MP3 Window-switching Pattern Analysis for General Purposes Beat Tracking on Music with Drums

This work analyzes the dependency of the window-switching pattern versus: different encoders, bit rates and encoder quality features. We propose a simple template-matching algorithm to solve beat tracking contest in music with drums. This algorithm uses windows-switching pattern information only. Commonly in a beat-tracking system the window-switching pattern is used to refine the results of a frequency evaluation. Furthermore, this paper wants to demonstrates the reliability of the window-switching pattern to solve beat-tracking problem in music with drums independently from encoders, bit rates, encoders quality features and frequency analysis. This paper confirms the window-switching pattern is adequate information in a beat-tracking contest at every bit rate and for every encoder.
