该出版物提出了一种用于检测和分类真实的世界音乐信号中的无音高乐器的新方法。导出的信息是创建乐谱（即自动转录）和自动提取语义有意义的元数据（例如克里思和音乐节拍）的重要先决条件。该方法采用独立子空间分析，使用非负独立分量分析和先验子空间分析的原则。先验子空间分析的一个重要扩展是从信号本身识别振动仪器的频率子空间。频率子空间用作检测打击事件和随后对发生的乐器进行分类的信息。报告了40个手动转录的测试项目的结果。
This publication presents a new method for the detection and classification of un-pitched percussive instruments in real world musical signals. The derived information is an important pre-requisite for the creation of a musical score, i.e. automatic transcription, and for the automatic extraction of semantic meaningful meta-data, e.g. tempo and musical meter. The proposed method applies Independent Subspace Analysis using Non-Negative Independent Component Analysis and principles of Prior Subspace Analysis. An important extension of Prior Subspace Analysis is the identification of frequency subspaces of percussive instruments from the signal itself. The frequency subspaces serve as information for the detection of the percussive events and the subsequent classification of the occurring instruments. Results are reported on 40 manually transcribed test items.
