 Although Ambisonics was not a commercial success, its theory underpinned much of his later work in audio such as his work with Waves Audio and Trifield.He was also active in the development of digital sound techniques, such as noise-shaped dither and Meridian Lossless Packing (MLP, the lossless compression used in DVD-Audio disks).The Audio Engineering Society recognised Gerzon's work in audio by awarding him a fellowship in 1978 and the AES Gold Medal in 1991.
