public class EqualizerUI
extends javax.swing.JPanel
implements java.awt.event.ActionListener, javax.swing.event.ChangeListener

This class implements an equalizer UI.

The equalizer consists of 32 band-pass filters. Each band of the equalizer can take on a fractional value between -1.0 and +1.0. At -1.0, the input signal is attenuated by 6dB, at +1.0 the signal is amplified by 6dB.
