The Norwegian Academy of Music launched their new web page and logo today. As part of the visual profile, they wanted to create a dynamic logo, continuously reflecting the activities at the school. I was asked to contribute to making this new dynamic logo dynamic, and we ended up basing the system on analysis of the sound of the school.
The system I have developed is based on microphones in the canteen and the two concert halls. The audio signals from the microphones are fed to an analysis program, which in turn sends three global and perceptual paramaters (sound level, sharpness, and noisiness) to the logo generator running at the web server. The logo generator interprets the three sound parameters, and modifies the shapes, sizes and colours of the graphical elements in the logo.
