Principal Member Technical Staff - Dolby Australia
David McGrath is a graduate with a B.Sc. and B.E. (Elec) from the University of Sydney and began his professional career as an Integrated Circuit designed with Austek Microsystems in Adelaide. Austek had been spun off from the CSIRO a year or two earlier, and the close ties with CSIRO – particularly the Division of Radiophysics – led to the co-development of a number of signal-processing ICs.
David joined CSIRO in Sydney in 1990, and in 1991, with the assistance and encouragement of CSIRO, he co-founded an audio signal-processing start-up, Lake Technology. Lake went on to develop audio processing hardware that was used by many of the world’s leading acoustics researchers at organisations that included Bell Labs, British Telecom, Panasonic, Motorola, BMW and Ferrari.
In 1998, Lake completed the development of its first consumer-facing audio technology, and this led to a technology licensing agreement with Dolby Laboratories. The relationship with Dolby grew over the following years, and in 2005 Lake was acquired by Dolby. David now works in Dolby’s Sydney office, within Dolby’s Sound Technology Research Team. His current work is particularly focussed on human perception of spatial sound, and the associated signal processing that is used to analyse and process spatial sound.
