Note Segmentation Based on Prior Knowledge of Music Score

摘要

This paper proposes a note segmentation method combining music score, aiming at the problem that cannot segmentmulti-tone music with more changes in intensity accurately. By extracting the envelope peak value of music signal andmatching it with note values and pitch information of musical score, the segmentation of notes is completed.Simulationresults show that the method based on the prior knowledge of value and pitch information of music score can not onlyrealize the segmentation of notes of continuous single tone music, but also be suitable for multi-tone music with strongand weak variations.
