Frequency modulation - Wikipedia

FM synthesis is very good at creating both harmonic and inharmonic ("clang", "twang" or "bong" noises) sounds. Complex (and proper) FM synthesis using analog is not generally feasible due to their inherent pitch instability, but FM synthesis (using the frequency stable phase modulation variant) is easy to implement digitally. As a result, FM synthesis was the basis of some of the early generations of from Yamaha, with Yamaha's flagship synthesizer being ubiquitous throughout the 1980s. Yamaha had patented its hardware implementation of FM, allowing it to nearly monopolize the market for that technology. developed a related form of synthesis called , used in its CZ series of synthesizers. It had a similar (but slightly differently derived) sound quality as the DX series.

If the amplitude of the modulator is 0, the output frequency of the carrier oscillator is simply Fc . Otherwise, the amplitude of the modulating signal causes the frequency of the carrier oscillator to swing above and below Fc . This frequency swing is known as "deviation".

For synthesizing harmonic sounds, the modulating signal must have a relationship to the original carrier signal. As the amount of frequency modulation increases, the sound grows progressively more complex. Through the use of modulators with frequencies that are non-integer multiples of the carrier signal (i.e., non harmonic), bell-like dissonant and percussive sounds can easily be created.

In simple terms, the "louder" the modulating signal is, the more the carrier frequency changes. For illustration, suppose Fc is 1000 Hz. Modulation amplitude might be applied that causes the carrier to swing between 900 Hz and 1100 Hz, that is, 100 Hz in either direction. This is termed a "deviation" of 100 Hz.

Sound Synthesis Theory/Modulation Synthesis - …

In and frequency modulation synthesis (or FM synthesis) is a form of where the of a simple waveform is changed by it with a modulating frequency that is also in the audio range, resulting in a more complex waveform and a different-sounding tone. The frequency of an oscillator is altered or , "in accordance with the of a modulating signal." (Dodge and Jersey 1997, p.115)
