Detailed Description

A visual component to display a peak meter using OpenGL.

The PeakMeterViewer class shows a peak meter (such as levels of audio signals) in a graphical form. It uses two sets of vertices: one for the current peak and one for a peak memory reading. The meter is displayed as a vertical bar that moves based on the dB values of the signal.
