Amplitude modulation plugins vary the volume of your signal. Tremolo is an amplitude modulation effect. In this article I’ll go through all the common types of modulation, how they work and the best modulation plugins for each. Modulation LFOs work similarly to how LFOs are used in synthesis. The style of modulation is different depending on whether the LFO is manipulating the pitch, timing or volume of the signal.
They all achieve their effect by modulating an aspect of the signal with an LFO (low frequency oscillator). The main types of modulation are Tremolo, Ring Mod, Chorus, Phaser and Flanger.ĭespite the different types, all modulation effects have something in common… They’re the special way to add movement and groove to sounds that need a little something extra. Modulation audio effects are an important part of your mixing toolkit.
