AES Paris 2016 Presenter or Author
Louis Fielder
Primary Affiliation: Dolby - San Francisco, CA, USA
AES Member Type: Life Fellow
Louis Fielder received a BS. degree in electrical engineering from the California Institute of Technology in 1974 and an MS. degree in acoustics from the University of California in Los Angeles in 1976.
During the period between 1976 – 1978 he worked on electronic component design for custom sound reinforcement systems at Paul Veneklasen and Associates. From 1978 – 1984 he was involved in digital-audio and magnetic recording research at the Ampex Corporation. At that time he became interested in applying psychoacoustics to the design and analysis of digital-audio conversion systems. Since 1984 he has worked at Dolby Laboratories on the application of psychoacoustics to the development of audio systems and on the development of a number of bit-rate reduction audio coders for music distribution, transmission, and storage applications, i.e. AC-1, AC-2, AC-3, Enhanced AC-3, AAC, and Dolby E. Additionally, he has investigated perceptually derived limits for the performance for digital-audio conversion, low-frequency loudspeaker systems, distortion limits for loudspeakers/headphones, loudspeaker-room equalization, and headphone virtualization. He managed the Sound Technology Research Department at Dolby Laboratories in San Francisco from 2005 - 2009. Currently, he is a principal member of the technical staff working on headphone virtualization and perceptual metrics for loudspeaker distortion.
Louis Fielder is a fellow of the AES, a senior member of the IEEE, a member of the SMPTE, and a member of the Acoustical Society of America. He was on the AES Board of Governors during 1990 –1992, President during 1994 – 1995, and Treasurer 2005 - 2009.
