Listening to Music Upside-Down

http://photosounder.com

In this video, we first load a sound into Photosounder, which is converted into an image. We first listen to that image by turning it back into a sound, then, by pressing buttons 180° and FLIP, we flip it vertically, as to make the image appear upside-down, and we turn that upside-down image into a sound, an 'upside-down' version of the original sound.

What it does is invert the notes of the tune, which creates a different sounding tune, but it also inverts the overtones, so the instruments also sound different. This effect is unique to Photosounder, which is the only program out there that treats sounds and music entirely as images.

Music from the South Park episode, Gnomes.
