A method and apparatus for processing sound sources to simulate environmental
effects
includes source channel blocks for each source and single reverberation block.
The source channel blocks include direct, early reflection, and late reverberation
blocks for conditioning the source feeds to include delays, spectral changes, and
attenuations depending on the position, orientation and directivity of the sound
sources, the position and orientation of the listener, and the position and sound
transmision and reflection properties of obstacles and walls in a modeled environment.
The outputs of the source channel blocks are combined and provided to single reverberation
block generating both the early reflections and the late reverberation for all
sound sources.
