# Xtractor (Beets Plugin)

The _beets-xtractor_ plugin lets you, through the use of the [Essentia](https://essentia.upf.edu/index.html) extractors,
to obtain low and high level musical information from your songs.

Currently, the following attributes are extracted for each library item:
`bpm`, `danceability`, `beats_count`, `average_loudness`, `danceable`, `gender`, `is_male`, `is_female`,
`genre_rosamerica`, `voice_instrumental`, `is_voice`, `is_instrumental`, `mood_acoustic`,
`mood_aggressive`, `mood_electronic`, `mood_happy`, `mood_sad`, `mood_party`, `mood_relaxed`, `mood_mirex`,
`mood_mirex_cluster_1`, `mood_mirex_cluster_2`, `mood_mirex_cluster_3`, `mood_mirex_cluster_4`, `mood_mirex_cluster_5`

## Installation

The plugin can be installed via:

```shell script
pip install beets-xtractor
```

> [!IMPORTANT]  
> Requires [beets 2.10.0](https://github.com/beetbox/beets/releases/tag/v2.10.0) or later.

Activate it by adding `xtractor` to the list of plugins in your configuration:

```yaml
plugins:
  - xtractor
```

### Install the Essentia extractors

You will also need the `streaming_extractor_music` binary extractor from the [Essentia project](#credits).
Please refer to the [official installation documentation](https://essentia.upf.edu/installing.html#compiling-essentia-from-source)
for the installation procedure for your OS. If you are stuck you can use
the [Issue tracker](https://github.com/adamjakab/BeetsPluginXtractor/issues). If you are compiling Essentia from source,
make sure you compile it with Gaia support (`--with-gaia`) otherwise will not be able to use the high level models.

### Download the SVM models

For computing the high-level descriptors you will need the prebuilt trained models for prediction. You need to download these from
here: [SVM Models](https://essentia.upf.edu/svm_models/). I suggest that you download the most recent beta5 version.
This means that your binaries must match this version. Put the downloaded models in any folder from which they can be
accessed.

## Configuration

All your configuration will need to go under the `xtractor` key. This is what your configuration should look like:

```yaml
xtractor:
  auto: no
  dry-run: no
  write: yes
  threads: 1
  force: no
  quiet: no
  keep_output: yes
  keep_profiles: no
  output_path: /mnt/data/xtraction_data
  essentia_extractor: /mnt/data/extractors/beta5/streaming_extractor_music
  extractor_profile:
    highlevel:
      svm_models:
        - /mnt/data/extractors/beta5/svm_models/danceability.history
        - /mnt/data/extractors/beta5/svm_models/gender.history
        - /mnt/data/extractors/beta5/svm_models/genre_rosamerica.history
        - /mnt/data/extractors/beta5/svm_models/mood_acoustic.history
        - /mnt/data/extractors/beta5/svm_models/mood_aggressive.history
        - /mnt/data/extractors/beta5/svm_models/mood_electronic.history
        - /mnt/data/extractors/beta5/svm_models/mood_happy.history
        - /mnt/data/extractors/beta5/svm_models/mood_sad.history
        - /mnt/data/extractors/beta5/svm_models/mood_party.history
        - /mnt/data/extractors/beta5/svm_models/mood_relaxed.history
        - /mnt/data/extractors/beta5/svm_models/voice_instrumental.history
        - /mnt/data/extractors/beta5/svm_models/moods_mirex.history
```

First of all, you will need adjust all paths. Put the path of the extractor binary in `essentia_extractor` and
substitute the location of the SVM models with your local path under the `svm_models` section. Finally, set
the `output_path` to indicate where the extracted data files will be stored. If you do not set this, a temporary path
will be used.
will be used.

**Note on shell tilde expansion**: Please note that you cannot use shell expansion on the `svm_models` (i.e.: do not use `~` for your home folder).
The entire section of `extractor_profile` is passed as-is to the essentia extractor binary and it will not do tilde expansion on your paths.
The rest of the path keys such as `essentia_extractor` and `output_path` are used by the plugin itself and it will take
care of expanding the tilde symbol (`~`) to the home directory of the user running the script.
care of expanding the tilde symbol (`~`) to the home directory of the user running the script.

By default both `keep_output` and `keep_profile` options are set to `no`. This means that after extraction (and the
storage of the important information) the profile files used to pass to the extractors, and the json files created by
the extractors will be deleted. There are various reasons you might want to keep these files. One is for debugging
purposes. Another is to see what else is in these files (there is a lot) and maybe to use them with some other projects
of yours. Lastly, you might want to keep these because the plugin only extracts data if these files are not present. If
you store them, on a successive extraction, the plugin will skip the extraction and use these files (they are named
by `mb_trackid`) - speeding up the process a lot.

The `force` option instructs the plugin to execute on items which already have the required properties.

The `threads` option sets the number of concurrent executions. By default this is set to 1.
If you remove this option or if you set it to 0 the number of CPU cores present on your machine will be used.
The extraction is quite a CPU intensive process so there might be cases when you want to limit it to just 1.

The `write` option instructs the plugin to write the extracted attributes to the media file right away. Note that only `bpm` is actually written to the media file, all the other attributes are flex attributes and are only stored in the database.

The `dry-run` option shows what would be done without actually doing it.

**NOTE**: Please note that the `auto` option is not yet implemented. For now you will have to call the xtractor plugin manually.

## Usage

Invoke the plugin as:

$ beet xtractor [options] [QUERY...]

For a more verbose reporting use the `-v` flag on `beet`:

$ beet -v xtractor [options] [QUERY...]

The plugin has also got a shorthand `xt` so you can also invoke it like this:

$ beet xt [options] [QUERY...]

The following command line options are available:

**--dry-run [-d]**: Only show what would be done - displays the extracted values but does not store them in the library.

**--write [-w]**: Write the values (bpm only) to the media files.

**--threads=THREADS [-t THREADS]**: The number of concurrently running executions.

**--force [-f]**: Force the analysis of all items (skip attribute checks).

**--count-only [-c]**: Show the number of items to be processed and exit. Extraction will not be executed.

**--quiet [-q]**: Run without any output.

**--version [-v]**: Display the version number of the plugin. Useful when you need to report some issue and you have to state the version of the plugin you are using.

These command line options will override those specified in the configuration file.
