BIO:
James D. Johnston (F) received his BSEE and MSEE from Carnegie-Mellon University.
Dr. Johnston joined DTS Inc., from his position at Neural Audio. Prior to that, he worked for 5 years at Microsoft Corporation in the "Codecs", "Core Media Processing" and finally the video services groups as Audio Architect.
Dr. Johnston retired from AT&T Labs - Research, quartered at Florham Park, NJ, Speech Processing Software and Technology Research Department. Before that, he was employed by AT&T Bell Laboratories, in the Acoustics Research Department under Dr. J. L. Flanagan, and in the Signal Processing Research Department.
Dr. Johnston was the primary researcher and inventor of the MPEG-2 AAC audio coding algorithm, and a principle contributor to the "MP3" algorithm. He also represented AT&T in the ANSI accredited group X3L3.1, and X3L3.1 in the ISO-MPEG-AUDIO (MP3, AAC) arena. Dr. Johnston was awarded the IEEE James L. Flanagan Signal Processing Field Award (2006); elected Fellow, Audio Engineering Society (1997); received AT&T Technology Medal and AT&T Standards Award (1998); received a New Jersey Inventor of the Year Award (2001); elected IEEE Fellow (2002).
Dr. Johnstonas current research interests include acoustic scene modelling, loudspeaker design, loudspeaker pattern control, cochlear modelling, masking threshold models, stereo imaging models and stereo imaging sensitivity models, methods of reproducing soundfields either literally or perceptually, microphone and soundfield capture techniques, both actively steered and time-invariant, and speech and audio coding methods in general.
