Biography

Baxandall attended

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.[1]

Baxandall tone control circuit

Baxandall's bass and treble control circuit, when made public in Wireless World (1952), "swept all others before it".[2] An early version of the design had already won him an award in 1950 (a $25 watch) at the British Sound Recording Association, a predecessor of the Audio Engineering Society. The design is now employed in millions of hi-fi systems (Baxandall received no royalties for his work).[1]

It exists in several versions—Baxandall's original had two capacitors per potentiometer, but it is possible to use only one at either the treble or bass potentiometers, or both.[2] It finds an application in hi-fi audio equipment and in amplifiers and effects for musical instruments, erroneously shown in [3] and cited in.[4]
