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.

Parameterized interactive control of multiple wave table sound generation for video games and other applications

An interactive dynamic musical composition real time music presentation video game system uses individually composed musical compositions stored as building blocks. The building blocks are structured as nodes of a sequential state machine. Transitions between states are defined based on exit point of current state and entrance point into the new state. Game-related parameters can trigger transition from one compositional building block to another. For example, an interactivity variable can keep track of the current state of the video game or some aspect of it. In one example, an adrenaline counter gauging excitement based on the number of game objectives that have been accomplished can be used to control transitions between more relaxed musical states to more exciting and energetic musical states. Transitions can be handled by cross-fading between one music compositional component to another, or by providing transitional compositions. The system can be used to dynamically generate a musical composition in real time. Advantages include allowing a musical composer to compose a number of discrete musical compositions corresponding to different video game or other multimedia presentation states, and providing smooth transition between the different compositions responsive to interactive user input and/or other parameters.
