Concepts of Perceptual Significance for Composition and Reproduction of Explorable Surround Sound Fields
MetadataShow full item record
Recent work in audio and visual perception suggests that, over and above sensory acuities, exploration of an environment is a most powerful perceptual strategy. For some uses, the plausibility of artificial sound environments might be dramatically improved if exploratory perception is accommodated. The composition and reproduction of spatially explorable sound fields involves a different set of problems from the conventional surround sound paradigm, developed to display music and sound effects to an essentially passive audience. This paper is based upon contemporary models of perception and presents proposals for additional spatial characteristics beyond classical concepts of three-dimensional positioning of virtual objects.
