11 Best Phaser Plugins To Add Air 2024 (And 7 FREE Plugins)

11 Best Phaser Plugins To Add Air (And 7 FREE Plugins) | integraudio.com

This article will discuss the best phaser plugins in 2024, both paid and free, for adding air and a “sweeping” effect to your sounds. 

Phaser plugins are found in almost every DAW in their stock plugins list. However, the functionalities and depth of tweakability and control vary from plugin to plugin. Since it’s a creative effect, each plugin and control can impart a unique texture to your sounds. Hence, you must have various phasers in your plugin arsenal. 

How do phaser plugins work?

When an audio signal passes through a phaser plugin, the plugin splits the audio into two parallel paths. In one path, the audio passes through several all-pass filters, which shifts the phase of several frequencies and ranges.

The first path preserves the signal, and then the signals from both paths are added such that some phase-shifted frequencies are canceled out, and some are added with the frequencies in the original signal.

That creates notches and dips in frequencies in the output, resulting in the classic phaser sound! Usually, you get an LFO in the plugin that affects how the waveform is modulated and how the notches and dips are created.

Sometimes, you may also get a feedback control that feeds the modulated signal (signal passed through several all-pass filters) back into the all-pass filters

Lastly, a control called “Stages” in many phaser plugins can alter the number of all-pass filters that create the phase shifts in different frequencies in different proportions.  

Why phaser is helpful in music production?

Phasers are helpful in music production for creating more movements, textures, space, depth, stereo width, etc. (informally termed as “swirling” or “sweeping” effects amongst producers), which can be useful for creative effects/processing or for adding subtle or elaborate musical expression, to your sound design and songs.

Phasers are also commonly found in guitar and bass FX pedals and amplifiers. 

David Gilmour (Pink Floyd), Eddie Van Halen (Van Halen), Jimi Hendrix, Brian May (Queen), etc., are among many famous guitarists who extensively use phaser effects. Amongst modern artists, Tame Impala and Radiohead have a phaser effect in their signature sound.

Many rappers like Kanye West, Childish Gambino, Tyler, Frank Ocean, Kid Cudi, Kendrick Lamar, etc., use this effect subtly and artistically use these effects in instruments and vocals.

Next, with its Stage knob, you can also tailor the number of filter stages utilized in the modulation section. Its Skew Parameter manipulates the LFO’s waveform shape, enabling the alteration of the LFO’s phase and symmetry, providing detailed modulation patterns and tonal variations.

Further, CHOW Phaser’s Thrash Option introduces additional styles of nonlinear processing to the feedback stage. Next, you can manage the overall modulation effect applied by the LFO, allowing for adjustments in speed, intensity, and rhythmic pattern of the phaser effect.

The Feedback Knob in the plugin lets you control the level of feedback within the phaser circuit, influencing the resonance and intensity of the effect, contributing to pronounced or subtle tonal changes. You can fine-tune the intensity or range of the modulation depth, providing control over the phaser effect’s impact on the audio signal, from gentle modulation to profound depth and movement.


CHOW Phaser is available in VST, VST3, and AU formats and as a standalone plugin and is compatible with macOS 10.12 Sierra or newer (Intel / M1 Apple Silicon supported) and Windows 7 or newer operating systems.

11 Best Phaser Plugins To Add Air (And 7 FREE Plugins) | integraudio.com

PHASIS by Native Instruments is a part of the MOD pack Effects Series by Native Instruments. It is a plugin for phasing effects to add momentum and depth to sounds.

Drawing inspiration from classic phasers, PHASIS has two main modes: Spread and Ultra. The Spread control alters notches’ spacing, offering vocal-style effects, while the Ultra mode delivers FM-esque tones at ultra-high rates, adding unique sonic dimensions to your soundscapes.

Key Features:

PHASIS introduces a distinctive Spread feature, altering spectral notches’ density for formant-style and wah-wah effects, offering a sonic signature unparalleled in phaser effects. This control, whether set statically, automated, or inverted, redefines phasing and vowel filtering, adding a fresh dimension to sound manipulation.

Engaging the Ultra mode unlocks modulation speeds with elevating rates to 477.3kHz. This Ultra feature transforms white noise and other signals into mesmerizing FM-style tones, pushing the boundaries of sonic manipulation and delivering innovative soundscapes.

PHASIS combines up to 12 notches, powerful stereo spreading functions, extensive tempo-sync options, and comprehensive professional controls. This arsenal equips you with a formidable modulation device.

Lastly, the plugin offers many dynamic controls for in-depth sound manipulation. Its Rate control governs modulation speed, allowing diverse rhythmic adjustments, and the Center enables precise frequency targeting. You can also adjust the Feedback for resonance intensity and Amount for modulation strength, sculpting the effect’s depth.

Next, the Mod Mix slider balances modulation sources, favoring Spread or other parameters for nuanced stereo field control. Collectively, these controls let you craft intricate phaser effects, from subtle rhythmic shifts to pronounced tonal alterations.


This plugin, as a part of the MOD Pack, is available in AAX, VST, and AU plugin formats and is compatible with macOS 11, 12, or 13 (latest update) and Windows 10/11 operating systems


All phaser plugins have more or less the same controls and functionalities, yet the tone and sound vary from plugin to plugin. That is because of the circuitry emulation and algorithms behind these plugins and the creative nature of the plugins itself. So, selecting which plugin you want to go for could be confusing! 

For that very reason, let’s do a quick roundup! If you’re looking for an analog-style phaser, choose Moog: Moogerfooger MF-103S, Soundtoys’ PhaseMistress, Instant Phaser MK II, and Clearmountain’s Phases. PhaseMistress is also quite versatile and advanced! I recommend this plugin for its well-designed presets and detailed sound design capabilities

If you want an effect plugin for your guitars and synths, Arturia Phaser BI-TRON, Kuassa Efektor PH3605, and Softube Fix Phaser are some options with pedal-like functionalities and sound. Next, Sinevibes Whirl is a great experimental plugin with an interesting workflow that you can use for inspiration and creativity! 

Further, the BLEASS Phaser is great for interesting modulation effects and in-depth tweaking of the phaser sound! Lastly, UVI Phasor is also quite versatile and could be a good multi-purpose phaser plugin
