近年来，源分离一直是音乐信号处理的核心研究课题，其应用领域包括立体声到环绕声上混音、唱片骑师或制作人的混音工具、乐器均衡、卡拉 OK 系统以及音乐分析任务中的预处理。然而，音乐声源通常在时间和频率上密切相关，并且如果没有关于声源的额外知识，音乐录音的分解通常是不可行的。为了简化这项复杂的任务，最近提出了各种利用乐谱可用性的方法。乐谱提供的附加仪器和注释信息指导分离过程，从而显着提高分离质量和稳健性。利用这种丰富的信息源的一个主要挑战是弥合乐谱指定的高级音乐事件与其在录音中相应的声学实现之间的差距。在本文中，我们回顾了基于分数的源分离的最新进展，并讨论了整合由分数编码的先验知识的各种策略。
In recent years, source separation has been a central research topic in music signal processing, with applications in stereo-to-surround up-mixing, remixing tools for disc jockeys or producers, instrument-wise equalizing, karaoke systems, and preprocessing in music analysis tasks. Musical sound sources, however, are often strongly correlated in time and frequency, and without additional knowledge about the sources, a decomposition of a musical recording is often infeasible. To simplify this complex task, various methods have recently been proposed that exploit the availability of a musical score. The additional instrumentation and note information provided by the score guides the separation process, leading to significant improvements in terms of separation quality and robustness. A major challenge in utilizing this rich source of information is to bridge the gap between high-level musical events specified by the score and their corresponding acoustic realizations in an audio recording. In this article, we review recent developments in score-informed source separation and discuss various strategies for integrating the prior knowledge encoded by the score.
