mmmm another cool musical project about  how any suface could be an instrument: Touch Interfaces everywhere

This is kind of amazing: if you put a contact microphone on a hard surface and then process the sound in realtime, you can turn that surface into a touch screen…or a programmable musical instrument.

Zamborlin’s own words, here’s how the magic is accomplished:

Through gesture recognition techniques we detect different kind of fingers-touch and associate them with different sounds. In the video we used two different audio synthesis techniques:
- physic modelling, which consists in generating the sound by simulating physical laws;
- concatenative synthesis (audio mosaicing), in which the sound of the contact microphone is associated with its closest frame present in a sound database.
