Spectrograms are 'vocal fingerprints' of a person. Audio recordings of voices appear in form of hand-drawn spectrograms on the walls of a room in ultraviolet light.

Thus, the room turns into an archive for voices. Only under certain conditions and by use of a sonification technique the spoken words encoded in the spectrographic drawings are released again.

technics: UV-color, sonification: web-cam, pure data

Video: lyrics: Verena Dürr, Der verbindliche Klang (extracts)
