues of the final mixed audio channels. Source signals are recovered at the receiver such that their statistical properties approximate the corresponding properties of the original source signals. Subjective evaluations indicate that high audio quality is achieved by the proposed scheme.

Claim (Index 2):
A method for synthesizing a plurality of audio channels, comprising:\n retrieving from an audio stream at least one sum signal representing a sum of source signals, retrieving from the audio stream statistical information about one or more source signals, receiving from the audio stream, or determining locally, parameters describing an output audio format and source mixing parameters, computing output mixer parameters from the received statistical information, the parameters describing an output audio format, and the source mixing parameters, and synthesizing the plurality of audio channels from the at least one sum signal based on the computed output mixer parameters, wherein the synthesizing comprises a decorrelation processing.
