| 合理的音乐特征库构建方法对于实现准确音乐检索具有重要意义.以基于内容音乐检索框架为基础,将音乐特征库的构建分为采用基音提取方法建库、采用乐谱信息建库和采用MIDI分析方法建库3种方式,并提出一种基音提取及后处理方法和MIDI分析方法实现音乐特征库的构建.实验结果表明,这两种建库方法是正确有效的,可以准确、快速地实现音乐特征库的构建. |

| Abstract: |
| Construct music feature database properly is significant to accurate music retrieval. On the foundation of content-based music retrieval framework, this paper divides the database construct methods into pitch extraction, score information and MIDI analysis method. It proposes a pitch extraction, post-processing methods and MIDI analysis methods to implement the database construction. Experimental results show that the two methods are correct and effective, could construct a music database accurately and rapidly. |
