This paper presents an automatic meter extraction system which relies on auto-correlation coefficients. The input format for music is MIDI, and we assume that a beat and its ocurrences in the musical sequence are known. As output, our algorithm provides a set of possible metric groupings sorted by a confidence criteria. The algorithm has been tested on several pieces of Rameau and results are encouraging.
