the demon hidden in an aphex twin song.
the short, written out
in 2001, someone found a demon’s face hidden in a song by the electronic musician aphex twin.
it’s the second track on his 1999 single, windowlicker, and its title is an equation. near the end comes a burst of screeching noise.
turn that noise into a spectrogram, a picture of sound, and a face appears.
the man who found it called it a demon.
but his spectrogram squeezed the low notes together and stretched the high ones. soon after, a 19-year-old fan spaced them out like the keys of a piano.
it wasn’t a demon. it was aphex twin himself, grinning.
aphex twin had built the picture that way, with metasynth, a program that turns each row of an image into a note.
his face was already his trademark, on his covers and in his videos. this time he hid it in the music.
so we hid our name in the short’s sound too, in the faint hiss under the sign-off.
