MAST rhythm re-annotated subset

In the work described in the paper <em>A dataset of rhythmic pattern reproductions and baseline automatic assessment system</em><em> (ISMIR, 2019)</em>, Falcão et al. applied efforts on annotating a subset of the full MAST rhythm dataset with grades for a subset of performances. Out of a total of 1040 student submissions comprised by the original dataset, 80 performances (equally distributed between 20 references) were graded by annotators using a custom annotation tool. During this process annotators could play each <em>(reference, performance)</em> pair as many times as desired before deciding on one of the available assessments: <em>4-Perfect, 3-Minor errors, 2-Major errors, 1-Completely off.</em> <strong>Naming convention</strong> This dataset is a collection of audio files, onset features and 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 (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 each of these folders in order to allow for mapping between audio files and auxiliary data. Example: The 10th line in <em>Only Performances/MAST Onsets [Performances] </em>contains the pure onsets for the 10th audio file listed in the <em>Only Performances/listperformances </em>file ('55_rhy2_per138459_pass.wav') Also, in order to check the reference which 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 <em>Only Performances/listperformances </em>is a specific performance whose reference is defined by the<em> i-eth</em> line of <em>Only References/listreferences. </em>Example: The 10th audio file listed in <em>Only Performances/listperformances </em>file ('55_rhy2_per138459_pass.wav') is a performance whose reference is stored in the 10th line of <em>Only References/listreferences </em>(55_rhy2_ref162559.wav) Such convention is also applied to the folder that contains the annotations (<em>Performances Annotations</em>). Each one of the <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 <em>listfiles.txt</em>
