Hi all! The beets-bpmanalyser plugin will help you with all those songs that you don’t have tempo(bpm) information on. It scans your songs with the aid of aubio and calculates the average tempo(bpm) value for them, storing it into your library and/or on your mediaFiles.
The first release is up and working. It is also published on PyPi so you can just do:
pip install beets-bpmanalyser
Activate and configure the usual way.
Note: Automatic tagging during import is not yet implemented so for now you will have to call the command manually.
