The idea for the Sound Extrusions installation is based on creating an interacting living sound element in space inspired by natural organic shapes.
The organic-looking porcelain shapes are in fact an 8-channel audio installation creating interactive soundscape based on the position of the listener.
The actual use of porcelain crafting proved to be quite an exciting and innovative experiment in acoustics and porcelain design as well.
Most of the soundscapes are built around recordings from my live electronica performance project, the e-didjeridoo.
The first idea was to use 'data sonification' technique and sonify meteo data from the Australian East Coast to connect the organic porcelain elements with actual environmental variables (hence the original name the Sound Extrusions). Afterall I have decided to use direct interaction with the listeners within the space at The Edge lobby. One of the reasons was also the fact, that the meteo data rate of change is way lower, than would be needed for any musicaly perceived changes or soundscapes generated by the MAX/MSP patch.
As the interactive element tool was chosen the MAX/MSP jitter library in combination with a live webcam video stream. Video frames are analyzed for specific color changes in the frames compared to the floor color. The x and y axis is than translated into Ambisonic sound position. The rate of change is also continuously evaluated and sounds are triggered, when the acceleration exceeds a specific treshold.
The actual sounds are stored in two banks: the drone section and the solo sound themes. The solo sound themes are thrown into the soundscapes as spatialized elements each time acceleration exceeds set value. The drone section builds up the underlying vibe and mood of the soundscape, while the solo sound theme bank follows the movement and fast paced moves of the listener.
Extensive filter section allows the sound installation to 'be tuned' and reflect each shape resonant properties and overall sound EQ characteristics.
The project was realized as part of five months long artist in residence position at The Edge (Centre for Arts, technology & enterprise) in Brisbane, Australia.There the sound residency blog entries are also available online at the Edge website and the whole sound residency project is presented there as well.
