TIV.lib：音乐音频音调描述的开源库
TIV.lib: an open-source library for the tonal description of musical audio
摘要：
在本文中，我们提出了TIV.lib，一个开源库的音乐音频信号的基于内容的音调描述。其主要新颖性依赖于基于离散傅里叶变换的感知启发色调间隔向量空间，从该空间计算多个瞬时和全局表示、描述符和度量-例如，和声变化、不和谐音、全音阶和音乐基调。该库是跨平台的，用Python和图形化编程语言Pure Data实现，可用于在线和离线场景。值得注意的是它在增强音乐信息检索方面的潜力，其中音调描述符是众多方法和应用程序的核心。
英文摘要：
In this paper, we present TIV.lib, an open-source library for the content-based tonal description of musical audio signals. Its main novelty relies on the perceptually-inspired Tonal Interval Vector space based on the Discrete Fourier transform, from which multiple instantaneous and global representations, descriptors and metrics are computed - e.g., harmonic change, dissonance, diatonicity, and musical key. The library is cross-platform, implemented in Python and the graphical programming language Pure Data, and can be used in both online and offline scenarios. Of note is its potential for enhanced Music Information Retrieval, where tonal descriptors sit at the core of numerous methods and applications.
