Here are the best free phaser VST plugins online that can be used with FL Studio, Reason, Ableton Live, and other VST-supported software.
In this collection of free Phaser plugins, I’ve included feature lists, screenshots, and videos to showcase how the plugins function.
What is a Phaser VST Plugin? Phaser VST Plugins can be used to add phaser effects to your sound in a VST host. A phaser is a type of effects unit that modifies the sound of an audio signal. It is an effect in which two opposing audio signals are mixed together. It is often used with a synthesizer to create the classic phaser sweep effect.

Frequently Asked Questions
How Does a Phaser Effect Work?
A phaser filters out some of the frequencies of an audio signal, making it sound like it has been mixed with a “swooshing” sound. The original frequencies are still there but are combined with the “sweeping” sound to make it appear as though they are being played in stereo.
The free audio plugins above are all great alternative options to paid plugins, such as Instant Phaser Mk II by Eventide Audio, Audiothing Phase Motion, and the Soundtoys PhaseMistress audio plugin.
I hope you enjoy these free phaser VST plugins.
