Behavior

The amp-audio component loads the audio resource specified by its src attribute at a time determined by the runtime. It can be controlled in much the same way as a standard HTML5 audio tag. Like all embedded external resources in an AMP file, the audio is "lazily" loaded, only when the amp-audio element is in or near the viewport

The amp-audio component accepts up to three unique types of HTML nodes as children:

  • source tags: Just like in the HTML <audio> tag, you can add <source> tag children to specify different source media files to play.
  • a placeholder for before the audio starts: One or zero immediate child nodes can have the placeholder attribute. If present, this node and its children form a placeholder that will display instead of the audio. A click or tap anywhere inside of the amp-audio container will replace the placeholder with the audio itself.
  • a fallback if the browser doesn’t support HTML5 audio: One or zero immediate child nodes can have the fallback attribute. If present, this node and its children form the content that displays if HTML5 audio is not supported on the user’s browser.

For example:

<amp-audio width="400" height="300" src="https://yourhost.com/audios/myaudio.mp3">
  <div fallback>
    <p>Your browser doesn’t support HTML5 audio</p>
  </div>
  <source type="audio/mpeg" src="foo.mp3">
  <source type="audio/ogg" src="foo.ogg">
</amp-audio>

Attributes

src

Required if no <source> children are present. Must be HTTPS.

autoplay

If present, the attribute implies that the audio will start playing as soon as it is ready.

loop

If present, the audio will automatically loop back to the start upon reaching the end.

muted

If present, will mute the audio by default.

controlsList

Same as controlsList attribute of HTML5 audio element. Only supported by certain browsers. Please see https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/controlsList for details.

common attributes

This element includes common attributes extended to AMP components.

Media Session Attributes

amp-audio implements the Media Session API enabling developers to specify more information about the audio file that is playing to be displayed in the notification center of user's devices (along with play/pause controls).

artwork

URL to a PNG/JPG/ICO image serving as the audio's artwork. If not present, the MediaSessionAPI Helper will use either the image field in the schema.org definition, the og:image or the website's favicon.

artist

(string) indicates the author of the audio

album

(string) indicates the album the audio was taken from

title

(string) part of the common attributes, doubles as the audio's name displayed in the MediaSession notification. If not provided, the MediaSessionAPI Helper will use either the aria-label attribute or fall back to the page's title.

Example:

<amp-audio width="400" height="300"
  src="https://yourhost.com/audios/myaudio.mp3"
  artwork="https://yourhost.com/artworks/artwork.png"
  title="Awesome music" artist="Awesome singer"
  album="Amazing album">
  <source type="audio/mpeg" src="foo.mp3">
</amp-audio>
