在本文中，我们提出了一种新的算法自动分析，转录，参数提取孤立的复调吉他录音。除了一般的分数相关的信息，如注意开始，持续时间和音高，instrumentspecific信息，如弹拨字符串，应用弹拨和表达风格自动检索。为此，我们采用了几种最先进的方法来进行起始和偏移检测，多音高估计，字符串估计，特征提取和多类分类。此外，我们研究了一个强大的部分跟踪算法的不和谐性，广泛提取的新的和已知的音频功能，以及利用基于仪器的知识的形式，plausability过滤，以获得更可靠的预测。我们的系统实现了非常高的精度值98%的起点和偏移检测以及多音高估计。对于乐器相关的参数，该算法也表现出非常好的性能，准确率为82%的字符串数量，93%的采摘风格，83%的表达风格。索引术语-演奏技术，弹拨风格，表达风格，多基频估计，弦分类，指板位置，指法，电吉他，不和谐系数，指法
In this paper we present a novel algorithm for automatic analysis, transcription, and parameter extraction from isolated polyphonic guitar recordings. In addition to general score-related information such as note onset, duration, and pitch, instrumentspecific information such as the plucked string, the applied plucking and expression styles are retrieved automatically. For this purpose, we adapted several state-of-the-art approaches for onset and offset detection, multipitch estimation, string estimation, feature extraction, and multi-class classification. Furthermore we investigated a robust partial tracking algorithm with respect to inharmonicity, an extensive extraction of novel and known audio features as well as the exploitation of instrument-based knowledge in the form of plausability filtering to obtain more reliable prediction. Our system achieved very high accuracy values of 98 % for onset and offset detection as well as multipitch estimation. For the instrument-related parameters, the proposed algorithm also showed very good performance with accuracy values of 82 % for the string number, 93 % for the plucking style, and 83 % for the expression style.
