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. 
  
  2. Multiple channels (e.g., 4 to 48 and beyond, depending 
  on the application)
    3. 
  
  3. CD quality resolution or better
    4. 
  
  4. Very near real-time bidirectional throughput for 
  interactive applications
    5. 




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.
