This piece works with “machine listening” and it is programmed in Supercollider. It is a system that listens to incoming notes and analyzes them to return a series of related sounds. In the case of the piece, the system takes sound events generated live by a Paetzold (wind instrument) that, at the same time, coexists with a series of pre-recorded samples of the same instrument. The visual part runs on a system developed in OpenFrameworks. Through this a series of videos with textures of the depths of the sea and recorded videos of the Paetzold are modified and transformed. Both systems (visual and sound) communicate through OSC in audio-visual events that the instrumentalist changes in real time through a template designed in TouchOSC.
