Developing Commercially Viable Audio Coding Algorithms

Yu-Li You, Ph.D.

Audio coding algorithms are used to obtain compact representations of
high quality audio signals for efficient transmission or storage. A
variety of issues need to be carefully considered and tackled when
developing a commercially viable algorithm, including the trade-off
between coding efficiency and decoder complexity. This presentation
will discuss the fundamental properties of audio signals and make a
special note that the human ear processes audio signals primarily in
the frequency domain. It will then describe a general structure for
audio coding algorithms and discuss how it was embodied in a few audio
coding standards, including China’s DRA Multichannel Digital Audio
Coding Algorithm.

Yu-Li You received his Ph.D. in 1995 from the University of Minnesota
in Twin Cities and MS and BS degrees from Northwestern
Telecommunication Institute, Xian, China, in 1988 and 1985,
respectively. He worked for Seagate Technology from 1995 to 1996 and
DTS from 1996 to 2001. He co-founded Audioplus Technology in 2001 and
served as its CTO and Vice President. He co-founded Digital Rise
Technology in 2004 and has served as its CTO and Vice President since
then. He is an adjunct associate professor since 2008 and was an
adjunct assistant professor from 1997 to 1998, both for the University
of Minnesota in Twin Cities.

Yu-Li is the inventor and author for China’s DRA Multichannel Digital
Audio Coding Standard, which is labeled as the first autonomous
Chinese standard accepted by an international organization (Blu-ray
Disc Association). He published more than 20 journal and conference
papers and has more than 30 issued or pending patents.
