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

Thus, the room turns into an archive for voices. And only
under certain conditions the spoken words are released
again, encoded in spectrographic drawings. Through digital
sonification, the voices become audible.
