WIPO Patent Application WO/2019/043798
Kind Code:
A1
Abstract:
This song analysis device (1) is provided with: a beat interval acquisition unit (21) which acquires the beat interval in song data (AD); a candidate detection unit (24) which detects, as candidates for sound generation positions of a snare drum, sound generation positions where the amount of change in generated sound is equal to or greater than a prescribed threshold value in the song data (AD); and a sound generation position determination unit (25) which determines that the candidates for the sound generation positions in the song data (AD) for which a two beat interval is acquired by the beat interval acquisition unit (21), among the candidates for the sound generation positions of the snare drum, are the sound generation positions of the snare drum.
