Psychoacoustic Decoders for Multispeaker Stereo and Surround Sound

This paper overviews a new generation of multispeaker directional sound reproduction technology, based on maximizing the number of sound localization cues heard by a listener that are consistent with one another. The paper describes methods for optimizing the presentation of conventional and 3-channel stereo via three to five front-stage speakers, and new -ambisonic- decoders giving enhanced frontal-stage image stability for five- and six-speaker surround sound. Applications are discussed, including those for HDTV sound.
