MAST rhythm re-annotated subset

<p>In the work described in the paper <em><a href="http://archives.ismir.net/ismir2019/paper/000052.pdf">A dataset of rhythmic pattern reproductions and baseline automatic assessment system</a></em><a href="https://ismir2019.ewi.tudelft.nl/?q=accepted-papers"><em>&nbsp;(ISMIR, 2019)</em></a>, Falc&atilde;o et al. applied efforts on annotating a subset of the full <a href="https://zenodo.org/record/2620357#.XKLB39szZuQ">MAST rhythm&nbsp;dataset</a> with grades for a subset of performances.</p> <p>Out of a&nbsp;total of 1040 student submissions comprised by the original dataset, 80 performances (equally distributed between 20 references)&nbsp;were graded by annotators using a custom annotation tool. During this process annotators could play each&nbsp;<em>(reference, performance)</em>&nbsp;pair as many times as desired before deciding on&nbsp;one of the available assessments:&nbsp;<em>4-Perfect, 3-Minor errors, 2-Major errors, 1-Completely off.</em></p> <p><strong>Naming convention</strong></p> <p>This dataset is a collection of&nbsp;audio files, onset features and&nbsp;user-annotated data. Audio files are stored into the <em>Only Performances</em> and <em>Only References </em>folders, together with some extra files containing their original onsets, quantized onsets and scaling parameters&nbsp;(for more information regarding this auxiliary data, please check the paper). An indexed list of files (<em>listreferences </em>and<em> listperformances</em>) is also stored in&nbsp;each of these folders in order to allow for mapping between audio files and auxiliary data. Example:</p> <ul> <li>The 10th line&nbsp;in&nbsp;<em>Only Performances/MAST Onsets [Performances]&nbsp;</em>contains the pure onsets for the 10th audio file listed in the&nbsp;<em>Only Performances/listperformances&nbsp;</em>file (&#39;55_rhy2_per138459_pass.wav&#39;)</li> </ul> <p>Also, in order to check the reference which&nbsp;relates to a specific performance, one must also look for audio file names in the list of files: the <em>i-eth</em> audio file listed in&nbsp;<em>Only Performances/listperformances&nbsp;</em>is a specific performance whose reference is defined by&nbsp;the<em> i-eth</em>&nbsp;line of&nbsp;<em>Only References/listreferences.&nbsp;</em>Example:</p> <ul> <li>The 10th audio file listed in&nbsp;<em>Only Performances/listperformances&nbsp;</em>file (&#39;55_rhy2_per138459_pass.wav&#39;) is a performance whose reference is stored in the 10th line of&nbsp;<em>Only References/listreferences&nbsp;</em>(55_rhy2_ref162559.wav)</li> </ul> <p>Such convention is also applied to the folder that contains the annotations (<em>Performances Annotations</em>). Each one of the&nbsp;<em>annotator_<strong>X</strong>.txt </em>file lists the grades assigned by the <em><strong>X</strong>-ith</em> annotator, and the mapping between the assessments and their referred performances is indexed in&nbsp;<em>listfiles.txt</em></p>
