WORKSHOP SESSIONS
W1:ALTERNATIVE TRANSDUCTION TECHNIQUES;
BEYOND MOVING COIL DIRECT RADIATION
Saturday, 19 February, 10:00 h � 12:00 h
What advantage can be gained from looking beyond the
paradigm of axial pistonic sound reproduction? An eclectic
collection of manufacturers and experimenters demonstrate
transducers that reproduce sound without axial pistonic
motion. A listening experience and a brief tutorial explaining
the technologies are provided. This workshop offers a unique
opportunity to compare these transducers first hand.
W2:ACOUSTIC TREATMENT OF ASYMMETRICAL
PLAYBACK ENVIRONMENTS
Saturday, 19 February, 10:00 h � 12: 00 h
Environmental circumstances and the desired function of
music studio control rooms may not always allow a strict
symmetrical acoustic treatment about a central axis, while
common sense would require such geometry. Many engineers
and music composers have little choice but to make use of
ever smaller spaces to do their work, and are forced to treat
these spaces with the minimum loss of actual usable volume
and floor space. What are some of the solutions proposed to
treat such axially challenging spaces? What constitutes an
impossible situation?
W3:MPEG-4 VERSION 2 AUDIO � WHAT IS IT ABOUT?
Saturday, 19 February, 14:00 h � 16:30 h
MPEG-4 is the most recent member of the well-known family
of ISO/MPEG coding standards, and provides an integrated
set of audio coders with attractive capabilities, including
bit-rate and bandwidth scalability. After the release of the
MPEG-4 standard in 1999, the new Version 2 Standards
Addendum, to be published in 2000, defines extended
functionalities, such as low delay audio coding, parametric
audio coding, error resilience and spatialization. The
workshop aims at answering the questions "what is MPEG-4
v2 and what can I do with it?" and includes a number of
demonstrations.
MEETING OF THE TECHNICAL COMMITTEE on Transmission and Broadcasting
16:30 - 18:00, following Workshop W3
W4:DESIGN AND MODELING OF LINEAR ARRAY
SOUND SYSTEMS
Saturday, 19 February, 14:00 h � 16:30 h
The recent renaissance of linear arrays for sound
reinforcement will be discussed, beginning with an historical
overview and followed by a description of the theoretical
principles and operating concepts behind a current example of
a line array system. Techniques for modeling linear arrays will
be discussed along with challenges involved in simulation and
measurement. It is hoped that a technical tour of an installation
at the Palais de Congr�s will provide a demonstration of
system performance and allow for the comparison of
simulated versus in-situ measurement results.
