# Audio Language Default Metadata File

The `- pmm: audio_language` Metadata File is used to dynamically create collections based on the audio languages available in your library.

Example Collections Created:

![](../images/audio_language.png)

The below YAML in your config.yml will create the collections:
```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: audio_language
```


## Template Variables
Template Variables can be used to manipulate the file from the default settings which are provided. 

Note that the `templates_variables:` section only needs to be used if you do NOT want to use the default settings.

All [Shared Variables](../variables) are available as well as the additional Variables below which can be used to customize the file.

| Variable         | Description & Values                                                                                                                                                |

The below shows an example config.yml with all the template_variables set away from their defaults:

```yaml
libraries:
  Movies:
    metadata_path:
      - pmm: audio_language
        template_variables:
          exclude:
            - fr  # exclude French
          sort_by: title.asc
          collection_section: 20
          collection_mode: show_items
          use_other: false
