AutoBPM Plugin
==============
The ``autobpm`` plugin uses the Librosa_ library to calculate the BPM of a track
from its audio data and store it in the ``bpm`` field of your database. It does
so automatically when importing music or through the ``beet autobpm [QUERY]``
command.
Install
-------
To use the ``autobpm`` plugin, first enable it in your configuration (see
:ref:`using-plugins`). Then, install ``beets`` with ``autobpm`` extra
.. code-block:: bash
pip install "beets[autobpm]"
Configuration
-------------
To configure the plugin, make a ``autobpm:`` section in your configuration file.
The available options are:
- **auto**: Analyze every file on import. Otherwise, you need to use the ``beet
autobpm`` command explicitly. Default: ``yes``
- **overwrite**: Calculate a BPM even for files that already have a ``bpm``
value. Default: ``no``.
- **beat_track_kwargs**: Any extra keyword arguments that you would like to
provide to librosa's beat_track_ function call, for example:
.. code-block:: yaml
autobpm:
beat_track_kwargs:
start_bpm: 160
