ABSTRACT:
Systems and processes for transmission of multi-channel audio from a sender to one or more recipients. Multi-channel audio is encoded with a plurality of different dialog channels. The encoded multi-channel audio and dialog channels can be compressed to facilitate transmission with limited bandwidth. A recipient can select a desired dialog channel from the plurality of dialog channels transmitted. A receiver side decoder can reconstruct a multi-channel audio with the selected dialog for playback. The plurality of dialog options can include different languages, different dialects, different accents, and/or different viewpoints/biases.
