Method and apparatus for dynamically composing music and sound effects using a computer entertainment system

摘要

A computer entertainment system is disclosed for dynamically composing a music sound tract in response to dynamic and unpredictable actions and events initiated by a directing system in a way that is aesthetically appropriate and natural. The system includes a composition database having one or more musical sequences. One or more of the one or more musical sequences has one or more decision points. The decision points within the database comprise a composing decision tree, with the decision points marking places where branches in the performance of the musical sequences may occur. A sound driver interprets each decision point within the one or more musical sequences. The sound driver conditionally responds to the interpreted decision points depending on the unpredicted actions and events initiated by the directing system. It is also contemplated that the directing system may directly query the state of the sound driver and adjust the activities of the directing system based on the results of the query. Other direct commands may be initiated by the directing system for controlling the performance of the sound driver.
