摘要

PROBLEM TO BE SOLVED: To prepare partial music data for preparing retrieval keys of music data, by automatically time-normalizing the music data of an arbitrary part.;SOLUTION: A time for sounding a single sound to be made is extracted, to determine the time which serves as the base therein; the time for sounding each sound is turned into a relative value by the time which is made the base, redundantly divided into partial data of a fixed length partly overlapped, on the basis of a reproduction time normalizing the music data; and the data amount of the partial music data is adjusted, on the basis of a difference of the calculated data amount.;COPYRIGHT: (C)2005,JPO&NCIPI
