Bpm audio detection Library

Question

I'm looking for a library that simplify tempo/bpm audio detection.

Something similar to this http://adionsoft.net/bpm/ , but to use on *NIX machines.

Any language, but preference goes to php, perl, python.

Answer 1

Not a library, but a single class: bpmdetect.{cpp,h} from Mixxx.

Answer 2

Better: http://www.vamp-plugins.org/download.html

Answer 3

Mixxx uses the BPMDetect class from the SoundTouch library for BPM Detection. There is also another opensource library called BPMDj which is harder to use but is more accurate.

I personally wouldn't rely on either though. Then again I am a hobbyist DJ so I tend to rely more on my ears.

EDIT

There is a much better OSS library called aubio. It can also do beat detection and onset detection.

Answer 4

Also, if you're already using the GStreamer library, there's the bpmdetect element as a part of the soundtouch plugin, a part of gstreamer-plugins-bad. The python gstreamer bindings are meant to be quite good.
