synaesthesia 2.4-5ubuntu1 (amd64 binary) in ubuntu vivid

 This is a program for representing music graphically, as a curuscating
 field of fog, stars and/or glowing lines. It is intended as a visual
 accompaniment to music. The representation goes beyond conventional
 freqency analysis displays by combining a fourier analysis with stereo
 positioning information, making it possible to distinguish individual
 intruments, vocalists or effects by location, shape and color.
 .
 Sound inputs can be obtained from a CD, line input, the ESD sound daemon
 or via piped-in PCM data.
