Abstract

See full text

A master device receives audio, down-mixes the audio to stereo if it is not already in stereo, and then up-mixes the stereo into as many channels as there speakers in the network. The up-mixing can be based on the number and locations of the speakers, which may be determined automatically using a real time location system such as ultra wide band (UWB) location determination techniques. The master device sends each speaker the stereo only, with each speaker also up-mixing the stereo into at least its own respective channel and in some cases into all N channels, selecting from the rendered “N” channels that result from the up-mix the channel indicated as being associated with the particular location of the particular speaker.
