Abstract : |
We present a system which processes audio signals sampled from recordings of musical performances, and estimates the tempo at each point throughout the piece. The system employs a bottom-up approach to beat tracking from acoustic signals, assuming no a priori high-level knowledge of the music such as the time signature or approximate tempo, but rather deriving this information from the timing patterns of detected note onsets. Results from the beat tracking of several popular songs are presented and discussed. 1, |
