Abstract
In the context of a video game, multimedia presentation or other application, multiple sound sample files are read out simultaneously and mixed together. The volumes and/or pitches of the wave tables are parameterized to allow a single parameter (e.g., power, intensity, etc.) to simultaneously control the multiple read out processes. The control parameter may be, for example, responsive to a user-manipulable control, such as a joystick. Sound effects produced using this technique are rich and interesting, and the user feels as if he or she is directly controlling the effect.
