Abstract: A centralized master device receives audio, down-mixes the audio to stereo if it is not already in stereo, and then up-mixes (renders) 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 its respective channel.

Abstract: Audio spatial effects are provided using a spherical array of ultrasonic speakers, with the azimuth angle and, if desired, elevation angle demanded by a control signal from, for example, a game console being matched to the sonic axis of one of the speakers in the array to activate the matching speaker.
