This is the personal website of John Usher.

 

John Usher was born and bred in Devon, England.

He holds a B.Eng. degree in Electro-Acoustics from the University of Salford and in 2006 received his Ph.D. from McGill University, where he was supervised by Dr. W.L. Martens; Prof. W. Woszczyk; Dr. J. Benesty and Prof. A. Bregman.

His Ph.D. thesis was on the theoretical development and subjective evaluation of a new ambiance extraction upmixer: the system he designed allows you to play stereo audio on a “surround sound” loudspeaker system.

John’s upmixer algorithm was further developed for multichannel cinema audio and is now part of Dolby Atmos (patent #8,335,330).

He has conducted research at the acoustics department of Bang and Olufsen, the DSP group at Philips Nat Lab, and has undertaken research residencies at the Banff Centre.

Since 2006 he has been chief system architect at Personics Labs (AKA Hearium), where he has over 30 issued patents on audio signal processing relating to a new earphone for augmented reality, music listening and voice communications.

John has little experience talking about himself in the third person, and generally treads a path outside of this solipsistic realm into matters of new loudspeaker technology.
