TIV.lib: An open-source library for the tonal description of musical audio. In: Evangelista G, editor. Proceedings of the 23rd International Conference on Digital Audio Effects (DAFx-20); 2020 Sep 8-12; Vienna, Austria.

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.application/pdfeng© 2020 António Ramires et al.
