The Audio component creates an audio player with the ability to have the audio automatically start once the audio player comes into view.
Look at the Audio Component Demo
Title – Provide an optional heading for the audio player.
Audio URL – URL to the mp3 file. Click Select Media to open the WordPress Media Library.
Loop Audio Player – Enable the audio player to loop/repeat.
Start Audio When in View – When set to on, the audio will start playing automatically once scrolled into view.
Stop Audio When Out of View – Used together with the option above, this option, when set to on, will stop the audio player from playing once scrolled out of view.
Hide Audio Player – Hide the audio player by setting this to on. This is useful for looping audio effects that do not need user controls.
