The Shepard Scale: An Amazing Auditory Illusion

[compact]

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.

(Nihad Tule's remix is also great)

I don't know if it's the same illusion, but for me it's pretty similar.
