The Audio Foam Cutter is intended to transform sound into styrofoam and similar materials. The device consists of a hot-wire cutter mounted on a servo motor that is controlled by audio signals. This combination allows users to cut the sound input vertically and in real-time into the material as it is passed through the machine. The resulting cutouts can be used to assemble casting molds or they can stand alone as tiny sound sculptures.
The Audio Foam Cutter was developed as part of the Sound Shifting project, which investigates concepts of three-dimensional representations of sound.
