Basics & Definitions

Question 1

What is FM Synthesis?

Answer 1

Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator.

Question 2

What sounds can FM synthesis create?

Answer 2

FM synthesis can create both harmonic and inharmonic sounds.

Question 3

Describe frequency modulation

Answer 3

Simply put, FM synthesis uses one signal called, the “modulator” to modulate the pitch of another signal, the “carrier”, that’s in the same or a similar audio range.

This creates brand new frequency information in the resulting sound, changing the timbre without the use of filters.
