He is probably best known for what is now called the Baxandall tone control circuit, first published in a paper in Wireless World. 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 Baxandall"s bass and treble circuit, when made public in Wireless World (1952), "swept all others before it".
The design is now employed in millions of hi-fi systems (Baxandall received no royalties for his work). lieutenant exists in two versions—Baxandall"s original had two capacitors, but the more popular, simplified version only has one.
lieutenant finds an application in hi-fi audio equipment and in amplifiers and effects for musical instruments.
