# Soundcheck

> Use the built-in Soundcheck fact collector to expose track certification levels as facts, enabling cross-track dependency checks.

The Soundcheck integration is installed by default and doesn't require any configuration.

The Soundcheck fact collector exposes Soundcheck track certifications as facts. It provides facts for each Soundcheck track using the fact reference:
`soundcheck:default/track/:trackId` where `:trackId` is the identifier for the track whose certification is contained in the fact.

This enables the creation of [checks](../../checks) against an entity's certification level in other tracks.

Here is an example of a check using the Soundcheck fact collector:

```yaml theme={"theme":{"light":"github-light","dark":"dracula"}}
- id: is_level_one_certified_track_id
  rule:
    - factRef: soundcheck:default/track/track_id
      path: $.highestLevel.ordinal
      operator: greaterThanInclusive
      value: 1
  schedule:
    frequency:
      cron: '* * * * *'
    filter:
      kind: 'Component'
```

> Note: The Soundcheck collector does not support scheduling. If you'd like the check to execute periodically the check must have a schedule with filter.
> This is described in checks section [here](/docs/plugins/soundcheck/core-concepts/checks#schedule).
