摘要： An embodiment of a system to synchronize data streams is described. During operation, the system receives a first data stream having a first data type and performs a sequence of operations on at least a portion of the first data stream. Next, the system stores metadata associated with the first data stream one or more times during the sequence of operations. Metadata can include a time stamp, data-stream information associated with the portion of the first data stream, and event information associated with the occurrence of one or more events during the sequence of operations. Moreover, the system provides a notification based on the stored metadata, the notification to facilitate synchronizing the first data stream with a second data stream having a second data type.

摘要： The present invention provides a method for editing digital audio information, such as musical material. Original musical parameters (302) are extracted and/or inputted from recorded original digital audio material (300). The original musical parameters (302) are then edited. The resulting edited musical parameters (304) are compared to the original musical parameters (302) to provide time varying control functions (308, 310, 312). The original digital audio material (300) is then processed with signal processing algorithms (314, 316, 318) which are controlled by the time varying control functions (308, 310, 312). This processing changes the original digital audio material (300) into new digital audio material (320) having musical characteristics which correspond to the edited musical parameters (304).
