Abstract: Implementation of Aural Attributes for Simulation of Room Effects in Virtual Environments

Kenji Suzuki, Yuji Nishoji, and Jens Herder. Implementation of Aural Attributes for Simulation of Room Effects in Virtual Environments, ACM Multimedia 2000, ACM, Los Angeles, October, 439-441, 2000.

The audio design for virtual environments includes simulation of acoustical room properties besides specifying sound sources and sinks and their behavior. Virtual environments supporting room reverberation not only gain realism but also provide additional information to the user about surrounding space. Catching the different sound properties by the different spaces requires partitioning the space by the properties of aural spaces. We define soundscape and aural attributes as an application and multimedia content interface. Calculated data on an abstract level is sent to spatialization backends. Part of this research was the implementation of a device driver for the Roland Sound Space Processor. This device not only directionalizes sound sources, but also controls room effects like reverberation.
