May Meeting Notice

 

May 2003 Meeting Notice


 Subject: Audio Over Next-Generation Internet
 Speakers: Chris Chafe, Scott Wilson, Dan Walling
 Place: CCRMA, Stanford University, The Knoll Building
 Time and Date: May 20th, 7:30 PM (refreshments at 7:00 PM)

Low-latency, high-quality audio transmission over next-generation Internet is a reality. Bidirectional, multichannel flows over continental distances have been demonstrated in musical jam sessions and other experimental situations. The dominating factors affecting delay are no longer system issues, but the transmission time bounded by lightspeed.

In order for these resources to be useful in the domain of professional audio, systems must be able to deliver signals according a stringent set of requirements:

  1. Uncompressed linear sampling (or at least fast, lossless signal compression if compression is necessary)
  2. Multiple channels (e.g., 4 to 48 and beyond, depending on the application)
  3. CD quality resolution or better
  4. Very near real-time bidirectional throughput for interactive applications

The SoundWIRE (Sound Waves on the Internet from Real-time Echoes) group at CCRMA will demonstrate a prototype system and discuss its technical features.

Chris Chafe (Professor of Music) is director of the Stanford Center for Computer Research in Music and Acoustics (CCRMA). His research areas range from composition and performance, to computer networks for audio and musical signal analysis/synthesis. He has articles published in various technical journals including Computer Music Journal, Proceedings of ICMC, and IEEE conferences.

Scott Wilson is a PhD candidate at CCRMA. He received his Bachelor's degree in music from McGill University in Canada and studied recording at the Banff Centre for the Arts in Alberta, Canada. Research interests include interactive audio, machine learning and human computer interaction for music. He is Vice-President of the Stanford AES chapter.

Daniel Walling in an undergraduate at Stanford majoring in Music, Science and Technology.

From 101 - Exit at Embarcadero Road heading west. As Embarcadero crosses El Camino Real it becomes Galvez Street. On Galvez, turn left at the first stop sign, onto Campus Drive. Follow Campus Drive to Mayfield Avenue; turn right on Mayfield (and follow it as it curves left). At the end of Mayfield turn left on Lomita Drive. The Knoll is at 660 Lomita.

From 280 - Exit at Alpine Road heading east. At the first traffic light, turn right onto Junipero Serra Boulevard. At the next traffic light, turn left onto Campus Drive West. At the stop sign, turn right onto Santa Teresa. Continue on Santa Teresa until the second stop sign, then turn right on Lomita Drive. Stay to the right on Lomita; the Knoll is at 660 Lomita.
