# Content filters overview

> Configure which HTML elements are included or excluded from audio generation

You can use the API to configure which HTML elements should be included or excluded from audio generation.

For example, to exclude `<h2>` subheadings from audio generation, add a filter with `include: false`.

```json theme={null}
{
  "element_type": "h2",
  "include": false
}
```

Define filters by `element_type`, `element_class`, `element_id`, `element_data`, `element_xpath`, or `value`. Combine attributes for more targeted filters.

See [Content extraction](/docs-and-guides/integrations/content-extraction) for how content filters work with ingestion.
