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

<p>This database presents acoustic impedance spectra measured on a G-key D&iacute;zi (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&rsquo;s typical playing range), for both with the membrane attached and without. Accompanying each fingering entry is the sound recording and corresponding audio spectra.</p> <p>&nbsp;</p> <p>An interactive graphical version of this database is also presented at <a href="https://acoustics.sutd.edu.sg/dizi-impedance/">https://acoustics.sutd.edu.sg/dizi-impedance/</a> &nbsp;</p> <p>&nbsp;</p> <p>The impedance measurements (using the &ldquo;<a href="https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fnewt.phys.unsw.edu.au%2Fjw%2Freprints%2FDickensSmithWolfe.pdf&amp;data=04%7C01%7Cyixian_tan%40sutd.edu.sg%7C7763bf2bc6eb4f9c849908da09080e5d%7C3476b776e9904f72b95062489831623d%7C0%7C0%7C637832227461557470%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&amp;sdata=AfSXOQEqxZxbz%2BPJ7ZnbtAuSZn6xF1YBBUmQenjRZmA%3D&amp;reserved=0">three-microphone two-calibration</a>&rdquo; 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.</p>
