Dízi Fingering Dataset: Acoustic Impedance and Audio Spectra, with Sound Files

This database presents acoustic impedance spectra measured on a G-key Dízi (Chinese transverse flute): a total of 35 fingerings (both standard and alternative fingerings) for 24 semi-chromatic notes ranging from D5 to G7 (i.e. the instrument’s typical playing range), for both with the membrane attached and without. Accompanying each fingering entry is the sound recording and corresponding audio spectra.

An interactive graphical version of this database is also presented at https://acoustics.sutd.edu.sg/dizi-impedance/  

The impedance measurements (using the “three-microphone two-calibration” technique) were conducted at the Acoustics Lab, School of Physics, UNSW, Sydney Australia. The authors are grateful to John Smith and Joe Wolfe for hosting us. The acoustic impedance measurement hardware and software was developed by Paul Dickens and we used a version of the software subsequently modified by Noel Hanna.

本数据库收录了G调中国横笛（Dízi）的声阻抗谱（acoustic impedance spectra）测量数据：涵盖该乐器典型演奏音域（D5至G7）内的24个半音阶音，对应35种指法（含标准指法与替代指法），且分别记录了安装笛膜与未安装笛膜两种状态下的测量结果。每条指法条目均附带录音文件与对应的音频频谱。

本数据库还提供交互式可视化版本，访问地址为：https://acoustics.sutd.edu.sg/dizi-impedance/

本次声阻抗测量采用“三麦克风双校准”技术，于澳大利亚悉尼新南威尔士大学（UNSW）物理学院声学实验室完成。作者谨此感谢John Smith与Joe Wolfe的接待协助。声阻抗测量所用硬件与软件由Paul Dickens开发，本研究使用了经Noel Hanna后续修改的软件版本。
