interference [dac] BY Technical Earth

“interference [dac]” is an audiovisual installation that explores the combination and interaction of waveforms in one medium with those of another. In the installation, sound waves affect light waves while analog elements alter digital ones. The work consists of a pair of miniature projectors, each affixed to a loudspeaker cone. The projectors are configured to output a series of abstract lines and patterns that are inspired by Young’s interference experiment—an experiment by the scientist Thomas Young 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 that 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 media, as well as disparate modes of communication.
Technical Earth is a collaborative project between artists Mo H. Zareei (Iran) and Jim Murphy (USA).


Nabshi Center


Technical Earth is a collaboration between Mo H. Zareei and Jim Murphy, with a focus reductionist audiovisual elements that draw inspiration from physical, engineering, and design principles. Zareei (from Tehran) and Murphy (from New Mexico) both have educational backgrounds in the sciences (physics and geology). They both studied Music Technology at California Institute of the Arts, and are now based in Wellington, New Zealand. In Wellington, they are lecturer/researchers at Victoria University of Wellington, having completed their PhD studies in the Sonic Arts program. Through Technical Earth, they continue to develop new works that bring together stripped-down audio, video, and mechanical components into new inter-media collisions.
