Evaluation method

Two accuracy measures have been computed:

This was motivated by the fact that, in the words of their very authors, tempo induction state-of-the-art algorithms commonly suffer confusions of metrical levels.

In addition, the 2 previous accuracy measures have been computed on part of the test data (the song excerpts) distorted by several processes: downsampling/resampling, gsm encoding/decoding, filtering, volume change, addition of reverberation and white noise (with a signal-to-noise ratio of 20 dB).
