Base Claim:
1. A process for communicating multi-channel audio data, the process comprising: encoding with a first audio matrix encoder, a first plurality of surround audio channels to create a first pair of encoded audio channels, wherein the first pair of encoded audio channels have the first plurality of surround audio channels encoded therein; encoding with a second audio matrix encoder, the first pair of encoded audio channels with a plurality of different language channels to create a second pair of encoded audio channels, wherein the second pair of encoded audio channels have the first plurality of surround audio channels and the plurality of different language channels encoded therein; transmitting the second pair of encoded audio signals from a sender to a recipient; decoding with a first matrix decoder the second pair of encoded audio signals to generate the first pair of encoded audio signals and the plurality of different language channels; decoding with a second matrix decoder the first pair of encoded audio signals to generate the first plurality of surround audio channels; selecting at least one of the different language channels; and mixing the at least one selected language channel with the decoded surround audio channels to obtain a second plurality of surround audio channels, the second plurality of surround audio channels including the selected language channel.
