本文提出了一种新的音乐音频源分离方法,利用乐谱中的信息来监督分解过程。提出了一种利用非负矩阵分解(NMF)的原始框架,其中分量最初是在具有时间和谐波约束的合成信号上学习的。使用BSS EVAL和PEASS评估工具箱,创建了具有手动对齐MIDI分数的多声道录音的新数据集(TRIOS),并将我们的分离结果与文献中的其他方法进行了比较。结果表明,对于所使用的各种仪器配置,BSS EVAL指标总体上有所改善。
In this paper we present a new method for musical audio source separation, using the information from the musical score to supervise the decomposition process. An original framework using nonnegative matrix factorization (NMF) is presented, where the components are initially learnt on synthetic signals with temporal and harmonic constraints. A new dataset of multitrack recordings with manually aligned MIDI scores is created (TRIOS), and we compare our separation results with other methods from the literature using the BSS EVAL and PEASS evaluation toolboxes. The results show a general improvement of the BSS EVAL metrics for the various instrumental configurations used.
