Tremolo Plugin Guide

What is Tremolo?

Tremolo is a type of modulation effect that rhythmically varies the volume level of source audio.

In other words, it makes your volume go up and down really fast, or to a particular rhythm.

They were traditionally built into classic guitar amplifiers, but tremolo circuits have since been produced in stompbox or rack processor forms.

Now there are also plenty of tremolo plug-ins available as software options on the market today, some of which are reviewed below.

How Does a Tremolo Plugin Work?

Most tremolo circuits modulate the volume of the signal with a low frequency oscillator or LFO. These can come in a variety of shapes, allowing more specific control over how the volume of the sound ebbs and flows.

Although traditional tremolo designs typically have only sine and triangle LFO waveforms, modern hardware units and software plug-ins can include various other shapes like square, sample and hold, and more.

Features to Look for in a Tremolo Plugin?

Unless you are totally fixated on producing only vintage tremolo sounds, it would be a good idea to look into plug-ins that offer more than your standard sine and triangle LFO shapes.

The availability of square waves, sample and hold, and other esoteric shapes will enable you to produce more strongly-defined and rhythmically-varied tremolo effects.

For modern applications, having the option to sync to MIDI or to set the rate to beat-based values is absolutely essential. While there is something to be said about the ‘natural’ and ‘organic’ vibe resulting from free-running LFOs, being able to set the tremolo rate in time with the song’s tempo is essential for achieving rhythmically-precise results.

That said, let’s take a look at the best tremolo plugins on the market.

For many users, the Soundtoys Tremolator beats out all the rest as far as sound and sheer sound-shaping capabilities are concerned. The powerful control over setting rhythms is subject to frequent praise, and the dynamic real-time expression capabilities simply serve to push it over the edge.
