In this paper we propose a template matching algorithm to address tempo tracking problem in MP3 domain. The algorithm is based on MP3 Window-Switching Pattern (WSP) only. This means that no frequency analysis is performed by the program itself. Because the WSP is structured coherently with the drums line it is possible to compare this pattern with a simple metronome template. Experimental results are presented for a range of different musical styles, including rock, jazz, and popular songs with a variety of BPM and time signature. A part of the experimentation is dedicated to analyze the train set proposed for MIREX 2006. A computational cost analysis is presented too.

Abstract
In this paper we propose a template matching algorithm to address tempo tracking problem in MP3 domain. The algorithm is based on MP3 Window-Switching Pattern (WSP) only. This means that no frequency analysis is performed by the program itself. Because the WSP is structured coherently with the drums line it is possible to compare this pattern with a simple metronome template. Experimental results are presented for a range of different musical styles, including rock, jazz, and popular songs with a variety of BPM and time signature. A part of the experimentation is dedicated to analyze the train set proposed for MIREX 2006. A computational cost analysis is presented too.
