| 摘 要： | 从音乐检索的实际应用出发，构建了一个基于旋律的音乐检索系统。使用基于时域自相关测量的音调追踪算法进行音乐片段的旋律提取，评价了对于声学音乐信号的不同帧分割方法的实验。使用三步轮廓法（上升、下降、不变）描述音符问的音程，并用记录音程信息的字符串作为音乐片段旋律轮廓的表示方式。在字符串最大匹配算法的基础上提出了具有音乐合理性的近似匹配算法。

| Abstract: | A melody based music retrieval system was implemented proceeding from the practical application of music retrieval. Pitch tracking algorithm based on autocorrelation measurement in time domain was used to extract melody from music clips. Different acoustic musical signal frame segmentation approaches were evaluated. 3-level contour (up, down, same) was used to describe musical interval direction between notes and character strings recording the musical interval directions were used to represent the melody contour of music clips. Musically reasonable approximate matching algorithm was proposed based on maximum string matching algorithm. |
