Idea: Make a Fourier Analysis of the current sound file. Take the 10 loudest frequencies and display their representative colour. (according to octave is double the frequency and 440Hz is A). The coulours are also changing their brightness (how much white) according to their overall pitch. 20 Hz is black, 20 kHz is white.
