GFDatabase: A Database of Flute Playing Techniques

<p><em>GFDatabase</em> (Geidai Flute Database)<em> </em>is a collection of recordings for the training of models for the real-time recognition of flute playing techniques.</p> <p>The database includes recordings of two flute players, a professional and a semi-professional. It includes monophonic recordings of isolated pitches of 11 flute playing techniques: <em>aeolian, flatterzunge, key click, multiphonics, ordinario, pizzicato, play and sing, staccato, tongue ram, trill, and whistle tone.</em></p> <p>The professional player was recorded using seven microphones representing different typical studio performance recording sets (see table below) in studio A (a large recording studio) at Geidai, Tokyo University of the Arts. The recording was made using a 96kHz sampling rate and a resolution of 24 bits.</p> <table> <tbody> <tr> <td><strong>Microphone Model</strong></td> <td><strong>Distance from Source (cm)</strong></td> <td><strong>Height (cm)</strong></td> <td><strong>Number of Microphones</strong></td> </tr> <tr> <td>DPA 4099</td> <td>33</td> <td><em>same height as the flutist's head</em></td> <td>1</td> </tr> <tr> <td>DPA 4011</td> <td>80</td> <td><em>same height as the flutist's head</em></td> <td>1</td> </tr> <tr> <td>DPA 4011</td> <td>100</td> <td><em>same height as the flutist's head</em></td> <td>1</td> </tr> <tr> <td>DPA 4006</td> <td>140</td> <td>179</td> <td>2</td> </tr> <tr> <td>DPA 4006&nbsp;</td> <td>458</td> <td>277</td> <td>2</td> </tr> </tbody> </table> <p>The semi-professional player was recorded using two microphones in studio C (a small recording studio) at Geidai, Tokyo University of the Arts.
