Two prototypes of reactive environments.
Agency/Control - Prototype 1
Explorable reactive performing space
Premiered in Vapaan Taiteen Tila, Helsinki, May 2015.
Saturated space is a study prototype for an immersive performance in a reactive audio system based on acoustic feedback.
The system is constituted by a feedback network over four condenser microphones hanging from the ceiling and four loudspeakers scattered in an empty reverberant tunnel.
A performer can modify the relationship between microphones and speakers by moving around and interacting with the hanging microphones, thus perturbing the sonic response of the audio system as a whole.
Little by little the performer acts a facilitator, inviting the audience to become active, to move around and possibly interact consciously with the system displacing the other microphones.
Even just by moving around, with the absorbing properties of their bodies, the audience participates in reshaping the acoustic characteristics of the space and modifying the audio content of the loop.
Eventually, by manipulating the microphones, the content of the feedback loop can be further influenced.
Agency/Control - Prototype 2
Presented in STUK, Leuven, February 2016.
Spegelbild is an interactive sonic installation based on acoustic feedback and movement tracking. It constitutes the result of a short residency during the art festival Artefact and has been worked as a three artists’ collaboration within the festival’s HackLab.
Spegelbild has been conceived site-specifically for the STUK's double staircase, connecting the museum entrance with the cafeteria. The acoustic properties of the staircase, made of carbon-fibre, generate its sonic content and the passage of people affects its behavior.
Using a distance sensor and a webcam detecting the amount of movements, the behavior of the visitors is tracked and analyzed to control simple parameters in the feedback loop, modifying the sound of the installation. Moreover, two contact microphones placed on the resonating surfaces of the staircase, give additional informations via audio description of its signals.
The acoustic content of the installation depends entirely on the physical properties of the space and on the behavior of its visitors. The same system, in a different space, would exhibit completely different sonic qualities.
