                  Signal Adaptive Subband Audio Coding

                              John Princen
                            Silicon Graphics

      Date: May 5, 1995   Time: 2:30-3:30   Room: 405 Soda Hall
                  (presentation starts at 2:30 sharp)

The application of subband coding to high quality audio compression has
lead to a significant reduction in the bitrate necessary to provide CD
quality audio. The success of subband coding has resulted from the
application of psycho-acoustic principles and new filterbank designs.
Despite this success there is still room for improvement. In this talk I
will introduce the ideas from psycho-acoustics which are important in
audio compression and discuss the design of optimal filterbanks. Within
this framework I will comment on the current crop of high quality coding
systems (such as MPEG audio). As the title suggests good filterbank
designs for audio coding should be signal adaptive (ie time varying)
and I will present a coding system which demonstrates some aspects of
optimal filterbank design.

This seminar will be broadcast on the MBONE starting at 2:30.  The seminar
will start promptly at 2:30. 405 Soda Hall is a relatively small seminar 
room (approx. 25 seats).  Folks at Berkeley might want to attend the 
seminar by watching it on your workstation, if it can receive MBONE 
transmissions.  For further information on accessing the MBONE contact 
see the FAQ (/usr/sww/doc/faq/mbone.faq).  You can also look at the 
information accessible from http://roger-rabbit.cs.berkeley.edu/298.html.
