Introduction

These are the results for the 2007 running of the Audio Onset Detection task set. For background information about this task set please refer to the 2007:Audio Onset Detection page.

The aim of the Audio Onset Detection task is to find the time locations at which all musical events in a recording begin. The dataset consists of 85 recordings across 9 different "classes" (e.g. solo drums, polyphonic pitched, etc.). For each sound file, ground truth annotations produced by 3-5 listeners were used for the evaluation. Each algorithm was tested across 10-20 different parameterizations (e.g. thresholds) in order to produce Precision vs. Recall Operating Characteristic (P-ROC) curves. The primary evauluation metric used was the F1-Measure (the equal weighted harmonic mean of precision and recall).

  • Note: There were a few faulty ground truth annotations in the 2005 and 2006 runs of this task. These have been removed for this year's evaluation. Thanks to Dan Stowell for finding these.
