From surround to true 3-D

Abstract

To progress from surround sound to true 3-D requires an updating of the psychoacoustical theories which underlie current technologies. This paper shows how J.J.Gibson’s ecological approach to perception can be applied to audio perception and used to derive 3-D audio technologies based on intelligent pattern recognition and active hypothesis testing. These technologies are suggested as methods which can be used to generate audio environments that are believable and can be explored.To progress from surround sound to true 3-D requires an updating of the psychoacoustical theories which underlie current technologies.
