复调音乐主旋律提取方法综述

摘要

主旋律提取在音乐检索、乐谱抄录、翻唱识别等领域具有广泛应用.复调音乐频谱结构复杂多样,音高变化范围广,因此复调音乐的主旋律提取较为困难.本文综述了复调音乐主旋律提取研究进展,对复调音乐主旋律提取方法进行分类,阐述了典型方法,介绍了主旋律提取的评价指标,给出了最新MIREX主旋律提取评测结果,说明了主旋律提取面临的主要挑战,并对主旋律提取技术发展方向进行了展望.%Melody extraction is to automatically extract the melody from a given piece of polyphonic music,and has been widely applied in music retrieval,score transcription,cover song identification and so on.Melody extraction from digital polyphonic music is reviewed in this paper.Firstly,the methods used for melody extraction are classified.Then,the representative methods are elaborated in detail,evaluation methodologies are presented,and the most recently MIREX melody extraction competition results are shown.Finally,the existing challenges are summarized,and the future research directions are provided.
