<h4>Regions Plugin</h4>
|
|||
|
|
|
|||
|
|
<p>Regions are visual overlays on waveform that can be used to play and
|
|||
|
|
loop portions of audio. Regions can be dragged and resized.</p>
|
|||
|
|
|
|||
|
|
<p>Visual customization is possible via CSS (using the selectors
|
|||
|
|
<code>.wavesurfer-region</code> and <code>.wavesurfer-handle</code>).</p>
|
|||
|
|
|
|||
|
|
<p>To enable the plugin, add the script <code>plugin/wavesurfer.regions.js</code> to
|
|||
|
|
your page.</p>
|
|||
|
|
|
|||
|
|
<p>After doing that, use <code>wavesurfer.addRegion()</code> to create Region objects.</p>
|
|||
|
|
|
|||
|
|
