RELIABLE, EFFICIENT AND LOW COST METHOD FOR GAMES AUDIO RENDERING

摘要

An efficient method for a reliable and accurate rendering of audio in a virtual reality environment, such as computer gaming. It excels other known rendering methods in its ability to achieve high quality audio rendering in real time conditions using a regular personal computer without any need for a special hardware accelerated audio card. A total of k physical properties are defined for the sound source and for the various objects that may affect the generation and distribution of the sound in the simulated environment. For each one of those physical properties some applicable values are predefined in a granularity which is a parameter of the method. This way a k dimensional grid of data points is defined. For each one of those data point the sounds that will be heard by the listener are offline calculated offline as reference samples. When the sound shall be generated in real time, for any given real data point, it is calculated as an interpolation of some near reference samples on the predefined k dimensional grid.
