To try this out in a modular context it will require at least two oscillators and a VCA. If your modulator is sped up to audio rates, however, strange harmonics will begin to emerge because your modulator is now fast enough to manipulate individual cycles of the carrier’s signal, effectively adjusting its wave shape. If your modulator signal is running slowly, such as at LFO rate, then you will hear the carrier get quieter and louder – this is often called tremolo. The technical way to describe the AM process involves an initial oscillator called the carrier, which is what gets heard in the traditional way, while the second oscillator, called the modulator, is not directly heard but instead modulates (changes) the volume of the first oscillator. volume) create sound?
