Broader use of virtual reality environments and sophisticated
animations spawn a need for spatial sound. Until now, spatial sound
design has been based very much on experience and trial and error. Most
effects are hand-crafted, because good design tools for spatial sound
do not exist. This paper discusses spatial sound authoring and its
applications, including shared virtual reality environments based on
VRML. New utilities introduced by this research are an
inspector for sound sources, an interactive resource manager, and a
visual soundscape manipulator. The tools are part of a sound
spatialization framework and allow a designer/author of multimedia
content to monitor and debug sound events. Resource constraints
like limited sound spatialization channels can also be simulated.

For best results in the following demonstration, which contains HRTF-processed
sound, we recommend that you listen using high-quality stereo
If you need the files in a different format, let us know. We
tried to reduce the movie file size by reducing the image quality, but
for the audio we use full CD quality.
