Echo Nest Plugin¶
All attributes except
bpm are stored in flexible attributes (i.e., not
in files’ metadata).
See the Echo Nest’s page on acoustic attributes for a detailed description.

This plugin requires the pyechonest library in order to talk to the Echo Nest API. At least version 8.0.1 is required.
There are packages for most major linux distributions, you can download the library from the Echo Nest, or you can install the library from pip, like so:
$ pip install pyechonest
To transcode music for server-side analysis (optional, of course), install the ffmpeg command-line tool.
To get fingerprinting working, you’ll need to install the command-line
codegen tool for ENMFP or Echoprint, the two fingerprinting
algorithms supported by the Echo Nest. Please note that fingerprinting is not
convert is enabled, which is the default (but
it can be faster than uploading).
Beets includes its own Echo Nest API key, but you can apply for your own for
free from the Echo Nest. To specify your own API key, add the key to your
configuration file as the value for
echonest_tempo like so:
echonest: apikey: YOUR_API_KEY
In addition, the
auto config option lets you disable automatic metadata
fetching during import. To do so, add this to your
echonest: auto: no
echonest plugin tries to upload files to the Echo Nest server if it
can not be identified by other means. If you don’t want that, disable the
upload config option like so:
echonest: upload: no
The Echo Nest server only supports a limited range of file formats. The plugin
automatically converts unsupported files to
ogg. If you don’t want that,
convert config option like so:
echonest: convert: no
The Echo Nest server does not allow uploading of files with sizes greater than
50MB. The plugin automatically truncates large files to their first 5
minutes. If you don’t want that, disable the
truncate config option like
echonest: truncate: no
To enable fingerprinting, you’ll need to tell the plugin where to find the
Echoprint or ENMFP codegen binary. Use the
codegen key under the
echonest section like so:
echonest: codegen: /usr/bin/echoprint-codegen
In addition to running automatically on import, the plugin can also be run manually
from the command line. Use the command
beet echonest [QUERY] to fetch
acoustic attributes for albums matching a certain query.
