Karlheinz Brandenburg
was born in Erlangen, Germany in 1954. He received M.S. (Diplom) degrees
in Electrical Engineering in 1980 and in Mathematics in 1982 from Erlangen
University. In 1989 he earned his Ph.D. in Electrical Engineering, also
from Erlangen University, for work on digital audio coding and perceptual
measurement techniques. The techniques described in his thesis form
the basis for MPEG-1/2 Audio Layer-3, MPEG-2 Advanced Audio Coding (AAC)
and most other modern audio compression schemes. From 1989 to 1990 he
was with AT&T Bell Laboratories in Murray Hill, NJ, USA. He worked
on the ASPEC perceptual coding technique and on the definition of the
ISO/IEC MPEG/Audio Layer-3 system. In 1990 he returned to Erlangen University
to continue the research on audio coding and to teach a course on digital
audio technology. Since 1993 he is department head at the Fraunhofer
Institute für Integrierte Schaltungen (Fraunhofer IIS-A) in Erlangen,
Germany. He has presented numerous papers at AES conventions and IEEE
conferences. Together with Mark Kahrs, he edited the book "Applications
of Digital Signal Processing to Audio and Acoustics". In 1994 he
received the AES Fellowship Award for his work on perceptual audio coding
and psychoacoustics. In 1998 he received the AES silver medal award
for "sustained innovation and leadership in the development of
the art and science of perceptual encoding". Dr. Brandenburg is
a member of the technical committee on Audio and Electroacoustics of
the IEEE Signal Processing Society. He has worked within the MPEG-Audio
committee since its beginnings in 1988. He served as editor of MPEG-1
Audio, MPEG-2 Audio and as adhoc chair for a number of adhoc groups
during the development of MPEG-2 Advanced Audio Coding and MPEG-4 Audio.
From 1995 on, under his direction Fraunhofer IIS-A developed copyright
protection technology including secure envelope techniques (MMP, Multimedia
Protection Protocol) and watermarking. Dr. Brandenburg has been granted
24 patents and has several more pending.

Akihiko Sugiyama
received the B. Eng., M. Eng., and Dr. Eng. degrees in electrical engineering
from Tokyo Metropolitan University, Tokyo, Japan, in 1979, 1981, and
1998, respectively. He joined NEC Corporation, Kawasaki, Japan, in 1981
and has been engaged in research on signal processor applications to
transmission terminals, subscriber loop transmission systems, adaptive
filter applications, and high-fidelity audio coding. In the 1987 academic
year, he was on leave at the Faculty of Engineering and Computer Science,
Concordia University, Montreal, P.Q., Canada, as a Visiting Scientist.
From 1989 to 1994, he was involved in the activities of the Audio Subgroup,
ISO/IEC JTC1/SC29/WG11 (known as MPEG/Audio) for international standardization
of high-quality audio data compression as a member of the Japanese delegation.
His current interests lie in the area of signal processing and circuit
theory. Dr. Sugiyama is a member of the Institute of Electrical and
Electronic Engineers (IEEE) and the Institute of Electronics, Information
and Communication Engineers (IEICE) of Japan. He served as an associate
editor for the IEEE T RANSACTIONS ON S IGNAL P ROCESSING from 1994 to
1996. He is also a member of the Technical Committee for Audio and Electroacoustics,
IEEE Signal Processing Society. He is currently serving as an associate
editor for the Transactions of the IEICE on Fundamentals of Electronics,
Communications and Computer Sciences. He received the 1988 Shinohara
Memorial Academic Encouragement Award from IEICE. He is a coauthor of
International Standards for Multimedia Coding (Yokohama, Japan: Maruzen,
1991), MPEG/International Standards for Multimedia Coding (Tokyo, Japan:
Ohmusha, 1996), Digital Broadcasting (Tokyo, Japan: Ohmusha, 1996),
and Digital Signal Processing for Multimedia Systems (New York: Marcel
Dekker, Inc., 1999). Dr. Sugiyama is the inventer of 50 registered patents
in the US, Japan, Canada, Australia, and European Patent Committee (EPC),
in the field of signal processing and communications.

was born in 1968 in Hagen, Germany. He received his M.S. (Diplom) from
Bochum University in 1995. His master thesis at the chair of Prof. Blauert
was on a realtime model of binaural localisation of sound sources. He
joined the department Audio/Multimedia at the Fraunhofer Institut für
Integrierte Schaltungen (Fraunhofer IIS-A) in 1995. He worked on the
implementation and optimisation of a high-quality realtime MPEG Layer-3
encoder for the digital radio system WorldSpace and actively contributed
to the standardisation of MPEG-2 AAC. Since January 1998 he is head
of the Audio Coding group at FhG-IIS. Responsibilities of this group
range from quality optimisation of state-of-the-art coding schemes and
contributions to international standardisation bodies to audio broadcast
system related issues.
