하모닉 집단화를 이용한 다성 음악에서의 멜로디 추출 구현

With the proliferation of digital music, study on signal processing of music is increasing. This paper presents the implementation of melody extraction from polyphonic music using harmonic structure grouping. For this we extract significant peaks in each frame and then determine the candidates for fundamental frequency by horminic structure. Then, we group the candidates by classification of equivalent MIDI note. Finally, we extract fundamental frequency using the pitch tracking based on ranking of candidates for fundamental frequency and continuity of fundamental frequency.
