frequency modulation synthesis
Quick Summary
Frequency modulation (FM) synthesis is a technique used in music synthesizers to create and modify sounds. It involves altering the frequency of a carrier wave based on the characteristics of a signal. This process allows for the generation of a wide range of complex and unique timbres beyond those of traditional instruments.123
In FM synthesis, one waveform (the modulator) is used to alter the frequency of another waveform (the carrier). By manipulating the frequencies and amplitudes of these waves, musicians can produce diverse sonic textures. This method became prominent in the late 1970s and 1980s with the development of more compact digital synthesizers.3
