bpm-tools: Calculate and Tag Tempo (beats-per-minute) of Audio

August 14, 2013

The bpm-tools is a command line tool to automatically calculate and tag the tempo (in beats-per-minute) of music files. It reliably detects the tempo of the vast majority of popular music I have used it with, and is a useful tool for DJs and use with xwax on Linux, and scripting on the command-line.

Right now the code serves as the best explanation of the algorithm — a relatively simple application of an autocorrelation by statistical sampling. As yet, there is no scientific comparison of the algorithm with others software.
