Sound Visualization: Phase Modulation (Installation)  – 2014

Cymatics is the study of visible sound and vibration, a subset of modal phenomena.  When sound travels through a medium such as water, regions of maximum and minimum displacement are made visible. The resulting patterns emerge depending on the amplitude/frequency of the sound, as well as the density of the material and resonance of the enclosure. This installation utilizes two equidistant 8″ full-range speakers and a plate bi-amplifier housed in a custom rectangular box made of pine and plywood.  A thin sheet of acrylic is placed directly on top of the speaker cones and sealed with waterproof caulk.  The sounds used to create the patterns are generated using Phase Modulation synthesis.  This installation was presented at the CalArts Digital Arts Expo (2014) and the NMASS Festival (2014) in Austin, Texas.  Follow this Vimeo link for video.

Multi Laser Gestural Interface: MLGI (Musical Interface) – 2009

The MLGI is a gestural musical interface similar to a laser harp.  The device uses reflective laser light to send control messages that can be used to control sound and live video. Control messages can be created by breaking the laser light with the hand (on/off), or by moving the hand up and down within the laser light (continuous), which is reflected back onto a photocell housed directly underneath the laser module. The photocell responds to the fluctuation in (or lack of) reflected light which causes an increase or decrease in resistance within the circuit, allowing for the changes in voltage to be registered by a micro-controller (CUI, Arduino). The MLGI has been used to control software instruments, musical robotics, live sound processing, effects, and live interactive video.  Due to the modular nature of it’s design, the MLGI can be re-configured in a number of ways.  In 2009, I was commissioned by David Rosenboom to build two custom MGLI devices for his interactive multimedia opera “Ah!”  The first design was a 10 laser system customized to fit the top of a Steinway grand piano.  The device was used to control samples and to mangle audio from the piano in real-time.  The second device was designed as a 12 laser Tetrahedron that was hung from the grid at REDCAT Theatre in LA.  The MLGI Tetra was used in an interactive dance piece where the dancer’s movement altered incoming audio and placed the sound spatially based on the performer’s location to the interface.
