wavesurfer.js

With wavesurfer.js you can create anything from an HTML5 audio player to a sophisticated DJ application.

Quick start

In HTML, include the minified script:

Create a container where the waveform is to appear:

<div id="waveform"></div>

In your JavaScript app, create a wavesurfer instance, passing the container selector along with some options:

var wavesurfer = WaveSurfer.create({
    container: '#waveform',
    waveColor: 'violet',
    progressColor: 'purple'
});

Finally, load the audio:

wavesurfer.load('audio.wav');
