Experiencing Audio and Music in a Fully Immersive Environment

Abstract
The UCSB Allosphere is a 3-story-high spherical instrument in which virtual environments and performances can be experienced
in full immersion. The space is now being equipped with high-resolution active stereo projectors, a 3D sound system with several
hundred speakers, and with tracking and interaction mechanisms.
The Allosphere is at the same time multimodal, multimedia, multi-user, immersive, and interactive. This novel and unique instrument will be used for research into scientific visualization/auralization and data exploration,
and as a research environment for behavioral and cognitive scientists. It will also serve as a research and performance space
for artists exploring new forms of art. In particular, the Allosphere has been carefully designed to allow for immersive music
and aural applications.
In this paper, we give an overview of the instrument, focusing on the audio subsystem. We give the rationale behind some of
the design decisions and explain the different techniques employed in making the Allosphere a truly general-purpose immersive
audiovisual lab and stage. Finally, we present first results and our experiences in developing and using the Allosphere in
several prototype projects.
