bpm-tools: Tempo analysis

The bpm-tools software is the result of some experiments I did into automatically calculating and tagging the tempo (in beats-per-minute) of music files.

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.

But, in general I have found this incredibly useful and flexible. 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.

Source code

The most recent release is bpm-tools 0.3 (21st May 2013)

There is a Git repository available:

$ git clone http://www.pogo.org.uk/~mark/bpm-tools.git

This software is licensed under the GPLv2.
