Abstract: We are developing a communication medium called voiscape, which enables taking to people while selecting persons to talk by moving in a virtual "sound room". In the second prototype of voiscape called VPII, the FIR Method is used for low-delay HRTF filtering, the sound room - the range of motion - is identified with the room in acoustical cal-culation, and early reflections by the sound room walls are simulated. The early reflections produce out-of-head sound lo-calization and sound distance expression. We also implemented motion-tracking and interpolation algorithms into the spatialization method. VPII enabled a voice communication environment, in which speaker identification is easy, multiple conversation-contexts can be created in a room, and motions of users and objects in a sound room are natural and causes only small noises.
