Claim:
A system for audio reproduction comprising: means for obtaining one or more audio signals that are representative of sounds occurring at a first location; means for communicating the audio signals from the first location to a second location of a person; means for determining a position of the head of the person in at least two dimensions at the second location by imaging the person; and plural means for reproducing an audio field at the second location from the audio signals, wherein sounds emitted by each means for reproducing are controlled based on the position of the head of the person, wherein the plural means for reproducing are arranged spaced apart and directed toward a center and wherein a particular one of the audio signals applied to a particular one of the means for reproducing is time delayed based on the position of the person to maintain equal arrival times of the sounds to the person as the person moves around to different locations at the second location, wherein a perceived volume of the sound by the person is equal and independent of the position of the head of the person as the person moves around the second location.
