Multi-context voice communication in a SIP/SIMPLE-based shared virtual sound room with early reflections
An improved prototype of the “voiscape” voice communication medium has been developed and subjectively evaluated. Voiscape enables natural and seamless voice communication by using sound to create a virtual “sound room” in which people, who are represented by different sounds, can move freely. It features low-delay motion-tracking spatial audio with simulated early reflections that produce out-of-head sound localization and sound distance expression.
