MUSIC PIECE ORDER DETERMINATION DEVICE, MUSIC PIECE ORDER DETERMINATION METHOD, AND MUSIC PIECE ORDER DETERMINATION

摘要

A beat information corrector acquires beat position information including information regarding a point of time when a beat is reproduced, acquires a tempo value indicating a number of beats per unit time in a music piece, and corrects the beat position information of the music piece so that the tempo value of the music piece be a same value as the reference value. A correlation value calculator calculates a correlation value, which indicates a degree of correlation of beat position information between respective music pieces among a plurality of the music pieces, based on the corrected beat position information. A music piece order determiner determines a music piece order as a reproduction order of music pieces, which are to be reproduced successively, so that a product or total sum of the correlation values between the music pieces be at a maximum or an approximate solution thereof.

主权项

1. A music piece order determination device comprising:
a beat information corrector configured, in a case of reproducing a music piece, to acquire beat position information including at least information regarding a point of time when a beat is reproduced, to acquire a tempo value indicating a number of beats per unit time in the music piece, and to correct, in a case where the tempo value is different from a reference value, the beat position information of the music piece so that the tempo value of the music piece be a same value as the reference value; a correlation value calculator configured to calculate a correlation value based on the beat position information in which the tempo value is corrected to the same value as the reference value, the correlation value indicating a degree of correlation of beat position information between respective music pieces among a plurality of the music pieces; and a music piece order determiner configured to determine a music piece order as a reproduction order of music pieces, the music pieces being reproduced successively, so that a product or total sum of the correlation values between the music pieces be at a maximum or an approximate solution thereof.
