Abstract
Systems and methods for musical tempo detection are provided. The method includes detecting peaks and their locations in a waveform of a digital audio track, and dividing the track into first measures with a first-measure length based on a first estimated tempo. The method includes determining distances between a beginning of the first measures and each peak location, and determining a first number of peaks having the same distance from the beginning of the first measures. The method includes dividing the track into second measures with a second-measure length based on a second estimated tempo; determining distances between a beginning of the second measures and each peak location; and determining a second number of peaks having the same distance from the beginning of each of the second measures. The method includes estimating an accurate tempo by comparing the first number of peaks and the second number of peaks.
