A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the base pitch of the tone moving upwards or downwards, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower. (From Wikipedia).
To hear it's effects, play it over and over again.
wow very amazing audio illusion. I keep on playing it i hear a creepy sound. How did you manage to make this audio illusion?
