Created by Technical Earth (Mo H. Zareei + Jim Murphy), interference [dac] is an audiovisual installation that explores the combination and interaction of waveforms in one medium with those of another. In the installation, which includes a linear array of four miniature projectors  affixed to loudspeaker cones, sound waves affect light waves while analogue elements alter digital ones.

The projectors are configured to output a series of abstract lines and patterns that are inspired by Thomas Young's interference experiment which led to the wave theory of light. The projected patterns are blurred and disrupted as the projectors are rattled and trembled by the movement of the loudspeaker cones. This motion results in visual distortions that occur at audio rates, which are significantly faster than any available digital refresh-rate. Therefore, those experiencing interference [dac] perceive the images being processed in a manner impossible to achieve with digital techniques alone, and are immersed in a sensory-blurring audiovisual experience. In this way, interference [dac] explores the concept of wave interference, not only as a physical phenomenon, but also through the intermingling of different mediums as well as disparate modes of communication.
