Summary
This lecture presents the 30-year history of audio coding technology. Focusing on MPEG Audio Coding that
is the most widely used international standard in our daily life, some important techniques we contributed
are explained along the history. Recent standardization activities are briefly touched to show the unlimited
potential of audio coding. An encounter of the Silicon Audio, developed in 1994 and the real ancestor of iPod,
is the highlight of this lecture, which cannot be experienced elsewhere. The audience will see how iPod
started its function 20 years ago.
Short Biography
Akihiko Sugiyama (a.k.a. Ken Sugiyama), affiliated with NEC Information and Media Processing Labs., has
been engaged in a wide variety of research projects in signal processing such as audio coding and
interference/noise control. His team developed the world's first Silicon Audio in 1994, the ancestor of iPod. He
served as Chair of Audio and Acoustic Signal Processing Tech. Committee, IEEE Signal Processing Society (SPS)
[2011-2012], as associate editors for several journals such as IEEE Trans. SP [1994-1996], as the Secretary and a
Member at Large to the Conference Board of SPS, and as the Chair of Japan Chapter of SPS [2010-2011]. He is
a Technical Program Chair for ICASSP2012. He has contributed to 15 chapters of books and is the inventor of
over 150 registered patents with more pending applications in the field of signal processing in Japan and
overseas. He received 13 awards such as the 2002 IEICE Best Paper Award, the 2006 IEICE Achievement Award,
and the 2013 Ichimura Industry Award. He is Fellow of IEEE and IEICE, and a Distinguished Lecturer for IEEE
SPS. He is also known as a big host for a total of over 70 internship students.
