기본 주파수의 가중치에 기반한 다음 오디오 신호에 대한 멜로디 유무 판단과 스무드화

Abstract

In this paper, a new melody decision method and a smoothing process based on weight of fundamental frequency (F0) are proposed. Weight of each candidate F0 is obtained by predominant-F0 estimation system (M. Goto, 2003). The proposed melody decision method is more efficient and faster than previous decision methods. Also, the smoothing process increases the accuracy of melody estimation. Experimental results are comparable with results of previous F0 estimation methods based on harmonic models.
