6 Best Flanger Plugins 2024 (And 6 Best FREE Flangers)

Top 6 Flanger Plugins (And 5 Best FREE Flanger Emulators) - Integraudio.com

In this roundup, we will talk about the best flanger plugins in 2024 as well as 6 of the best free flanger effects, so let’s get on it!

The flanger is a time-based effect that creates a whooshing sound.  It’s more complex than a simple delay but still relatively easy to use. This effect has been used in countless songs over the years to give them an otherworldly feel and add an extra dimension to the sound.

In a nutshell, here are the best flanger plugins in 2024:

1. Eventide Instant Flanger Mk II

2. Arturia Flanger BL-20

3. D16 Group Antresol

4. Audiority Electric Matter

5. Brainworx ADA Flanger

6. MeldaProduction MFlangerMB

The flanger effect is one of the most widely used audio effects and can be heard on countless recordings of different styles and genres.  However, even though it’s used on so many things, flanging is not often evident for everyone to hear it. Instead, most of the time, engineers and producers use it as a subtlety, turning it into one of many texture layers that make a recording sound good.

On the other hand, sound designers often use it along with different effects, like chorus and phasers, in many creative ways to fabricate specific sounds that go with a particular feeling or image they need to represent. Flangers can also be the start of an entirely different effect than what we’re used to hearing due to the experimentation with its parameters.

Top 6 Flanger Plugins 2024

1. Eventide Instant Flanger Mk II

More Info & Price (Trial Available)

Instant Flanger is an analog recreation of the original Instant Flanger from 1979.

The Eventide Instant Flanger Mk II combines two classic effectsthe Flanger and the phaser. It has a rich psychedelic sound with a very musical distortion that works terrific on a clean rock guitar; it would sound like David Gilmour’s guitar tone in Pink Floyd’s “Hey You” song. 

This hardware emulator features controls for sweep rate and feedback and a select switch that allows you to choose between analog or digital modes. Let’s take a look at this plugin’s key features.

Eventide Instant Flanger Mk II Review - Top 6 Flanger Plugins (And 5 Best FREE Flanger Emulators) | Integraudio.com

Key Features:

  • 3 Different flavors

Instant Flanger Mk II offers you three flanging modes: shallow, deep, or wide. The Shallow mode is perfect for subtle flanging, while the Deep mode can create a more dramatic effect. The Wide mode gives you that classic jet plane flange sound. You can also adjust the flanger’s rate, and depth controls to change the sound.

  • Bounce Knob

The bounce knob replicates the effect of the tape’s reel motors bouncing when you release them after slowing them down. Unlike the original Instant Flanger, which used an LFO to modulate the delay time, this updated version uses a feedback loop which significantly enhances its sound.

The high-frequency roll-off and low-frequency resonance controls have also been updated to provide more tonal variation.

  • Modulation sources

The Instant Flanger can be controlled by four modulation sources that you can combine for even more variety. The oscillator mode, which is straight-up classic LFO flanging with a variable rate, the manual control mode, gives you manual control over the delay time.

The envelope follower mode controls the flanging by the level of the input signal, and finally, the remote mode enables MIDI control over the flanging.

Eventide Instant Flanger Mk II Presets Demo


Supports Windows 8 and higher, Supports macOS 10.9 or higher, runs on 32 and 64 bit, and comes in VST2, VST3, AU, and AAX formats.


Eventide’s Instant Flanger MkII plugin emulates hardware from the ’70s and ’80s and features warm analog-like characteristics. For both live and studio situations, this plugin will deliver outstanding results with an analog flavor, but keep in mind it’s not too subtle.

Eventide’s Instant Flanger MkII plugin also features an adjustable stereo width control to allow users to adjust the sound to their liking.

2. Arturia Flanger BL-20

More Info & Price (Trial Available)

Arturia Flanger BL-20 lets you create your own control patterns.

Key Features:

  • Stereo Enhancer:

It has a stereo enhancer, which can operate in either mono or stereo mode. You can use the stereo enhancer in mono mode to enhance the bass response of a mix. In stereo mode, the left and right channels are processed separately to produce a wide, three-dimensional sound that enhances the sense of space.

  • Advanced Controls:

The plugin adds a new dimension to the familiar flanger. This pedal goes beyond the standard principles of flangers by adding cutting-edge controls that encourage users to explore the potentials of the sound, like the hi-pass filter and the LFO shaper, which allow you to switch between sine, square, sawtooth, and reverse sawtooth.

You can also trigger the envelope follower using external sources.

  • Presets:

This release provides you with 28 presets, which are all excellent for different textures, and you can switch between three modulation sources: LFO, ENV (including internal and external), and manual, or try different combinations of them.

D16 Group Antresol Review - Top 6 Flanger Plugins (And 5 Best FREE Flanger Emulators) | Integraudio.com

Key Features:

  • New and improved:

D16 group went the extra mile when making their emulation of the legendary Antresol Flanger. They’ve given us a ton of new functions like selectable and unlikable L/R or M/S processing modes, a tag-based preset browser, individual stereo channel controls, and even a “mistress” mode that makes it work the same as its analog version.

  • Tempo sync:

The LFO in Antresol can optionally synchronize the frequency and phase of oscillation with the host application’s tempo. The Tempo Sync parameter is used to activate this function. You can set it to one out of four values: off, full, triplet, and dotted.

  • Store your presets:

Antresol comes with several presets, but the exciting part is that you can store your own. The plugin has a tag-based browser that allows you to keep your presets as files on your computer. Each time you load it, Antresol scans these folders, and all presets are consolidated in a linear structure in the browser.

4. Audiority Electric Matter

More Info & Price (Trial Available)

6 Best Flanger Plugins 2024 (And 6 Best FREE Flangers) - 2024 Update

Electric Matter is a meticulously designed emulation of the renowned Electro-Harmonix Deluxe Electric Mistress.

This iconic flanger and filter matrix pedal from the late 1970s relied on the Reticon SAD1024 BBD chip; artists from all genres have chosen this flanger for its capacity to add subtle, dreamy nuances to lead lines or to replicate the mesmerizing rotation effect of a Leslie speaker.

It has a great LFO and VCO circuitry that broadens the palette of possible settings so electric Matter progresses beyond its hardware counterpart by eliminating typical complications such as diminished tonality and volume reduction.

Key Features:

  • BBD Analog Flanger Simulation

At the heart of Electric Matter lies its BBD Analog Flanger Simulation, meticulously designed to reproduce the lush, characteristic tone of the classic bucket-brigade device (BBD) flangers. This feature emulates the analog delay lines used in the original units, creating sweeping sonic textures that give flange effects their unique feel.

By adjusting the delay time, you can emulate everything from the slow, dreamy modulation of classic tape flange to the rapid oscillations of more intense flange effects.

  • Color, Range, and Rate Controls

These are the primary controls for shaping the flanger effect in Electric Matter. The Color control adjusts the overall tonal quality of the flanger, affecting how bright or dark the effect is. This allows for a wide array of tonal possibilities, letting you cater the flanger effect to suit the sound you’re working with.

The Range control, on the other hand, alters the breadth of the flanger sweep, dictating how wide or narrow the movement of the flange effect is. This control allows you to produce everything from broad, sweeping flange effects to narrow, more subtle shifts.

Finally, the Rate control determines the speed of the flanger’s oscillation, setting how quickly or slowly the flange effect sweeps back and forth. By manipulating this control, you can create dynamic flange effects, from slow, evolving textures to rapid, pulsating modulations.

  • Filter Matrix Mode

The Filter Matrix Mode is a unique feature of Electric Matter, offering the ability to freeze the flanger sweep and create static flange effects.

This means you can set the flange effect at a specific point and leave it there, creating resonant, comb-filter-type effects or abstract, metallic textures. This feature provides control and flexibility not typically found in traditional flanger units, opening up new avenues of sonic experimentation.

  • Tempo Sync

The Tempo Sync feature is a significant addition to Electric Matter. This allows the rate of the flange effect to be synced to the tempo of your track, ensuring that the effect moves in time with your music.

This feature is particularly useful for rhythmically complex or tempo-synced flange effects, ensuring that the flange always lands exactly where you want it to in the rhythm of your track.

  • Pre and Post Effect Gain

The Pre and Post Effect Gain controls allow you to balance the volume levels before and after applying the flange effect. This feature is crucial in overcoming the volume drop issues often associated with similar hardware units, providing you with complete control over the loudness of your signal at every stage of the effect chain.


Audiority Electric Matter is available for Windows 7 or higher and macOS 10.12 or higherboth 64-bit only. It comes in VST, AU, and AAX formats.


Audiority’s Electric Matter is more than just another flanger plugin—it’s a great, comprehensive sound-shaping toolset to become a mainstay in the music producer’s toolkit. Its rich features provide great control, enabling you to cultivate many distinctive flanger effects.

Its strength lies in its ability to perfectly balance the revered analog flanger qualities with the flexibility of digital sound manipulation. This balance allows you to create an almost limitless array of unique sonic textures. In an era of cookie-cutter plugins, Electric Matter shines bright, offering a truly innovative approach to the flanger effect.

5. Brainworx ADA Flanger

More Info & Price (Trial Available)

ADA Flanger is an accurate recreation of the classic A/DA Flanger, one of the first commercially produced flanging effect pedals.

This plugin sounds different from your standard flange plugin because it uses a digital model of a classic analog effect. As the name suggests, it’s based on the classic A/DA Flanger effect that has been around for decades. It has a very musical quality to it. It’s not as aggressive as some other flange plugins, which is good if you want to have more control over the depth and breadth of the effect.

It has three flange modes, you can create some truly unique effects that are nothing short of breathtaking. With its multiple modes, you can quickly go from a subtle, modulated tone to a full-on jet engine effect that will take your mixes to the next level.

Brainworx ADA Flanger Review - Top 6 Flanger Plugins (And 5 Best FREE Flanger Emulators) | Integraudio.com

Key Features:

  • Unique sound:

A/DA Flanger is made after a classic pedal effect of the same name that was particularly famous in the ’80s. The plugin sounds and reacts the same way as both analog pairs, the original from 1979 and the re-issued pedal, making it a great option if you’re aiming for a vintage sound or just trying to add a subtle color to your mixes.

  • High delay ratio:

Knowing that most flanger plugins reach up to a 20:1 delay ratio, Brainworks saw a window of opportunity to make their A/DA Flanger stick out by doubling the offer. The plugin reaches up to a 40:1 delay ratio, giving you a broader pallet of entirely new sounds and possibilities that just aren’t possible with a lower ratio.

  • More control:

A/DA flanger offers a set of control that allows you to be as precise as you can when adjusting the flanger. It includes a threshold control that works as a gating effect, a “manualknob that defines the tonal center of the sweep frequency.

The range modifies the frequency spectrum of the flange, you can also set the speed, and there’s the Enhance knob, a resonance control capable of adding depth and intensity.

  • Exclusive features:

After recreating to the finest detail the sound of the analog pedal, Brainworks didn’t stop and included some cool features of their own. The Wet/Dry Mix control is one of these exclusive features of the plugin, and it allows you to load it as an insert to different elements in the mix and balance how much of the effect you want each time.

You can also tempo-sync with your project session and access dual stereo modes, making A/DA a great tool for stereo enhancement.

NI Mod Pack Review - Top 6 Flanger Plugins (And 5 Best FREE Flanger Emulators) | Integraudio.com

Key Features:

  • Chorus modes:

Choral is the chorus effect component included in this effect pack and lets you switch between four different sound modes. The Universal mode provides a clean, modern digital sound. Synth mode has a resembling sound of a series of synthesizers from the ’80s that were famous for their “unison” chorusing function.

The ensemble mode resembles the BBD chorus section of a legendary string synth from the late ’70s. Lastly, the Dimension mode takes its sound from a classic rackmount chorus.

  • Flair modes:

Just like Choral, Flair gives you the possibility of choosing one of three modes: Standard mode keeps each voice behaving like any other flanger effect. The In Thru mode, which duplicates each voice at its particular pitch without modulating the duplicates, makes the flanging more evident as the modulation increases.

Last but not least, we have the In Scan mode, which plays the voices consecutively with an order set by one of three waveforms.

  • Sound enhancement:

Flair also includes sound-enhancing features such as Detune to offset the pitch of the flanging, and feedback, which thickens the flanging, including adjustable damping control and softening the effect at high feedback values.

  • ULTRA:

Ultra is a feature available in Phasis, the third component of this package. By engaging ULTRA, you raise the maximum modulation speed from 8.37KHZ up to 477.3KHZ, enabling you to create FM-style effects and even transform white noise into an entirely new sound.

Waves Kaleidoscopes Review - Top 6 Flanger Plugins (And 5 Best FREE Flanger Emulators) | Integraudio.com

Key Features:

  • Analog inspiration:

Waves audio took a bunch of famous vintage analog units, pedals, and tape FX from different eras and modeled them into Kaleidoscopes. They’ve made a literal “best of” collection to give this plugin a unique sound response packed up in a versatile, powerful tool.

  • Serial or Parallel effect processing:

Kaleidoscopes has a so-called Dual Cascade architecture that gives you two different effect engines. This feature enables the possibility of both serial and parallel processing, allowing you to either feed one engine into the other or keep them both active and achieve broader textures.

  • Intelligent triggering:

Waves Audio is always thinking about their buyers, which is why they’ve developed an intelligent triggering for musicians to use this plugin as part of their effect board. The input-sensitive envelopes respond dynamically to your playing, modifying its character in real-time based on your performance.

Audio Damage Quatro Mod Review - Top 6 Flanger Plugins (And 5 Best FREE Flanger Emulators) | Integraudio.com

Key Features:

  • Through-zero flanger:

The built-in flanger effect in Quatro Mod features a Haas effect offset control and enables you to invert feedback to create a wider sense of space. This feature is a killer for film scoring because you can create a deep, immersive atmosphere by playing with the offset to affect the stereo image.

  • Chrous Mode:

The chorus mode is based on Audio Damage’s original plugin, Fluid. It has six delayed lines modulated at different rates, which creates its characteristic thick stereo chorus sound. 

  • Diffusor FX:

Quatro Mod’s diffusor is the recreation of their original Vapor plugin. It works as a diffusion block from a reverb, but it’s rewired to create a chorus sound. This diffusor works amazingly on drums. I suggest trying it out in room mics, snares, or applied subtly on overheads.

  • Frequency Shift:

The frequency shift (“freqshift”) mode differs from all other modulation effects that come with Quatro Mod, as it was modeled after one of Audio Damage’s Eurorack-format hardware modules. It’s recommended to use this mode in pads, synths, or any mid-frequency-based instrument, but you can try it out on any signal and see how it works.


Supports Windows 8.1 and higher, Supports macOS 10.8 or higher, runs on 32 and 64 bit, and comes in VST2, VST3, AU, and AAX formats.


Quatro Mod by Audio Damage is a plugin with everything you need to create innovative textures for your music, scores, and sound effects. It delivers an easy-on-the-eye layout and four great-sounding modulators that can go from a subtle color on your vocals to a crazy dark ambiance on your score.

This plugin is a killer for sound designersbut it’s also great for music production and mixing.

How does Flanger work?

A flanger works by mixing two identical signals, one of them is dry, but the second is delayed with a very short delay time and modulated with an LFO (low filter envelope). The sum of these two signals creates interference and a series of notches in the frequency spectrum. This alteration of the frequency spectrum is known as a comb filter.

These notches will usually occur in harmonic-related intervals in the upper frequencies, and they can be moved around the spectrum by tweaking the LFO parameters. Another parameter found in the flanger processors is the feedback.

Its function is to send the output back to the input to receive more processing. This recirculation of the delay will produce a resonance effect that will accentuate the notches and give a different timber to the flanger.

How do you use the flanger effect in your music?

You can use a flanger effect on any track to create a unique texture, for example, on specific instruments, like guitars, bass, or piano. That will get your listeners to pay attention to that instrument and notice something they might not have before.

Another way to use a flanger effect is in a subtle way in the background of a song and blend it to your overall sound. That will give it an interesting touch. You can also use it on vocals and raps, especially if you’re mixing.

Who invented flanger?

The invention of the flanger is usually attributed to Les Paul. In the late 1940s, he came up with this technique by using two disk recorders and manipulating one of them with variable speed control. Nonetheless, the first recording where we can actually hear a flanger effect is on The Big Hurt, by Toni Fisher (1959).

Does flanger go before or after chorus?

Flanger and Chorus are modulation effects that similarly use delay variations, but they’re different because of the length of the delay time required to create the sound; a chorus needs the longest delay times while a flanger needs the least.


We’ve reached the end of this list. All of these plugins are what we consider to be the best out there. Each one has unique functions that will facilitate an easy adaptation to whatever might be your workflow.

Nonetheless, let’s recap for a second about all of this information to help you out when making a decision.

The best tools on this list for sound designers are the Arturia BL-20Melda Production’s MFlangerMB, KiloHearts’ Flanger, Imaginando DLYM, D16’s Antresol, and Quatro Mod, by Audio Damage.

Some tools just work perfectly with everything because they have so many different characteristics that you can quickly adapt them to any given case. Waves Audio’s Kaleidoscopes, Valhalla Space Modulator, and NI Mod Pack are perfect examples for absolute versatility and adaptation.

Finally, some tools are simply perfect for music producers and mix engineers. Such tools exist to deliver a more musical flanger that gets the job done without much complication. Eventide’s Instant Fanger, Blue Cat’s Flanger, TAL-Flanger, Brainworks A/DA Flanger, and the HY-Cho/Fla are the best for the task.
