从复调音乐录音中分离不同的声源构成了一项复杂的任务，因为人们必须考虑不同的音乐和声学方面。在过去的几年中，已经提出了各种分数通知程序，其中音乐线索，如音高，定时和轨道信息被用来支持源分离过程。在本文中，我们讨论了一个框架分解成notewise音频事件，作为基本的积木给定的音乐录音。特别是，我们引入了一个接口，采用额外的分数信息，为用户提供一个自然的方式来与这些音频事件进行交互。通过简单地选择乐谱内的任意音符组，用户可以访问、修改或分析给定音频记录中的对应事件。通过这种方式，我们的框架不仅为音频编辑应用程序开辟了新的途径，而且还可以作为评估和更好地理解源分离算法的结果的有价值的工具。
The separation of different sound sources from polyphonic music recordings constitutes a complex task since one has to account for different musical and acoustical aspects. In the last years, various score-informed procedures have been suggested where musical cues such as pitch, timing, and track information are used to support the source separation process. In this paper, we discuss a framework for decomposing a given music recording into notewise audio events which serve as elementary building blocks. In particular, we introduce an interface that employs the additional score information to provide a natural way for a user to interact with these audio events. By simply selecting arbitrary note groups within the score a user can access, modify, or analyze corresponding events in a given audio recording. In this way, our framework not only opens up new ways for audio editing applications, but also serves as a valuable tool for evaluating and better understanding the results of source separation algorithms.
