本文介绍了一个用于提取和分析音乐中音高组织的模块化软件平台Tarsos。对于Tarsos，从音频信号生成基音估计，并且处理这些估计以形成在音乐上有意义的表示。Tarsos的目标是通过结合交互式用户界面、几种基音估计算法、过滤选项、即时听觉反馈和每一步的数据输出模式，为基音分析提供一个灵活的系统。为了研究最常用的音高，构建了一个细粒度的直方图，每个八度最多允许1200个值。这使得塔索斯能够分析西方音乐中的偏差，或者分析与许多非西方音乐中常见的12个音调相同的气质不同的特定音阶。Tarsos有一个图形用户界面，也可以使用API作为批处理脚本启动。因此，它既适用于单首歌曲的分析，也适用于大型音乐语料库的分析。该界面允许多种可视化表示，并可指示被分析对象的比例。提取的音阶可以立即用于调谐可以在发现的音阶中演奏的MIDI键盘。这些特点使Tarsos成为一个有趣的工具，可以用于音乐学分析、教学甚至艺术创作。
Abstract This paper presents Tarsos, a modular software platform used to extract and analyse pitch organization in music. With Tarsos pitch estimations are generated from an audio signal and those estimations are processed in order to form musicologically meaningful representations. Tarsos aims to offer a flexible system for pitch analysis through the combination of an interactive user interface, several pitch estimation algorithms, filtering options, immediate auditory feedback and data output modalities for every step. To study the most frequently used pitches, a fine-grained histogram that allows up to 1200 values per octave is constructed. This allows Tarsos to analyse deviations in Western music, or to analyse specific tone scales that differ from the 12 tone equal temperament, common in many non-Western musics. Tarsos has a graphical user interface or can be launched using an api—as a batch script. Therefore, it is fit for both the analysis of individual songs and the analysis of large music corpora. The interface allows several visual representations, and can indicate the scale of the piece under analysis. The extracted scale can be used immediately to tune a midi keyboard that can be played in the discovered scale. These features make Tarsos an interesting tool that can be used for musicological analysis, teaching and even artistic productions.
