DIREZIONI INTERACTIVE SYSTEM FOR REAL TIME SOUND SPATIALIZATION THROUGH INFRARED SENSORS AND CONDUCTING BATON
1. [ DIREZIONI ] is a multimedia system for sound distribution in space, an installation that allows accurate sound spatialization in real time. [ DIREZIONI ] is regulated by infrared sensors and can be controlled by the gestures of a directional rod or by the movements of the phalanxes of a hand; for the elegance of the gesture the use of the conducting baton is preferred. [ DIREZIONI ] is a system adaptable to any acoustic space and / or art show; musical pieces and soundscapes are recorded and expressly composed for the theme of the exhibition / happening. It is also a self-sufficient system, able to reveal itself as a separate sound installation. [ DIREZIONI ] is a modular system and can be adapted to any configuration of loudspeakers, from the binaural listening up to the Ambisonics three-dimensional diffusion systems that use dozens of speakers. The speakers may also be different in shape and sound power; they are positioned ad hoc for each single event, in order to obtain the best sound performance in the considered space.
2. [ DIREZIONI ] has been programmed with the Cycling74 Max7 software and uses the Leap Motion infrared sensor, a conducting baton and the OSC Motion data communication software. Leap Motion is a small USB device that, thanks to the use of 3 LEDs and 2 infrared cameras, is able to observe a semi-spherical area of about one meter in diameter. The movements of the conducting baton above the sensors allow real-time interaction with the sound installation.
3. The audio speakers are arranged in circular mode, or scattered in the room (the so-called Acousmonium), with the directional station in the middle of the room. The audience becomes the director of the speakers' orchestra, protagonist of the installation, fully involved in the sound environment, choosing which audio contributions bring out. [ DIREZIONI ] combines the playful moment with active listening, making it possible the concentration on the sound element, in order to perceive its directions and intensities in space. The different loudness levels of the speakers are associated to the movements of the baton, picked up by the Leap Motion. Additional commands, which can be activated from the keyboard or MIDI Controller, enable additional real-time audio effects and alternative spatializations.
