Detailed Description

A viewer that displays and allows interaction with the delay effect's filter response.

This class uses an OpenGL line renderer to show the frequency response of the delay's filter. It supports dragging to modify filter cutoff and spread values. Observers implementing the Listener interface can respond to mouse drag delta movements.
