MUSICAL COMPOSITION CLASSIFICATION METHOD, MUSICAL COMPOSITION CLASSIFICATION DEVICE AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a musical composition classification method, a musical composition classification device and a computer program, capable of classifying a musical composition by an impression value which is matched closer to real impression when a person listened to the musical piece.;SOLUTION: The musical composition classification device of the invention performs the steps of: sampling a sound signal from a musical composition data (S1); obtaining a fluctuation data which characterizes fluctuation of a sound volume from a sound signal (S2); detecting a tempo of the musical composition (S3); calculates a mel-cepstrum coefficient from the sound signal (S4); converting the fluctuation data and the mel-cepstrum coefficient to the impression value for showing a specific impression degree which a person receives from the musical piece (S5); correcting the tempo by using the impression value (S6); and storing the impression value and the tempo by relating them to the musical piece data (S7). By calculating the impression value from the mel-cepstrum coefficient indicating sound quality for characterizing the musical composition, the impression value which is closer to impression felt by a user who actually listened to the music piece, is obtained.;COPYRIGHT: (C)2008,JPO&INPIT
