This is a formatter, available on node display or in views.
It turns a uploaded file or an external URL into an HTML5 audio player. Also supports various other JS player libraries which you can download. You can turn lazy-loading of the file on or off.
Note: there is a default label added below the player, which is either the URL field description or actual address, if the former is missing. Override the audioplayer.html.twig template to remove this.
