<hr><a name="_details"></a><h2>Detailed Description</h2>
Visualization module.
<p>
This is the recommended frontend for visualization plugins. You pass it audio frames in your format, and it will handle all format conversions, rendering and fps control. Visualizations are run in a separate process, so plugins can never make the calling application crash. <hr><h2>Typedef Documentation</h2>
