本文提出了一种利用乐谱知识进行混合音乐中单声道声源分离的新方法。该信息用于初始化基于非负矩阵分解(NMF)计算频谱图的参数分解的算法。该算法提供时频掩码，利用维纳滤波分离信源。
In this paper we present a new technique for monaural source separation in musical mixtures, which uses the knowledge of the musical score. This information is used to initialize an algorithm which computes a parametric decomposition of the spectrogram based on non-negative matrix factorization (NMF). This algorithm provides time-frequency masks which are used to separate the sources with Wiener filtering.
