The CCRMA Hearing Seminar returns next week with a discussion of
Computational Auditory Scene Analysis.  Auditory Scene Analysis was the
title of a book by Al Bregman talking about how we perceive our auditory
environment by grouping sounds into objects.

Computational Auditory Scene Analysis, or CASA for short, is the process of
building computer programs to simulate the auditory scene analysis process.
Last August there was a workshop on this topic and I'll be reviewing the
results, discussion, and problems that were talked about at the workshop.

        Who:    Malcolm Slaney (Interval)
        What:   Review of Computational Auditory Scene Analysis Workshop
        When:   Thursday, October 12th at 11AM
        Where:  CCRMA Library (Top Floor of the Knoll at Stanford)

In an hour or so, the presentation can only be an overview of the work that
I found interesting.  There were many talks, some physiologically based,
some based on engineering solutions.  All were addressed at attempts to
understand the acoustic input signal.

As a special treat, I do hope to have a video tape showing Masataka Goto's
real-time beat tracking system.  (There is even an animation dancing to an
acoustic input signal.)  See
        http://www.info.waseda.ac.jp/muraoka/members/goto/PROJ/bts.html
for more information.  It's pretty cool.

A written description of the CASA workshop can be found at

Or drop me a note, and I'll email you a copy.

Parts of the CASA workshop have already been Hearing-Seminar presentations,
or will be a separate meeting.  The discussion we had on the paper "A
Critique of Pure Vision" and my extensions to audition were the basis of
one of the CASA workshop's discussion periods.  Work by Rolf Worhmann, now
a CCRMA Visiting Scholar, on wavelet models of perception will be described
by him on October 26.

See you at CCRMA.
