command-line tool to calculate tempo of audio


The bpm-tools commands are used to automatically calculate the tempo (in beats-per-minute) of music, optionally displaying an analysis and adding it to file 'tags'. The data from these tags can be especially useful for navigating a music library in DJ software such as xwax(1).

The bpm command implements the algorithm on raw data, but the most commonly used command is bpm-tag to tag the file with the tempo in bpm. The bpm-graph command will produce a plot of the results of the autocorrelation.
