Perceptually Motivated Scoring of Musical Meter Classification Algorithms
Jean‐Pierre Martens, Matthias Varewyck · Journal of the Audio Engineering Society · 2010
In this paper, perceived confusions between the four most popular meters 2/4, 3/4, 4/4 and 6/8 in Western music are examined. A theoretical framework for modeling these confusions is proposed and translated into a perceptually motivated objective score that can be used for the evaluation of meter classification algorithms with respect to meter labels that were elicited from a single annotator. Experiments with three artificial and two real algorithms showed that the new score is preferable over the traditional accuracy since the score rewards algorithms that make reasonable errors and seems to be more robust against different annotators.
