Washington - Feb 23, 2010 - Dr. Barry Blesser, digital audio pioneer and director of engineering for 25-Seven Systems will deliver the opening keynote speech at the 2010 NAB Show Broadcast Engineering Conference on April 11 at 9 a.m. Blesser, who has served as a technical and management consultant for the past 40 years to more than 50 high-tech companies, will provide insight on the broadcast engineering profession and its next generation of leaders.

As a former professor at the Massachusetts Institute of Technology and a founder of digital audio, Blesser has spent his four-decade career working at the junction of audio, acoustics, perception and cognitive psychology. From the start of his academic career at MIT in 1969, Blesser was a leading pioneer of digitized audio. He developed the first commercial digital reverberation system for the German company Elektro-Mess-Technik (EMT), helped found Lexicon and has developed audio products for Orban and many others.

Blesser is one of the founders and currently serves as director of engineering at 25-Seven Systems. He is the co-author of the recent book Spaces Speak, Are you Listening? Experiencing Aural Architecture, which examines auditory spatial awareness as an interdisciplinary exploration of architecture, music, acoustics, evolution, anthropology, cognitive psychology and audio engineering.
