John Chowning

John M. Chowning (; born August 22, 1934, in Salem, New Jersey) is an American composer, musician, discoverer, and professor best known for his work at Stanford University, the founding of CCRMA – Center for Computer Research in Music and Acoustics in 1975 and his development of the digital implementation of FM synthesis and the digital sound spatialization while there. Contribution Chowning is known for having developed the FM synthesis algorithm in 1967. In FM (frequency modulation) synthesis, both the carrier frequency and the modulation frequency are within the audio band. In essence, the amplitude and frequency of one waveform modulates the frequency of another waveform producing a resultant waveform that can be periodic or non-periodic depending upon the ratio of the two frequencies. Chowning’s breakthrough allowed for simple—in terms of process—yet rich sounding timbres, which synthesized ‘metal striking’ or ‘bell like’ sounds, and which seemed incredibly similar to real percussion (Chowning was also a skilled percussionist). He spent six years turning his breakthrough into a system of musical importance and eventually was able to simulate a large number of musical sounds, i
