The 9 Best Filter Plugins For Precise Mixing 2025

Filters have become an integral part of music production ever since they appeared in hardware form. From the classic analog goodness to the ultra-flexible modern filters, we cover eight of the best filter plugins you could buy and five timeless free ones in this article.

Filters find their use during mixing and mastering, sound designing, and sometimes even audio recording. Let’s look into filters in more detail:

A filter is a plugin that removes a specific part(s) of your audio’s frequency spectrum in a way you specify. For example, a second-order high pass filter at 200Hz attenuates all the frequencies below 200Hz with a slope of 12dB per octave.

However, that’s not all a dedicated filter does. Some filter plugins have a specialized sound built into them – using saturation and slope shapes to emulate an analog filter is one of the most common types.

Similarly, some offer gating and modulation features along with filters. These kinds of filters are one of the biggest timesavers, especially if you are producing electronic music.

To understand further, the regular EQ plugins we are familiar with are, in fact, collections of a variety of filters like a cut-off, notch, bandpass, and band-stop. However, when we talk about filters, we generally mean cut-offs and bandpasses with much more control, variety, and drastic manipulation.

Note: To keep this article concise, we’ve provided a brief overview of each plugin. For complete details and features, we recommend checking the official product pages.

1. Polyverse Filterverse

I loaded up Filterverse expecting just another filter plugin, and five minutes later, I was deep in modulation chaos, wondering why my kick drum was singing vowel sounds at me.

This isn’t your typical frequency-cutting tool as it’s like someone gave a modular synth a filter obsession and a paintbrush. You can go subtle if you want, sure, but honestly, I usually end up creating sonic mayhem (in a good way).

The Filterverse layout’s got that “spaceship control panel” vibe at first, but it’s not as overwhelming as it looks. You get 3 filter slots stacked up top, 8 modulation sources below, and a routing matrix that makes sense once you mess with it for a minute.

Also, I gotta give credit to the color-coded interface, it helps keep my brain from melting when I’ve got half a dozen things modulating each other.

• Filter Types

There are over 25 filter models, and this thing doesn’t stop at low-pass and high-pass. You get freaky stuff like Vowel, Robo Comb, String, and more.

I slapped the Vowel filter on a vocal chop and suddenly it was mumbling like a synth possessed. Stack three of the same type or mix-and-match, whatever gets you the weirdest result (which, for me, is always the goal).

• Modulation Sources

Filterverse gives you LFOs, step sequencers, envelopes, random generators, and even pitch tracking. And you can throw any of them on basically anything.

One of my go-to moves? Using the envelope follower to modulate a comb filter on a snare. It adds this weird shimmer that rides the transient like it knows what it’s doing. Also, the Meta Knob is a lifesaver. Assign it to a bunch of stuff and sweep it for those “DJ filter sweep on another planet” moments.

• Routing and Assignment

Modulating stuff is actually pretty painless. You just click a parameter, pick a source, and you’re good to go.

Everything’s visual and interactive with a drag-and-drop style workflow. So even if you’re not a modulation wizard, you won’t get lost. I figured it out faster than I expected (and I’ve definitely gotten lost in worse UIs).

• Preset Library

You get 700+ presets, and they’re not just filler. Some are chill and usable right away, others are pure chaos either way, they’re great for inspiration. I’ve picked apart a bunch just to see how they set things up. Honestly, I’ve stolen more modulation tricks from these than I care to admit.

Filterverse isn’t trying to be subtle. It’s a creative filter tool that wants you to get weird, twist sounds, and experiment. I reach for it when I’m stuck, or when a sound feels flat and I want to throw it into a blender. Most of the time, I don’t even know where I’m going with it and that’s half the fun.

Polyverse is available in VST, AU, and AAX formats for macOS and Windows.

2. SoundToys FilterFreak 2

From silky-smooth filters to overdriven hardware saturation, give your audio the analog touch with this plugin.

FilterFreak 2 is a highly configurable resonant filter plug-in that combines the sounds of vintage filter units with modern versatility. It has two filter modules capable of performing low-pass, high-pass, band-pass, and notch filtering. Furthermore, it also offers “pole” switches to control the filter slope steepness.

Similarly, there are plenty of modulation sources available in this plugin, and each offers in-depth editing to create customized sweeps, sci-fi laser effects, or gated riser effects.

Key Features:

• Analog Filters

Each filter type in FilterFreak 2 has been carefully designed to sound and react like real, hardware analog filters. Sweeping around with the filter knob creates no unwanted artifacts, and you can select different pole values ranging from 2 to 8 in pairs.

• Parallel or Serial

You can set the filters routed in either parallel mode or serial mode. And since this is an analog emulation, you will hear distinct character changes when you switch between the modes, more than a typical filter plugin.

• Rhythm Mode

If you click on the white button on the fourth section of the plugin, you can switch to various modulators available in this plugin, and one of them is the Rhythm Mode.

• Even More Modulators

Other than the Rhythm Mode, five more modulator types are available in the plugin: LFO, Envelope, Random, Step, and ADSR. Filterfreak 2 does not accept sidechain input for either Envelope or ADSR; instead, you will be using the main audio input and a threshold for the ADSR. However, it does accept midi inputs for midi-triggering.

3. SlateDigital Storch Filter 

Storch Filter is a multi-fx plugin developed by SlateDigital and award-winning producer Scott Storch.

With 5 built-in effects and customizable presets from Scott himself, Storch Filter consists of reverb, chorus, saturation, stereo widening, and phaser, all linked to the plugin’s cutoff and resonance knobs.

Key Features:

• Built-In Effects Suite

The plugin’s FX design allows you to shape your sounds dynamically; as you modify the filter settings, the associated effects adjust correspondingly, enabling rich and varied sonic textures. The FX Boost slider adds further depth, producing bolder, more colorful auditory results.

• Onboard Autofilter

Featuring a sophisticated onboard auto filter, Storch Filter lets you manipulate your filtered signals with 6 selectable wave shapes, along with adjustable filter types and slopes (1x, 2x, 4x, and 6x). You can easily fine-tune the rate, depth, and phase parameters to create desired effects, from subtle pulsing to pronounced pumping grooves.

• Pro-Designed Presets

Storch Filter offers instant inspiration through a comprehensive collection of presets designed by Scott Storch himself. These presets are put together into 4 categories: Drums, Bass, FX, and Instruments.

Compatibility:

SlateDigital Storch Filter is available in VST2/3, AU, and AAX plugin formats for macOS 10.15 or later (macOS 11 or later) and Windows 10 or 11 operating systems.

4. FabFilter Volcano 3 

Volcano 3 sports a complete overhaul over its previous iteration of this creative filter plugin with a fiery user interface, better filters, and even more flexibility.

First released back in 2005, this 2021 version of the Volcano filter plugin is filled to the brim with features. Despite its incredibly futuristic and digital user interface, the filter plugin boasts a vintage-style gritty and creamy sound. And if I’ve learned anything from reviewing FabFilter plugins, things are bound to get quite complicated as we dive in.

Let’s talk about the user interface. Volcano 3 features three main sections from top to bottom on its UI: the filter display, the controls, and the modulation section. The filter display resembles a parametric EQ and shows each filter you’ve added.

Similarly, the filter controls let you change the settings for the selected filter. And lastly, the modulation section shows all the modulation sources that can generate highly creative results.

Key Features:

• Multiple Filters

The filter display section is an interactive display that lets you add up to four analog-modeled, self-oscillating filters. You can effortlessly create a new filter by double-clicking on the frequency spectrum.

Likewise, you can change the frequency and resonance of each filter using your mouse. And a small pop-up lets you change the filter shape and pan of each filter. Furthermore, you can add a low-cut or a high-cut filter by double-clicking on the left or right edge of the frequency spectrum.

• Routing

The middle section of this plugin holds the filter controls. And you’ll find the Routing controls on the left part of this section. Here, you can change how the filters are connected and the plugin’s channel mode.

• Grit and Style

Each filter offers a drive knob that controls the input drive of the filter. You can increase it to make the filter grittier and saturated. Similarly, the Style button reveals a menu of eleven types of filters, each with a distinct flavor: Classic, Smooth, Raw, Hard, Hollow, Extreme, Gentle, Tube, Metal, Easy Going and Clean.

• Modulation

First, you can add a delay of up to 50ms on each filter. This feature allows you to combine the sound with other filters parallelly and create the Haas, chorus, and flanging effects. However, you’ll need to modulate the filters to get creative and moving results.

Volcano 3 offers five types of modulation sources, which can modulate just about any parameter on the interface. These sources include XLFO, envelope generator, envelope follower, MIDI, and XY controller.

5. Polyverse Supermodal

Polyverse Supermodal is a dedicated filter based on a twin-filter engine; they operate in parallel and are very different.

Its great Modal filter alters your tracks, which imitates the sound of various resonant bodies. With a parallel state-variable filter and a large modulation system, a single audio input can be changed into a wide range of frequencies to make shimmering dramatic landscapes, pulsing beats, pads with harmonic motion, or anything else you can think of.

Key Features:

• Models

It has 27 modes with different resonances, called Variants, and they are grouped into 9 filter models that emulate familiar objects, instruments, and sounds, as well as non-traditional sounds.

They have fluid controls like a spherical control in the middle that shows all the patterns, which you can set using slider points.

• Input And Output

You have controls that help us alter the Output and Input of the plugin and control that represents Wet/Dry. Along with Drive, all these controls can be locked using the lock button next to the slider.

• Filter Mode

This filter that you can find in Supermodal is complemented by a variable filter equipped with 3 modes, a fixed flop of 24dB per octave, and an algorithm that handles saturation. These two filters (modal and standard) are arranged in parallel, so you can easily alter them together.

• Modulation

Supermodal incorporates Polyverse’s Manipulator plugin’s modulation component, making it powerful. The 6 modulation sources—envelope follower, sequencer, ADSR envelope, randomizer, and MIDI input—can be assigned to the 4 modulation slots. The generators may cross-modulate and modulate most plugin parameters.

• Controls

The plugin is divided into two parts: the top holds the main controls, and the bottom has 4 compartments, each holding 6 modifiers. All the controls on the small screen have an image that transforms with a parameter for a real-time visual impact.

6. Waves Metafilter

Waves MetaFilter is a sound-shaping filter plugin with their Virtual Voltage technology for analog sound.

There is a single filter module in this plugin. And it is designed to deliver the warmth and fatness of classic analog filters while being paired with modern control and flexibility. You can modulate the filter’s cutoff, resonance, and delay time using three separate modulators.

The filter section has low-pass, high-pass, band-pass, comb, and gain options. The gain option could be used to get gating, stuttering, and ducking effects when paired with the sequencer. It also offers sound design tools like a stereo enhancer, a saturator, and a resampler.

Key Features:

• Analog Sounds

MetaFilter uses Waves’ Virtual Voltage technology to emulate analog hardware units. This feature gives the entire plugin a very earthy sound. The plugin also features a Drive parameter to add further to the analog vibe, which overdrives the filter unit to give saturation to your audio.

• 3 Modulators

Meta Filter has an LFO, a step sequencer, and an envelope follower. The step sequencer can have up to 16 steps, as shown in the picture. And the envelope follower can either react to the main audio input or a sidechain input. Setting it to react to the main audio input is a great way to get a quick and easy “wah-wah” effect.

• A Delay Unit

This filter plugin also sports a delay unit. It can be synced to your tempo or not, and you can also offset the right output channel to give it an enveloping sound. There’s an “Analog” button on the left side of the delay section, making the delay time parameter smoother.

So, you can then automate it without artifacts. The Route button switches the delay from being routed before the filter or set in a feedback loop.

7. Rift Filter Lite

Rift Filter Lite is a modern filter plugin for producers to shape and manipulate audio signals.

It includes various filter types and modes, such as high-pass, low-pass, band-pass, and notch filters.

The plugin also features a comprehensive effects section, including distortion, EQ, and delay effects, allowing you to add more processing to your filtered sound. Its user-friendly interface provides visual feedback on the settings and adjustments, making navigating and using the plugin easy.

Key Features:

• Resonance & Drive control

You can adjust the filters’ resonance, creating a unique sound and adding character to the audio. Further, its drive control feature allows you to add saturation to the audio, which can add warmth and harmonic distortion to the sound.

• LFO modulation

The plugin includes an LFO (Low-Frequency Oscillator) modulation feature that allows you to create dynamic and evolving filter effects by adjusting the speed and depth of the modulation.

• Intuitive interface

With a user-friendly interface, the filter is easy to navigate and use. Its interface includes visual representations of the filters and modulation settings, allowing quick and easy adjustments.

• Low CPU usage

Designed to be lightweight and efficient, with low CPU usage, the plugin ensures smooth and responsive audio processing even on less powerful systems.

9. UVI Shade

UVI Shade is a versatile equalizer/filter capable of advanced modulation and comb filtering.

This plugin goes well beyond the capabilities of traditional equalizers and filters. While we’ve listed it as a filter plugin, it is an EQ on steroids more accurately. Likewise, its drag-and-drop and intuitive workflow make it fast, effective, and superior to many existing products on the market.

Furthermore, it provides a giant collection of presets divided across seven factory categories. These include animated basics, animated complex, color, dynamic, filtering, moving FX, and utility. As you’d expect, the animated presets exploit Shade’s modulation capabilities, turning a simple synth sound into awe-inspiring patterns.

Key Features:

• Filter Types

Shade has thirty-five types of filters available. These are divided into the following groups: low-pass, high-pass, notch, band-pass, high shelf, low shelf, peak, phaser, comb, and special. Each provides multiple options like resonant, multi-resonant, Sallen Key, and Xpander.

• Modulation

You can add an infinite number of modulators to the plugin’s dedicated modulator area. The modulation sources available are as follows: Envelope, Figure, Follower, LFO, Macro, MSEG, Random, Spread, and XY pad. Assigning a modulator is intuitive—right-click a parameter and select the desired modulator from the list.

• Stereo Processing

Each band in Shade provides multiple stereo processing modes: Stereo LR, Stereo MS, Left, Right, Mono/Mid, and Side. As a result, you can apply filters only to the side part of the audio to generate wide, immersive movements.

• Comprehensive

On top of the powerful yet user-friendly EQ and modulation features, Shade provides many other seemingly minor features that help you during music production. For example, it has a built-in limiter that prevents ear or equipment damage when you’re designing complex modulations and filter shapes.

The 5 Best FREE Filter Plugins

Key Features:

2. Noiiz Filter By Noizz

Simplicity at its best.

The Noiize Filter is a unique filter plugin designed to emulate analog filters.  It has four types of filters: high-pass, low-pass, band-pass, and notch. However, the most interesting part we found in this plugin is its noise generator. The noise it generates is designed to mold with your input audio to create interesting effects.

Key Features:

• Analog Filters

There are four types of filters and multiple flavors under each type to reach nine kinds of filters in this plugin. Each filter is designed to emulate the analog shape and character, so the ending result is warm and silky smooth.

• Noise

The noise generator has a huge library of noises you can choose from. It includes unconventional noises like rain to highly-demanded ones like vinyl crackles. So, you could even use this plugin to get Lo-Fi sounds.

• Drive

Since the plugin is an analog emulation, some warm-sounding saturation is crucial as a cherry on top. And Noiize Filter delivers it by offering a convincing overdriven circuit that works with the filter resonance to give beautiful distortion.

3. BPB Dirty Filter

Utilize the BPB Dirty Filter to provide subtle color or crush the audio into fragments.

Bedroom Producers Blog’s BPB Dirty Filter is a freeware plugin with two cutoff filters and replicated analog tube circuits. For the creative sound designers, though, as good as the filters themselves are, the dirty distortion it offers is what opens a world of sonic explorations.

Key Features:

• Versatile

It is a great utility for cleaning up your audio, as it combines a high-pass and a low-pass filter. Both filters feature a frequency range of 20 Hz to 20 kHz with selectable filter slopes. The plugin also has a Mix knob and an output volume control for easy gain staging in your DAW.

• It Plays Dirty

BPB Dirty Filter is a transparent filter plugin when the Drive knob is set to zero. It’s ideal for reducing high-frequency noise or removing low-frequency hum in this mode.

• Lightweight

The BPB Dirty Filter barely makes any impact on a moderately powerful CPU, so you will have no problem loading as many of this plugin as you need. We recommend trying its distortion out on multiple frequency ranges and setting the Mix knob to taste.

4. HY-Filter3

The free version of HY-Filter3 is a creative filter plugin with two unconventional kinds of filtering.

Instead of an individual cutoff or band filter, HY-Filter3 Free offers two types of filters, both of which use a mix of multiple filtering techniques. The plugin also has a saturator, offset for skewering the band, a three-band EQ, and an LFO modulator. Together, they form a powerful sound design tool.

Key Features:

• Type I: SVF

The ‘state variable filter’ allows you to set a filter type between low-pass, band-pass, and high-pass as you want. For example, setting the dial somewhere between LP and BP will give you some high frequencies along with the full sound of the low-pass filter. This technique is incredibly useful to create a milder effect when it comes to filtering your audio.

• Type II: Reso

The Reso type is based on the MAM RS3 Resonator. It uses a complex combination of three band-pass filters and an LFO modulator to give sweeping sound effects. There are three kinds of Reso filters to choose from in this plugin, and you can also set the band-pass filters to any frequencies you want.

• Modulation

The HY-Filter2 Free has a single LFO modulator, which can modulate the filter frequency. There are multiple waveforms to choose from, and you can also sync the LFO to your DAW. Another thing worth noting is the Randomizer, which can either reset the displayed parameters or randomize their value to create interesting effects.

5. Phuturetone Philteroid

Turn any boring sound into something interesting with this filter plus sonic modulator combo.

Philteroid is a dual resonant filter effect that sounds fantastic, especially on rhythmic sounds, paired with its AM, FM, and saturation features. There are five types of filters: low-pass, high-pass, band-pass, notch, and all-pass. Add the modulations, and it can turn a basic sound into one with unique character and fascinating textures, in addition to pure filtering.

There isn’t a dedicated modulator to automate the filter section. However, almost every knob is automatable, so you can use your DAW’s envelopes or modulators to create impressive effects in no time. In addition, the filters are quite smooth-sounding even when paired with the input drive.

Key Features:

• Amplitube Modulation

The AM feature can act on the internal audio generated by the filters. However, you can control how much AM is applied to your audio using the envelope follower with the sidechain feature.

• Frequency Modulation

With the FM feature, filters can be synced in eleven preselected harmonic offsets in the filter frequencies and modulated internally by the generated audio. However, like with AM, you could also use external audio to apply FM. ADSR envelopes and midi-triggering are also available. Although, the midi input also acts as the FM note tracker.

• 12 inputs/outputs

There are twelve input and output ports, but they aren’t filtered. Instead, they are used for routing and modulation. It’s worth noting the filters themselves are mono.

6. Audiomodern Filterstep

Filterstep is a filter plugin designed for getting intricate rhythmic sounds.

There is a single filter in this plugin, and you can select from a high-pass, a band-pass, and a low-pass filter. The lower section is the sequencer that lets you create patterns for your filter’s frequency parameter. In contrast, the upper section lets you control the sequencer’s properties, direction, randomize the sequencer, and so on.

The first slider on the left lets you adjust the filter’s smoothness when changing the frequency with the sequencer. And the second one adjusts the range of the sequencer. Finally, the third one lets you adjust the filter’s resonance. There is a clean bypass button on the left that is automatable too.

Key Features:

• Sequencer

The lower section of the plugin is an easy-to-use sequencer where you can adjust the value of the frequency using the steps. You could also use the dice button to randomize the sequencer and get complicated sounds.

• Multi-Pattern

At the bottom of the pattern, you’ll find a row of buttons labeled presets. Each can hold a new pattern for your sequencer, so switching the rhythm style in the middle of your song is as easy as changing the pattern. Once you modify your sequencer values, just click on an empty slot, and the new sequence gets stored in that slot.

• Infinite Generation

Filterstep can create an infinite number of sequences. You can also tell it to generate a certain number of patterns and repeat itself. If you just want a textural background in your project, try using many regenerations to achieve unending texture variations.

What Does A Filter Do To Sound?

A filter manipulates the spectral quality of sound by boosting or attenuating specified frequencies. There are different types of filters, each with its specific function. However, every kind of filter certainly affects the volume/level of frequencies, usually the ones you specify.

Before we talk about the types of filters, let’s first discuss the various parts of the filters we talked about in the previous section:

• What Is A Filter Frequency?

The filter frequency is the position in the frequency spectrum where the filter acts. In some cases, however, such as in a band-pass filter, it’s where the filter doesn’t act. The illustration shows a high-pass filter, and the specified frequency is 500Hz.

• What Is Resonance In A Filter?

The resonance is also called the “Q-Factor.” It is essentially a volume gain at the filter frequency, which can be either positive or negative. It is used to control the tone of a filter to make it more or less obvious. The picture illustrates a raised resonance, which will make the sound sharper.

• What Is The Slope Of A Filter?

The slope is the distance between a filter’s active and inactive parts in a frequency spectrum. The slope is measured using decibel per octave (dB/oct). A low slope value means the spectrum will be manipulated smoothly, whereas a steep/high slope value means a harsher and more noticeable manipulation. Just like your vehicle’s speed, a higher value means a faster change from inactive to active and vice versa.

Next, let’s talk about the primary types of filters:

• What Is A High-Pass Filter?

A high-pass filter is a type of filter that allows only the sounds higher than the frequency specified to be audible while turning the lower frequencies down. It is also called a low-cut filter. It is often used on instruments other than the bass to create spectral space and lessen muddiness.

What Is A Low-Pass Filter?

A low-pass filter is a filter that removes the sounds higher than the specified frequency while letting through everything below it. Thus, it is also called a high-cut filter. It mostly finds its use to reduce harshness or create “riser” effects by automating its frequency parameter.

What Is A Band-Pass Filter?

A band-pass filter allows only the specified range of frequencies to pass through and turns the rest of the spectrum down. On such a filter, adjusting the resonance/Q-factor changes the width of the band. People often use it in conjunction with send tracks to apply effects in higher precision.

What Is A Notch Filter?

A notch or band-stop filter removes the assigned range of frequencies while leaving everything else untouched. We often use it with a high Q-factor to surgically remove hums and hisses in audio. However, using multiple instances and automating their frequency parameters is a famous technique in achieving creative synth sounds.

What Is A Low-Shelf Filter?

A low-shelf filter affects the volume of only those frequencies that are below the specified frequency. Producers often use it to boost or reduce the low end of a mix to shape the overall tone. However, you could also use it in place of a high-pass filter to make the effect milder.

What Is A High-Shelf Filter?

The filter that only affects the volume of the sounds above the frequency you specify is a high-shelf filter. Probably the most famous use it has seen is in improving audio clarity. Occasionally, though, you might employ it to subtly reduce harsh high frequencies while keeping the audio from ending up lackluster.

What is A Peaking/bell Filter?

A peaking filter is a filter that changes the volume targetting a specific frequency. The effect can be narrowed down to nearly a single frequency or kept wide and subtle. It’s better to strategically reduce the volume rather than increase it to prevent raising the noise-floor.

 

But for now, let’s have a look at the best filter plugins available today!
