2006:Audio Tempo Extraction Results
Contents
Introduction
These are the results for the 2006 running of the Audio Tempo Extraction task set. For background information about this task set please refer to the 2006:Audio Tempo Extraction page.
The aim of the Audio Tempo Extraction task is to extract the perceptual tempi from audio recordings. We differentiate the notion of perceived tempo and notated tempo in this task. A test set of 140 recordings was used to evaluate the algorithms. Ground truths for each recording were extracted from multiple listeners. Algorithms were scored on their ability to extract the two dominant perceptual tempi from a piece of music, with each tempo in the ground truth given a perceptual salience from the listening tests. In this task, a P-score of 1.0 denotes perfect performance.
