Description

Grain Room is an interactive audiovisual installation with particle based granular audio. The core concept idea is that small particles can flow into the room and out of it, and sound is generated from the presence and interaction (e.g. collision) of the particles. The particles are visualized on a wall projection surface and the particle sounds can be heard through the speakers. Particles are inaudible when they are not in the room and momentary silences can occur. The audio processing will be multichannel (4 speakers positioned on the side of the wall on the floor level and 4 above them).

The installation starts to live when users enter and exit and move in the room. The flow of particles in or out starts whenever one of the two doors in the room is open. When the doors remain closed the particles are trapped inside the room (if all the particles have not flown out of the room). The opening of the doors is recognized with infrared sensors that are controlled by an Arduino. This data will be sent to Pure Data running on a computer. Pure Data controls the particle engine (generation, amount, position and collision of the particles, and of course the sounds) and sends data to Open Frameworks application to make synchronized visuals for the grains.

I’m planning to publicly show this work at the entrance hallway of Aalto ARTS during the Cumulus Association meeting and MediaLab demo day in the end of May.

Technology

Computer (preferably Macbook Pro or Mac Mini)
Audio Interface with 8 channel output
8 Genelec speakers
2 Projectors
1 Webcam
Arduino with 2 Infrared sensors

The project can be any application that involves the combination of different media with code. It should be interactive and/or generative. Special attention should be given to the concepts of sensoriality and experience.

The preferred programming environment for the projects is openFrameworks, and this will be the one I will give support to. However, you can use any other programming environment.

Please present your concepts by posting to this blog, before 27/4. Use the name of your project as title, and “Projects” and “MMA2012″ as post categories. Include graphics/sketches and a project synopsis (2-3 paragraphs of text). In case you prefer to post the concepts somewhere else, email me the link and I will post it to the blog.

The final projects should be presented 2 weeks later, on 11/5.

The main development environment for the course will be openFrameworks (http://www.openframeworks.cc/). Students should have previously attended the Software Studies for Media Designers course, or demonstrate having acquired equivalent skills. Students are required to plan, develop, document and present a project at the end of the course.

“Want to turn your mobile device into a musical instrument? Or equip your game with interactive audio, rather than canned samples? You can do it with Pure Data (Pd), an open source visual programming environment that lets you manipulate digital audio in real time. This concise book shows you how to use Pd—with help from the libpd library—as an easily embeddable and widely portable sound engine.”
