Controlling Phantom Image Focus in a Multichannel Reproduction System
The focus of the phantom image of an anechoic sound source in a multichannel reproduction system can be determined through the manipulation of fundamental interchannel relationships. Through a series of listening tests, various functions controlling the channel amplitudes are evaluated for their accuracy and reliability in generating predictable impressions of image foci. The applicability of these findings to existing and future surround sound standards are discussed.
