Spaciousness control for sound field recording and reconstruction

Abstract

Auditory Spaciousness' is a perceptual characteristic which has been recognized as being an important aesthetic feature of music presentations of various types. Most previous research has been focused on the identification of the physical parameters which are causally involved in the generation of listener spatial impression when auditioning music. The presence of lateral reflections has been identified as contributing to room spatial impression. Significantly, it has also been recognised that lateral reflections generate an inter-aural dissimilarity which is of primary importance for a spatial impression, and that inter-aural cross correlation (lACC) can therefore be used as an indirect spaciousness index.
