Made with Processing. The circle reacts to the volume of sound, in real time. The size of the circles can be changed to be more or less sensitive to sound. Stroke color and Fill color can be altered using Random R G B and Alpha. Each color channel is either set to Random(255) or can be set to 0. The fade rate can be changed as well.
