Synthesis Methods

In the so called subtractive synthesis oscillators create a certain frequency spectrum and in the next steps of the synthesis some frequencies are cut out of the spectrum by filters. This is in contrast to the additive synthesis, where the sound is created by addition of sine waves. In frequency modulation  (FM) synthesis the idea is to modulate the frequencies of the oscillators by other oscillators to create particular sounds.
