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).

Abstract: An edit-to-it function of an editing system allows an editor to combine linear editing with non-linear editing. A linear source, such as a magnetic tape, may be identified as an edit source, as well as already predigitized material. When the linear source is selected as an edit source, an edit-to-it file is created that indicates the status of the source--which portions are already digitized and which are not. The editor identifies an in-point on the edit and an in-point on the source. The source prerolls, as applicable, to the in-point and lays the shot into the edit while simultaneously recording the shot including a handle prior to the in-point into a digital storage device. When the editor identifies the end of the shot, either by a predetermined out-point or on-the-fly, the source stops and the recording terminates.

Abstract: In a magnetic recording and reproducing apparatus such as DAT, when recording an acoustic signal which is a series of recording information on a magnetic tape, a program start signal is recorded automatically at the start of recording. This program start signal indicates a program recording start position on an acoustic signal or the like. This program start signal can be additionally recorded in a magnetic tape in which a program has been already recorded. When the program start signal record button is pressed while reproducing the magnetic tape, plural recording areas including the recording area which has been reproduced at the time of pressing are reproduced repeatedly. A recording area to be recorded additionally may be arbitrarily specified in such plural recording areas being reproduced repeatedly. The front-rear relation of the specified recording area may be confirmed by lighting an indicator or by the change of reproduction level during repetitive reproduction action.

Abstract: When dubbing information from a first recording medium to a second recording medium, control information including a start ID is recorded at appropriate timing. For example, when the fourth music selection recorded on a CD is reproduced for recording on a magnetic tape, the reproducing operation is started at a position (4, 00, 36) (represented by data TNC, INDEX, and FRAME) preceding the start position (4, 01, 46) of the fourth music. When a position (4, 00, 40) is detected, a record directing signal for directing the recording of the start ID is output to a digital magnetic tape recorder selection. This ensures the recording of the start ID prior to the recording on the magnetic tape of the start position of the fourth music selection.
