  • Method and system for editing digital audio information with music-like parameters
    Patent number: 5792971
    Abstract: 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).
