Note onset detection using one semitone filter-bank for MIREX 2009

Abstract

The presented onset detection approach is a very simple method described in (Pertusa et al. LNCS 3773, 2005). An implementation in D2K was already submitted for MIREX 2005, yielding a relatively low success rate. However, probably there were some problems in the evaluation, as the mean distance between the detected and actual onsets was too high (about -22 ms). Therefore, the system has been reimplemented in C++ and submitted again for evaluation. The methodology and parameters are the same than those described in (Pertusa et al. LNCS 3773, 2005) and (MIREX 2005). The source code has also been released 1 for research purposes.
