public abstract class AudioVisualizer : Element

A baseclass for scopes (visualizers).

It takes care of re-fitting the audio-rate to video-rate and handles renegotiation (downstream video size changes).

It also provides several background shading effects. These effects are applied to a previous picture before the `render()` implementation can draw a new frame.
