Abstract

In a storage section, there are stored a plurality of music data sets of a given first format. Reproduction definition information defines reproducing order of a group of desired music data sets among the plurality of music data sets stored in the storage section. On the basis of the reproduction definition information, the music data sets of the first format defined by the reproduction definition information are read out from the storage section and automatically supplied as objects to be converted into a second format different from the first format. Then, the supplied music data sets of the first format are converted into music data of the second format. In this way, the music data sets of the first format can be readily converted collectively into music data of the second format.

Claims

1. A music data processing apparatus comprising:

a storage section storing a plurality of music data sets of a given first format;

an acquisition section that acquires reproduction definition information defining reproducing order of a group of desired music data sets of said first format among the plurality of music data sets stored in said storage section;

a supply section that, on the basis of the reproduction definition information acquired by said acquisition section, reads out, from said storage section, the desired music data sets defined by the reproduction definition information, and supplies the read-out music data sets as objects to be converted into a second format different from said first format; and

a conversion section that converts the music data sets of said first format, supplied by said supply section, into music data of said second format.

2. A music data processing apparatus as claimed in claim 1 which further comprises a range designation section that, per music data set of said first format, designates a range in the music data set to be reproduced, and wherein, per music data set of said first format and only for the range designated by said range designation section, said conversion section converts the music data set of said first format into a music data set of said second format.

3. A music data processing apparatus as claimed in claim 1 wherein each of the music data sets of said first format has management data attached thereto, and the management data includes data that designates a range in the music data set to be reproduced, and

wherein, per music data set of said first format and only for the range designated by said range designation section, said conversion section converts the music data set of said first format into a music data set of said second format.

4. A music data processing apparatus as claimed in claim 1 which further comprises a list creation section that creates new reproduction definition information defining reproducing order of a group of the music data sets of said second format converted by said conversion section.

5. A music data processing apparatus as claimed in claim 1 wherein said conversion section generates a succession of music data sets by sequentially arranging a plurality of music data sets of said second format obtained by converting the group of music data sets of said first format defined by the reproduction definition information.

6. A music data processing apparatus as claimed in claim 5 wherein, in generating the succession of music data sets by sequentially arranging the plurality of music data sets of said second format, said conversion section connects together the plurality of music data sets of said second format by performing a cross-fade process on every two adjacent ones of the music data sets of said second format.

7. A method for, on the basis of a plurality of music data sets of a given first format stored in a storage section, generating music data of a second format different from said first format, said method comprising:

a step of acquiring reproduction definition information defining reproducing order of a group of music data sets among the plurality of music data sets of said first format stored in the storage section;

a supply step of, on the basis of the reproduction definition information acquired by said step of acquiring, reading out, from the storage section, the desired music data sets defined by the reproduction definition information and then supplying the read-out music data sets as objects to be converted into said second format different from said first format; and

a step of converting the music data sets of said first format, supplied by said supply step, into music data of said second format.

8. A program containing a group of instructions for causing a computer to execute a procedure for, on the basis of a plurality of music data sets of a given first format stored in a storage section, generating music data of a second format different from said first format, said procedure comprising:

a step of acquiring reproduction definition information defining reproducing order of a group of music data sets among the plurality of music data sets of said first format stored in the storage section;

a supply step of, on the basis of the reproduction definition information acquired by said step of acquiring, reading out, from the storage section, the desired music data sets defined by the reproduction definition information and then supplying the read-out music data sets as objects to be converted into said second format different from said first format; and

a step of converting the music data sets of said first format, supplied by said supply step, into music data of said second format.
