摘要:

合唱音乐分离是指提取语音部分的音轨(例如,女高音、女低音、男高音和男低音)。数据集的缺乏阻碍了对这一主题的研究,因为由于版权问题和数据集收集困难,以前的工作只能在几分钟的合唱音乐数据上进行训练和评估模型。在本文中,我们研究了使用合成的训练数据的声源分离任务,真正的合唱音乐。我们做出三个贡献:首先,我们提供了一个自动化的流水线,用于从乐器表现力的可控选项内的采样乐器插件合成合唱音乐数据。这从JSB Chorales数据集产生了一个8.2小时长的合唱音乐数据集,人们可以很容易地合成其他数据。其次,我们进行了一个实验,以评估多个分离模型上现有的合唱音乐分离数据集从以前的工作。据我们所知,这是第一个全面评估合唱音乐分离的实验。第三,实验表明,合成的合唱数据是足够的质量,以提高模型的性能在真正的合唱音乐数据集。这为合唱音乐分离研究提供了额外的实验统计和数据支持。

英文摘要:

Choral music separation refers to the task of extracting tracks of voice parts (e.g., soprano, alto, tenor, and bass) from mixed audio. The lack of datasets has impeded research on this topic as previous work has only been able to train and evaluate models on a few minutes of choral music data due to copyright issues and dataset collection difficulties. In this paper, we investigate the use of synthesized training data for the source separation task on real choral music. We make three contributions: first, we provide an automated pipeline for synthesizing choral music data from sampled instrument plugins within controllable options for instrument expressiveness. This produces an 8.2-hour-long choral music dataset from the JSB Chorales Dataset and one can easily synthesize additional data. Second, we conduct an experiment to evaluate multiple separation models on available choral music separation datasets from previous work. To the best of our knowledge, this is the first experiment to comprehensively evaluate choral music separation. Third, experiments demonstrate that the synthesized choral data is of sufficient quality to improve the model's performance on real choral music datasets. This provides additional experimental statistics and data support for the choral music separation study.
