Turn audio amplitude into color. The bars represent one of the 100 positions in the audio input array. The color of the bars is audio amplitude for each position. Knob1 sets the history length for the audio input: max left is ‘no’ history (displays the current audio) and max right averages the amplitude over the last 20 values (this looks the smoothest, but not as responsive as max right). Use knob3 to set the vertical position to display either horizontal or vertical bars or a mix of both.
