Abstract
This invention describes the use of dynamic sound source and listener position (DSSLP) based audio rendering to achieve high quality audio effects using only a moderate amount of increased audio processing. Instead of modeling the audio system based on sound and listener position only, the properties that determine the final sound are determined by the change in listener relative position from the current state and last state. This storage of the previous state allows for the calculation of audio effects generated by change in relative position between all sound sources and listener positions.
