Project

Larsen

This audio feedback system is a prototype designed to digitally manage or 'shape' resultant audio feedback tones as they resonate through an open cylinder waveguide. Pressure waves are produced in the air by a loudspeaker, guided through a configuration of pipes, and sensed by a microphone on the other end. By completing the partially open waveguide loop, energy is allowed to flow seamlessly between the external sound environment and the digital environment.

Anthony Paul De Ritis: Electroacoustic Music, in memorium: David Wessel

Albany Records has released a new CD by composer Anthony Paul De Ritis: Electroacoustic Music, In memorium: David Wessel

Composer Anthony Paul De Ritis began studying with David Wessel at the Center for New Music and Audio Technologies after returning from his studies at the American Conservatory in Fontainebleau. Wessel exerted a tremendous influence on De Ritis, both as a teacher and as a person. This recording of De Ritis' music is a tribute to David Wessel.

Jean Bresson: Interactive visual programming systems for music composition

Jean Bresson (IRCAM) was in residence at CNMAT as a Fulbright visiting scholar from Feb. to Aug., 2016, carrying out a research fellowship entitled "Interactive visual programming systems for music composition". The objectives of this project, framed in the development of computer-aided composition software, were to explore multimedia interactions in compositional processes, and integrate CNMAT technology and approaches in the OpenMusic environment.

Standing Wave Analog Feedback Device

As a continuation of previous audio feedback and instrumental prototyping projects, this analog audio feedback system generates a Helmholtz-like standing wave inside a resonant semi-sphere. The electronic configuration is based on a generic bullhorn circuit (with an electret mic and two 4ohm transducers) and is filtered through a passive RC low-pass filter. Few components are required and the circuitry can be easily embedded into a variety of hardware interface designs.

Project

Tana String Quartet

CNMAT welcomes the Tana String Quartet as an ensemble in residence for November, 2018. Public events include a concert at CNMAT on November 11th featuring new works by UC Berkeley graduate student composers and a concert at the Center for New Music in San Francisco on November 13th featuring works from the group's repertoire.

Project

Alice Unchained

Alice Unchained is a virtual chamber for chamber music. It is the third work loosely inspired by Alice in Wonderland, created by media artist Claudia Hart and composer Edmund Campion, Director, at the Center for New Music and Audio Technology, UC Berkeley. Alice mashes 3D animation, motion-captured live performance, and music performed by live and virtual musicians whose sound is analyzed in real-time and remixed in the bodies of sculptural avatars. It feeds-back the virtual and the live, blending them together in a liminal, uncanny mix.

Project

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

SHAPE

Sound and Habitat Audio Prototyping Environment (SHAPE) is a collection of nature-inspired electroacoustic devices created for sound art in public spaces. It is part of an ongoing audio feedback research project at the Center For New Music and Audio Technologies. By repurposing old electronics and manufactured objects, low-cost materials are used to make interactive sound sculptures and musical instruments. Subtle gestures and actions by participants change the sound in real-time.

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.

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

Tone

Tone is an analog audio feedback circuit with a tree-like array of three electret condenser microphones, a resonant loudspeaker, 9V amplifier, and a waveguide. This circuit is configured with the loudspeaker pointed upward at the mic array which produces audio feedback. The pipe configuration is situated above the loudspeaker/resonant chamber. The loudspeaker consists of a single 4Ω coil and raised glass sphere. When a participant walks around the device a Helmholtz-like standing wave is disrupted and produces different frequencies as a result.
