Baxandall attended King's College School in London, then got his BSc in electrical engineering at Cardiff Technical College (1942). He was a radio instructor for the Fleet Air Arm for two years, and then worked for the Telecommunications Research Establishment (at the Circuit Research Division headed by Frederic Calland Williams), later renamed and merged to form the Royal Signals and Radar Establishment, until his retirement in 1971. After retiring he worked as a consultant on various audio projects including loudspeakers, tape duplication, and microphone calibration. During this time he continued to publish, including a "seminal chapter" on electrostatic loudspeakers. The Audio Engineering Society made him a Fellow in 1980, and in 1993 awarded him with a Silver Medal for his contributions to the field.
