This simple to use function hides images sounds. When played back though a spectrum analyser the image reappears. It is a technique which has been used previously by artists such as Aphex Twin, Venetian Snares and Nine Inch Nails.

The images are divided so one axis corresponds to time and the other corresponds to frequency space. The amplitude of each frequency is determined by the pixel intensity at that point.
