论文摘要
在本文中，我们介绍了Tiv.lib，这是一个开源库，用于基于内容的音乐音频信号描述。它的主要新颖性取决于基于离散的傅立叶变换的感知启发的音调间隔矢量空间，从中计算出多个瞬时和全局表示，描述符和指标，例如，谐波变化，不和谐，diatonicition和音乐关键。该库是跨平台，在Python和图形编程语言纯数据中实现，可用于在线和离线场景中。值得注意的是它可以增强音乐信息检索的潜力，其中音调描述符位于众多方法和应用程序的核心。
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.
