Document Type and Number:
WIPO Patent Application WO/2017/195292
Kind Code:
A1
Abstract:
Provided is a music structure analysis device (4) that allocates feature segments that characterize the structure of music data (M1) to music data (M1) in which development points are established in feature segments, wherein the music structure analysis device (4) includes: a position information acquisition unit (11) for acquiring the position information for the development points; a sound number analyzing unit (12) for analyzing a number of sounds with different frequencies for each segment between each of the development points on the basis of the position information for the development points acquired by the position information acquisition unit (11); and a feature segment allocation unit (15) for allocating the feature segments to a segment between other development points on the basis of the segment between development points determined to contain a local maximum value for the number of sounds analyzed by the sound number analyzing unit (12).
