## Features

### AutoPlay

When `AutoPlay` is enabled, playback begins automatically once possible, without waiting for complete file download.

{% hint style="warning" %}
The user must interact with the page first before audio can be played. See <https://developers.google.com/web/updates/2017/09/autoplay-policy-changes#webaudio>
{% endhint %}

### Controls

Browser-provided controls enable users to manage playback, volume, and seeking.
