Review comment (suggestion):
I think you can set like this
```suggestion
        json_data = self._search_json(
            r'<script id="original-content" type="application/json">\s*', webpage, 'content', audio_id)
```

and then return audio in return like this:
```
     'url': json_data['audio']
```

    get_element_html_by_id,

    strip_or_none,
    traverse_obj,
    try_call,
