(This post is dedicated to the Slavic readers who can’t get enough of the two censored anime pictures on this page.)

Hentai-Oto-Ma was made using
Coagula Light, a shareware “colour-organ” that interprets digital images as sound spectra (height=frequency, width=time). The image source for this piece was a pornographic Japanese manga comic: each digitally scanned frame of the comic was interpreted with five different, variable time-frames and pitch ranges. The five sequences of frames are played simultaneously, each subjected to different filtering and panning processes. In effect, the piece is a type of timbral canon, with the same series of tone structures transposed into different frequencies and durations – this can be heard most clearly at the end of the piece.
The left half of the picture above shows selected frames from the original comic. On the right is a spectrographic analysis of right channel of Hentai-Oto-Ma (0’28” to 0’39”) showing the images transformed across time and frequency.
