Tapping into the Internet as a Musical / Acoustical Medium


Chris Chafe


CCRMA, Stanford University

Time and Date:

April 27, 2010  7:30 PM (refreshments at 7:00 PM)


Recent work in Internet audio is making distance music ensembles a reality and creating sound spaces for musical exploration. Still in its earliest stage but interesting to imagine, is the possibility of an entirely new acoustical medium resulting from lacing the globe with real-time audio.

The presentation includes three subtopics:
1) remote musical collaboration using professional-quality, low-latency audio
2) sounds from "plucking" the network, in which internet acoustics mimic a guitar string and let you directly hear a network's quality-of-service
3) a study of temporal separation (network delay) as it affects ensemble rhythm

And two demos:
-- live demo of synchronized jamming across the Bay Area with MusicianLink's jamLink devices presented by Dave Willyard (MusicianLink)
-- live demo of multichannel transport with CCRMA using open-source application, jackTrip, to connect spaces with a variety of mic arrays presented by Fernando Lopez-Lezcano (CCRMA)

About the Speakers

Chris Chafe is a composer, improvisor, cellist, and music researcher with an interest in computer music composition and interactive performance. He has been a long-term denizen of the Center for Computer Research in Music and Acoustics where he directs the center and teaches computer music courses. Three earlier year-long research periods were spent at IRCAM, Paris, and The Banff Center, composing and developing methods for computer sound synthesis. His SoundWIRE project is developing tools for real-time musical collaboration over the Internet. An active performer, he has performed in Europe, the Americas and Asia. Discs of his works are available from Centaur Records. Continuing into a second decade of gallery and museum music installations, biological and environmental content is being featured. Improvisantional contexts have recently included performances with Roberto Morales, Simon Rose, Pauline Oliveros, Roscoe Mitchell, Mark Dresser, Dave Douglas, and the five countries "Resonations" concert, among others.

Fernando Lopez-Lezcano is a composer, performer, lecturer and computer systems administrator at CCRMA, Stanford University. He has been teaching and taking care of computing resources there since 1993, and created and maintains since 2001 the Planet CCRMA collection of open source sound and music packages for Linux. He has been involved in the field of electronic music since 1976 as a composer, performer and instrument builder, blurring the lines of his dual background in music (piano and composition) and electronic engineering. Recently he was the "Edgar Varese Guest Professor" at TU Berlin during the Summer 2008 semester.
