A E R

A E R is a site-specific installation, by UC Berkeley Graduate Composer Didem Coskunseven and Engin Daglik (Stanford), focusing on turning a ‘transitive space’ into a ‘space of experience’ by using lighting design and interactive spatial sound design in such a way that they manifest both an uncanny and inviting ambience. The work consists of four light structures hung on the surfaces of a shipping container and 8-channel interactive audio immersed in this transitive space.

Tone

Tone is an analog audio feedback circuit with a tree-like array of three electret condenser microphones, resonant 4Ω loudspeaker, 9V amplifier, and cylindrical waveguide. Acrylic 'leaf' microphone mounts are suspended at the end of each cylindrical 'branch.' Acoustic feedback is situated by arranging the loudspeaker upward toward the mic array. As pressure waves propagate upward from the loudspeaker, sound is filtered through the pipes before arriving at the mic array, thus introducing non-linearities in the system.

Project

Magnetic Resonator Piano

In Spring 2019 Jeremy Wagner set out to build a piano resonating device for upcoming research projects and performances by CNMAT composers.  This work draws heavily on prior design work by Per Bloland, et al. with some improvements specific to upcoming CNMAT projects.  The design brief called for a device meeting the following criteria:

Project

Bloom

Bloom is a flower-like analog oscillator on a transparent substrate comprised of three piezoelectric transducers, one transistor, one 3V battery, three LEDs, three photoresistors, and three resistors. This circuit is configured in a feedback loop which allows it to self-oscillate and produce variable light/sound sequences. The transparent substrate and stem-like conductive trace design gives each component an aesthetic quality. Photoresistors on the piezo elements provide subtle interaction by changing the electrical resistance when light is more or less present.

CNMAT Multi-Purpose Array

In the Summer of 2018 CNMAT was awarded a grant to construct infrastructure for producing mobile, multi-channel concert events.  We set out to construct a surround audio system, designed with robust mobility in mind, that can be rapidly deployed in numerous performance contexts.  The result is the CNMAT Mobile Array, an expandable mobile infrastructure for sonic events.  The system is conceived to be deployed in under an hour by a small crew of one or two people.  Its speaker elements are weather protected to enable work outdoors and we have included a number of flexible rigging options to
