Audio Shortcode

The Audio feature allows you to embed audio files and play them back using a simple Shortcode. This was added as of WordPress 3.6 and is used like this:

[ audio]

Note: Do not put space between “[” and “audio”.

You can also use build-in embeds and simply put the media file on its own line:

My cool content
http://my.mp3s.com/cool/songs/coolest.mp3
More cool content

Usage​

I have an old post that has an audio file in the Media Library attached to it, and I want to use the new shortcode:

[ audio]

Note: Do Not put Space between “[” and “audio”.

I have the URL for an MP3, from the Media Library or external, that I want to play:

[audio src="audio-source.mp3"]

I have a source URL and fallbacks for other HTML5-supported filetypes:

[audio mp3="source.mp3" ogg="source.ogg" wav="source.wav"]

Options​

The following basic options are supported:

src (string) (optional) The source of your audio file. If not included it will auto-populate with the first audio file attached to the post. You can use the following options to define specific filetypes, allowing for graceful fallbacks:

  • ‘mp3’, ‘m4a’, ‘ogg’, ‘wav’, ‘wma’

Default: First audio file attached to the post

loop (string) (optional) Allows for the looping of media.

  • “off” – Do not loop the media.
  • “on” – Media will loop to the beginning when finished and automatically continue playing.

Default: “off”

autoplay (string) (optional) Causes the media to automatically play as soon as the media file is ready.

  • “off” – Do not automatically play the media.
  • “on” – Media will play as soon as it is ready.

Default: “off”

preload (string) (optional) Specifies if and how the audio should be loaded when the page loads. Defaults to “none”

  • “none” – The audio should not be loaded when the page loads.
  • “auto” – The audio should be loaded entirely when the page loads.
  • “metadata” – Only metadata should be loaded when the page loads.

Default: “none”
