INPUTS 1/2/3 SOURCE AUDIO MENU

The second stage of Undo is a multi-band expander that is designed to restore dynamic range to audio that has been excessively 
compressed. Each of the five bands of the expander has a corresponding psychoacoustic dynamics detector and a peak detector 
that examine the peak levels of the incoming audio, and based upon that information plus the settings of the various controls, 
tells the expander how much dynamic range to restore to the audio.
