Explaining Why Subtractive Synthesizers Don't Have Sine Waves #
Mar 07, 2023 Tutorial
In this video, I explain why there is no sine wave in a classical subtractive synthesizer. This is because sine wave has no overtones and therefore makes no sense in terms of subtractive synthesis. I explain how the filter section can be used to target and amplify the fundamental frequency as well as other partials in the harmonic series. I also provide an overview of other synthesis methods such as additive synthesis, Wavetable synthesis, FM synthesis, phase distortion, vector synthesis, granular synthesis, and physical modeling. In each of these methods, sine waves make more sense. Finally, I explain why a saw and pulse waveforms are used in polysynth - because they give different harmonic overtones.
