Abstract

The authors develop a 4-pi sampling reverberator, named “VSVerb.” The VSVerb restores a 4-pi reverberant field by using information of dominant reflections, i.e. dominant virtual sound sources, which are captured in a target space. The distances, amplitudes and locations of virtual sound sources are detected from measured x, y, z sound intensities at the site, and they are translated into time responses. The generated reverb-effect by the VSVerb provides high flexibility in sound design of post-production works. In order to verify its practicability, reverb-effects at several positions in a virtual room of a video game are re-generated from a VSVerb data which is sampled at one position in a real room. Re-generated reverbs for in-game sounds are implemented into a Dolby Atmos compliant production flow, and their spatial impressions and sound qualities are listened to be checked.
