With subtractive synthesis, you can easily change the characteristic of a sound by changing the sound source—in other words, by changing the source waveform.

However, subtractive synthesis is not the only way to create sounds. For instance, you could use:

  • Additive techniques, where you bring together a number of waves to create a wholly new tone

  • Modulation techniques (such as frequency modulation synthesis), where one waveform distorts another wave to create a radically different sound
