What's Inside
This Month's Meeting
Preview
The best of the papers and floor exhibits
from the 99th AES Convention...
John Vanderkooy and Stan Lipshitz are back again to give us their yearly review of the
papers
presented at the annual AES convention, this year held in New York. For those who
couldn't attend the
convention, this is an execellent opportunity to get an overview of the papers, presented
in an informative
and digestable format by John and Stan.
And as usual, our members have taken their cameras onto the Exhibits floor and will present
slides of
what's new and gee-whiz in the audio world.
WHO THE PRESENTERS ARE
John Vanderkooy
Audio Research Group, University of Waterloo
John Vanderkooy was born in The Netherlands in 1941, but received all of his education in
Canada, with
a B. Eng. degree in engineering physics in 1963 and Ph.D. in physics in 1967, both from
McMaster
University in Hamilton, Ontario. For some years he followed his doctoral interests
in low-
temperature physics of metals at the University of Waterloo, where he
is currently a professor
of physics. However, since the late 1970s, his research interests have been
mainly in audio and
electroacoustics.
A fellow of the AES and a member of the IEEE, Dr. Vanderkooy has contributed a
variety of papers at conventions and to the Journal. Together with his
colleague Stanley
Lipshitz and a number of graduate and undergraduate students, they form the
Audio Research
Group at the University of Waterloo.
Dr. Vanderkooy's current interests are digital audio signal processing, measurement
of transfer
functions with maximum-length sequences, transducers, diffraction of loudspeaker cabinet
edges, and
most recently sub-surface analysis techniques using maximum-length sequences.
Audio Research Group, University of Waterloo
Stanley P. Lipshitz is a professor in both the departments of Applied Mathematics and
Physics at the
University of Waterloo, Ontario, Canada. There, in addition to the normal teaching
associated with a
university position, he conducts his own and supervises graduate student research
in audio and
electroacoustics as a member of the university's Audio Research Group.
Prior to joining the faculty of the University of Waterloo in 1970, he studied
in South Africa, the
country of his birth, where he received his Bachelors (1964), Masters (1966) and Ph.D.
(1970) degrees in
applied mathematics. He is now a Canadian citizen.
He is a fellow of the Audio Engineering Society, and served as a governor for the
periods 1984-
1986, 1987-1992, and as its President for the year 1988-1989. He is a member of the
Review Board of the
Society's Journal, and serves on the Publications Policy Committee. Other society
memberships include
the IEEE, the Acoustical Society of America, and the Canadian Acoustical Association.
He is also Vice-
President and recording engineer of the Kitchener-Waterloo Chamber Music Society.
He has presented numerous technical papers at AES Conventions, both in North America
and
overseas, on a wide range of topics including amplifier design, psychoacoustics,
loudspeaker crossover
design, electroacoustic transducer measurement techniques, acoustics, and digital
signal processing for
audio.
He has participated in many educational workshops and seminars on audio topics including
loudspeaker measurement, stereo microphone techniques, and the fundamentals of digital audio.
His
publications have appeared frequently in the AES Journal and elsewhere.
His current research interests include transducer design and measurement, digital
signal
processing for audio including the mathematical theory of dithered quantizers and
noise shapers, the
calculation of acoustic diffraction, adaptive room deconvolution, and the characterization
and design of
surround-sound systems. He has consulted for a number of companies on audio-related
matters.
In October 1993, he received the AES Silver Medal Award for his research contributions
to
audio.
The new phone number is 416/480-0181.
This will allow more members access to the system without incurring a long
distance charge.
