Subject:

Research at CNMAT: New Computer-Based Musical Instruments, Many Channel Audio Systems, and Open Sound Control

Speakers:

David Wessel, Andy Schmeder and Adrian Freed

Place:

Center for New Music and Audio Technologies (CNMAT), UC Berkeley

Time and Date:

September 24th, 7:30 PM (refreshments at 7:00 PM)

Description:

CNMAT is focused on the development of new musical instruments and new modes of interacting with musical material. Gesture sensing plays an important role and our research effort involves the prototyping of new physical devices as well as circuitry for extracting musically useful control information from sensor data streams. We have pioneered the Open Sound Control (OSC) protocol for temporally precise messaging. For sound diffusion we have developed spherical speaker arrays that afford dynamic control of the radiation patterns.
We will provide a survey of recent audio and music technology research activities at CNMAT. These include innovative sensor technologies for new musical interfaces, speaker arrays with over 140 independent channels, and an update to the Open Sound Control specification (OSC 1.1).

About the Speakers:

David Wessel studied mathematics and experimental psychology at the University of Illinois and received a doctorate in mathematical psychology from Stanford in 1972. His work on the perception and compositional control of timbre in the early 70\'s at Michigan State University led to a musical research position at IRCAM in Paris in 1976. In 1985 he established a new IRCAM department devoted to the development of interactive musical software for personal computers. In 1988 he began his current position as Professor of Music at the University of California, Berkeley where he is Director of CNMAT. He is particularly interested in live-performance computer music where improvisation plays an essential role. He has collaborated in performance with a variety of improvising composers.

Adrian Freed\'s first publication in 1975 was a design for electronic doorbell with an unusually compact implementation. This wasn't a particularly powerful musical tool, but in those days access to computational machinery of any kind was exceedingly difficult and dedicated electronic circuits were the only route possible to hobbyists. While at the University of New South Wales he developed control software for a digital additive synthesizer, the groupatron, built into the chassis of a Fairlight synthesizer. In 1982 he was invited to IRCAM where he was director of computing systems and secretary of the Scientific Committee. He was early to recognize the importance of temporal constraints in music systems, a theme throughout his work at CNMAT. As leader of CNMAT\'s Guitar and chordophone Innovation Group (GIG), he has focused on hardware and signal processing software to take advantage of separate processing of each string. His lifelong efforts to improve the guitar are documented in sfweekly and he was invited to Paris in 2009 to a conference on the Future of the Electric Guitar.

Andy Schmeder received the B.A. in Mathematics from UC Berkeley in 2002, and has also studied topics in computer science, new media, music and statistics. He has worked in IT consulting for several years, and as a programmer at the Hafter Auditory Perception Lab. In Fall 2006 he joined the CNMAT team as full-time staff. Research areas include many-channel spherical speaker systems, microprocessor software for rapid prototyping of new interfaces with real-time performance, music quality issues for hearing-impaired listeners, representation issues in digital communication of musical gesture information.

Parking:

Parking is a challenge around CNMAT and in Berkeley in general. Much of the area close to CNMAT is a vigorously enforced 2 hour zone.

Public Parking

UC Berkeley North Gate Parking

The parking garage is on Hearst Avenue at the corner of Scenic Avenue and has four levels. The lowest level is accessible on Hearst Avenue and the top three levels are accessible around the corner on Scenic Avenue.
Monday through Friday from 5 p.m. to 2 a.m., Saturday from 7 a.m. to 2 a.m. and Sunday from 1 p.m. to 2 a.m. all four levels of the Hearst garage are open to public parking. Paid by the hour: starts at $1 for the first hour up to $7 for all day. Plenty of empty spaces should be available.
IMPORTANT: Monday through Friday from 7 a.m. to 5 p.m. only the second level of the Hearst garage is open to public parking. Paid by the hour: starts at $3 for the first hour up to $15 for all day.

Street parking

On city streets around Hearst and Euclid Avenues you can park for up to 2 hours during the day. Some slots simply restrict parking for between 30 minutes and 2 hours. Metered spaces similarly vary in time from 30 minutes to 2 hours.
Parking meters are enforced until about 6 or 7 p.m. Monday through Saturday.
