With a framework, the control is inverted: the framework calls the developer's code. We start by creating an AudioContext instance inside which to manipulate our track: Next, we create constants that store references to our
,
, and
elements, and use the AudioContext.createMediaElementSource() method to create a MediaElementAudioSourceNode representing the source of our audio â the
element will be played from: Next up we include a couple of event handlers that serve to toggle between play and pause when the button is pressed and reset the display back to the beginning when the song has finished playing: Note: Some of you may notice that the play() and pause() methods being used to play and pause the track are not part of the Web Audio API; they are part of the HTMLMediaElement API, which is different but closely-related.
