Claim 0:
1. A method for determining an accurate measure length and a corresponding musical tempo of a digital audio track, the method comprising:
detecting a plurality of peaks and peak locations in a waveform of the digital audio track;
estimating a first tempo of said digital audio track;
dividing the digital audio track into a first plurality of measures, wherein the length of each of the first plurality of measures is based on the first tempo;
determining the distances between a beginning of each of the first plurality of measures and each peak location within said first plurality of measures;
determining a first number of peaks having the same distance from the beginning of each of the first plurality of measures containing each peak location;
estimating a second tempo of said digital audio track;
dividing the digital audio track into a second plurality of measures, wherein the length of each of the second plurality of measures is based on the second tempo;
determining the distances between a beginning of each of the second plurality of measures and each peak location within said second plurality of measures;
determining a second number of peaks having the same distance from the beginning of each of the second plurality of measures containing each peak location; and
determining whether the accurate measure length corresponds to the first tempo or corresponds to the second tempo by comparing the first number of peaks and the second number of peaks, wherein the accurate measure length corresponds to the first tempo when the first number of peaks is greater than the second number of peaks.
