<P>PROBLEM TO BE SOLVED: To evaluate the performance of natural musical instrument by evaluating a performance on the basis of not only information based on an MIDI(Musical Instrument Digital Interface) but also the waveform data of a sound. <P>SOLUTION: A performance evaluation device 1 creates evaluation reference data generated according to the performance of a musical piece, and composed of the combination of a parameter on a frequency axis and a parameter on a time axis on the basis of evaluation reference waveform data as the reference of evaluation, creates evaluation object data generated according to the performance of the musical piece, and composed of the combination of the parameter on the frequency axis and the parameter on the time axis on the basis of evaluation object waveform data as the object of evaluation, and calculates an evaluation value on the basis of the result of the comparison of the evaluation reference data and the evaluation object data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
