Study of Sound Source Shape and Wideness in Virtual and Real Auditory Displays
MPEG-4 AudioBIFS currently can describe and present point sound sources (e.g. a flying insect or a distant sound source) but it can not describe sound sources that have a certain spatial dimension like a choir, an orchestra, a seafront or rain. Spatial wideness or tonal volume is however a very important perceptual aspect of real sound sources. We proposed in July 2002 to enhance the spatial illusion of virtual sound scenes by adding sound source wideness and shape to AudioBIFS. A core experiment then followed to study the usefulness of this proposal. The details of the experiments and conclusions are described in this document.
