<h3>How to Enable the Fallback</h3>
<hr />
<p>
<strong>wavesurfer.js</strong> will automatically
fallback to HTML5 Media if Web Audio is not
supported. However, you can choose to use audio
element manually. Simply set the <code>backend</code>
option to <code>"MediaElement"</code>.
</p>
<p>
<pre><code>var wavesurfer = Object.create(WaveSurfer);
wavesurfer.init({
container: document.querySelector('#wave'),
backend: 'MediaElement'
});
</code></pre>
</p>
<h3>Pre-rendered Peaks</h3>
<p>
If you have pre-rendered peaks (on your server),
you can pass them into the <code>load</code>
function. This is optional–if you don't provide
any peaks,
<strong>waserver.js</strong> will first draw a
thin line instead of a waveform, then attempt to
download the audio file via Ajax and decode it
with Web Audio if available.
</p>
<p>
<pre><code>wavesurfer.load('example/media/demo.mp3');</code></pre>
</p>
<p>
