摘要:

音频到乐谱对齐旨在生成表演音频和给定作品的乐谱之间的准确映射。标准的校准方法基于动态时间规整(DTW),并采用手工制作的功能,无法适应不同的声学条件。我们提出了一种方法来克服这一限制,使用学习帧相似性的音频到分数对齐。我们专注于钢琴音乐的离线音频到乐谱对齐。对不同声学条件下的音乐数据的实验表明,我们的方法比使用手工特征的标准DTW方法实现了更高的对齐精度,并生成鲁棒的对齐,同时适应不同的域。

英文摘要:

Audio-to-score alignment aims at generating an accurate mapping between a performance audio and the score of a given piece. Standard alignment methods are based on Dynamic Time Warping (DTW) and employ handcrafted features, which cannot be adapted to different acoustic conditions. We propose a method to overcome this limitation using learned frame similarity for audio-to-score alignment. We focus on offline audio-to-score alignment of piano music. Experiments on music data from different acoustic conditions demonstrate that our method achieves higher alignment accuracy than a standard DTW-based method that uses handcrafted features, and generates robust alignments whilst being adaptable to different domains at the same time.
