Audio Graffiti is a multi-user music installation that explores new modes of sonic interaction, afforded by the latest in locative technologies. Several mobile users may create and explore a gradually evolving collage of audio recordings, “stuck” to real walls in urban environments.
The piece can be deployed in an outdoor environment (using GPS tracking), or in an indoor space as seen in the video below. Equipped with a wireless headset and tracking device, participants can “tag” or “spray” sound onto the wall. We provide several small musical instruments, which can be used along with one’s voice, to add sounds to the collaborative musical mix. The installation is seeded with some pre-existing sonic material, which allows participants to synchronize rhythmically, and maintains cohesion over time. All user-contributed sounds slowly fade away, resulting in an ever-evolving musical piece.
As users moves about, they also experience a changing sonic perspective of the localized sounds, based on their particular location. So users not only create audio content, but they also participate actively in the encounter (remixing) of sonic material. Participants who are waiting their turn in the staging area may watch a real-time 3D visualization of the installation, which shows avatars of each player walking amongst virtual sound sources.
This installation was filmed at the 12th Biennial Arts and Technology Symposium in the lobby of the Ammerman Center for Arts and Technology (Connecticut College, March 4-6, 2010).
