Mirex 2012 Audio Audio Tempo Estimation Evaluation: Tempokreb

In this paper, a system is presented that simultaneously extracts downbeats, beats, tempo, meter and rhythmic patterns, using a Hidden Markov Model (HMM) framework. The basic structure of the model was proposed by Whiteley et. al [7] and was further modified by introducing a new observation model: Rhythmic patterns are learned from data way and make the model adaptable to the rhythmical structure of a certain kind of music. The MIREX tempo estimation evaluation shows average results measured by the P-score, but outperforms (together with GKC3) all other submissions between 2006 and 2012 in the category “both tempi correct”.
