| 摘 要： | 基于音频相关属性信息进行检索的音乐检索系统具有较大的局限。近年来，基于旋律的音频检索技术的研究成为音频检索技术的热点课题，对单声道音频的旋律特征提取算法作了较深入的研究。本文在分析音乐旋律表达的基础上，研究多声道文件的旋律特征，提出了多声道文件的旋律提取方法，设计完成了面向多声道MIDI格式文件的基于哼唱的音频检索系统。结果表明，系统具有良好的检索功能。

| Abstract: | The research has been focused on melody-based music retrieval technology because of the limitation of the music retrieval system based on the relative audio property.Much attention has been paid on the arithmetic of single-channel audio's melody feature extraction.This paper discussed the music melody representation and multi-channel audio's melody feature.The method of multi-channel melody extraction and a query by humming(QBH) based audio retrieval system was set up.The experiment showed that the retrieva... |
