This bpm plugin lets you to get the tempo (beats per minute) of a song by tapping out the beat on your keyboard.
To use the bpm plugin, first enable it in your configuration (see Using Plugins).
Then, play a song you want to measure in your favorite media player and type:
beet bpm <song>
You’ll be prompted to press Enter three times to the rhythm. This typically allows to determine the BPM within 5% accuracy.
The plugin works best if you wrap it in a script that gets the playing song. for instance, with mpc you can do something like:
beet bpm $(mpc |head -1|tr -d "-")
This plugin is inspired by a similar feature present in the Banshee media player.
