Perceptual Audio Coding – An Overview of Basic Principles and Current Standards
Who would have guessed twenty years ago that teenagers and everybody else would be clamoring for devices with MP3/AAC (MPEG Layer III/MPEG Advanced Audio Coding) perceptual audio coders that fit into their pockets? As perceptual audio coders become more and more part of our daily lives, residing within mobile devices, DVDs, broad/webcasting, electronic distribution of music, etc., a natural question to ask is: what made this possible and where is this going? This talk, presented by one of the early developers who helped advance the field of perceptual audio coding, will provide a tutorial on the technology employed in perceptual audio coding and a brief overview of past and current standard development.
Marina Bosi has been actively involved for many years in the development of standards for audio coding, video coding, and digital content management, having contributed to the work of ANSI, ATSC, DVD Forum, DVB, ISO/IEC MPEG, SDMI, and SMPTE. Dr. Bosi holds several patents and publications in the field and is author of the acclaimed textbook “Introduction to Digital Audio Coding and Standards” (Kluwer/Springer December 2002) translated into Chinese and Korean.
Dr. Bosi, a past-President of the Audio Engineering Society (AES), was part of the research team at Dolby Laboratories working on AC-2 and AC-3 ( Dolby Digital) technology where she also led the MPEG-2 AAC development, and she was Chief Technology Officer of MPEG LA, an industry leader in the use of patent pools to create a “one-stop shop” for licensing essential patents required of multimedia technologies.
A senior member of IEEE, her recognitions include the AES Fellowship award for her contributions to audio and video standards development, twice the AES Board of Governors award for chairing the first international conference on high quality audio coding and the AES Convention, the ISO/IEC award for being the Editor of ISO/IEC 13818-7, Advanced Audio Coding.
Dr. Bosi is Consulting Professor in the Music Department at Stanford University and a Founding Director (together with Leonardo Chiariglione, MPEG Chair) of the Digital Media Project, a non-profit organization that promotes successful development, deployment, and use of Digital Media. She received a doctorate in Physics from the University of Florence, Italy.
FROM POINTS NORTH AND SOUTH: Take Interstate 95 (Route 128) to Exit 24 (Route 30). Proceed east on Route 30, also known as Commonwealth Avenue, and follow for about five miles to Boston College.
FROM POINTS WEST: Take the Massachusetts Turnpike (Route 90) to Exit 17. At the first set of lights after the exit ramp, take a right onto Centre Street. Follow Centre Street to the fourth set of lights, and turn left onto Commonwealth Avenue. Follow Commonwealth Avenue 1-1/2 miles to Boston College.
FROM DOWNTOWN BOSTON: Take the Massachusetts Turnpike (Route 90) to Exit 17. Take a left over the bridge after passing the Sheraton Tara Hotel. Take the first right onto Centre Street. Follow above directions from Centre Street.
PUBLIC TRANSPORTATION: The Boston College branch of the MBTA’s “Green Line” (B) ends at the Boston-Newton boundary on Commonwealth Avenue
Devlin Hall is located in the center of the Chestnut Hill Campus. Parking is available in the Commonwealth Ave Garage for a minimal price. The entrance for Room 026 is in the rear of Devlin hall. Parking on Commonwealth Ave is also FREE!
