- <h3>How to Enable the Fallback</h3>
- <hr />
- <p>
- You can choose to use an existing
- html5 audio or video element manually. Simply set the <code>backend</code>
- option to <code>"MediaElement"</code> and pass the media element as the first
- argument to wavesurfer.load(). Include an array of peaks as the second
- argument, the Web Audio API will not be used to render the peaks.
- </p>
- <p>
- <pre><code>var wavesurfer = WaveSurfer.create({
- container: document.querySelector('#waveform'),
- waveColor: '#A8DBA8',
- progressColor: '#3B8686',
- backend: 'MediaElement'
- });
- // Load audio from existing media element
- var mediaElt = document.querySelector('video');
- wavesurfer.load(mediaElt);</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>
- // init with an array of peak data.
- wavesurfer.load(mediaElt, [0.0218, 0.0183, 0.0165, 0.0198, 0.2137]);
- </code></pre>
- </p>
- <p>
- Press this button to see the same demo with pre-decoded peaks:
- <button class="btn btn-warning" data-action="peaks">
- Load with pre-rendered peaks
