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

摘要

The audio design for virtual environments includes simulation of acoustical room propertis besides specifying sound sources and sinkds and theri behavior. Virtual environemnts supporting room reverberation not only gain realism but also provide additional infromation to the suer about surrounding space. Catching the different sound properties by the different spaces requires p[artitioning the space by the propertis of aural spaces. We define soundscape and aural attributes as an application and multimedia content interface. Caluated 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 rreverberation.
