Assessment of State-of-the-Art Meter Analysis Systems with an Extended Meter Description Model.

An extended meter description model capturing the hierarchical metrical structure of Western music is proposed.The model is applied for the quantitative evaluation of four state-of-the-art automatic meter analysis algorithms of musical audio.Evaluation results suggest that the best beat trackers reach a reasonable level of performance, but that none of the tested algorithms has the potential to perform a reliable bar onset tracking.Moreover, the frontends of the best over-all systems not necessarily seem to have the front-ends best encoding the time signature in their output.Therefore, further improvements of these systems should be attainable by a better combination of ideas that can be borrowed from existing algorithms.
