Free Filter Plugins & Apps

Daft Funk

Daft Funk is a free glitch and pitch shifter and filter VST plugin developed by KlangLabs. Compatible OS(s): Windows.

Daft Funk is a “Glitch accelerator”.

Features:

X-Y panel: X controls speed, Y controls LowPass Filter and volume optionally.

Mode: “Pitched” means the wave will be resampled as speed is being modulated; “Grainy” means the wave will not change pitch but the grains will change size as speed is being modulated.

Sync mode: “BPM” or “Free”.

Note subdivision selector.

Y->Vol (Y value to Volume) button.

Zero – X: Useful only in “Grainy” mode; this parameter is useful to avoid clicks, but if you want to go very fast you better untick this option, otherwise you’ll hear an artifact in where the pitch transitions aren’t smooth on very high frequencies.

X and Y spring buttons: Enable disable spring release on them.

Smooth knob: This smoothes out the X and Y values, high values result on slow response to quick movements, useful to make slow sweeps such as on one famous Daft Punk song.

Grain size knob: When in “Free” mode (opposed to BPM) you can specify the grain size here.

Crayon Filter

Crayon Filter is a free filter VST, Audio Unit plugin developed by BetabugsAudio. Compatible OS(s): Windows, macOS.

Crayon Filter is a multi-band filter plug-in. You can engage up to five filter types at once (one of each type).

Low Pass attenuates high frequencies, giving your sound a “dull” feel.

Band Pass attenuates both above and below the cutoff frequency, for a “thin” or “nasal” sound.

High Pass removes low frequency signals.

Notch removes just a small band of frequencies from the signal.

Peak boosts a small band of frequencies in your audio.

CombOver

CombOver is a free filter VST plugin developed by runagate. Compatible OS(s): Windows.

CombOver is an FSU effect based on Comb Filters. Unlike a normal comb filter effect CombOver is trying too hard to cover up the naked pate of boring audio. Unlike those old FSU fx this one is understandable, programmable and doesn’t explode with feedback. But similarly otherworldly, wet or electric, exploding or glitchy and twitching sounds are possible with CombOver.

CombOver features delay times controlled by pitch detection and harmonic overtone series slider bank modulated by a step sequencer, a vector mixing X/Y pad top select amongst the delay times of four different harmonic-modulated delay times and a harmonic mix control to blend in harmonics with the root pitch-controlled comb filter. There are five comb filters in all.

Features:

5 modulated comb filters.

Comb filter time modulation provided by input audio pitch detection.

16 graphical sliders to choose 16 harmonic overtones for modulation source.

16-step sequencer to modulate selected harmonic overtone for time modulation.

X/Y joystick-controlled vector mixer to blend between 4 harmonically-modulated comb filters.

A variety of tempo-synced beat division choices for the sequencer.

Stereo peak hold control on the pitch detector to ensure sensible pitch detection from stereo inputs, also acts as modulation smoothing envelope.

Pitch detection octave selection control.

BugPass

BugPass is a free filter VST plugin developed by BetabugsAudio. Compatible OS(s): Windows.

BugPass is a a dual-function plug-in. Its primary job is to serve as a bandpass filter, with sliders which enable a quick visual reference to the size of the frequency band being passed through. However, by reversing the slider positions, BugPass will also serve as a notch filter, eliminating frequencies between the sliders while leaving the remaining frequencies intact.http://www.betabugsaudio.com/

Brainworx bx_subfilter

Brainworx bx_subfilter is a free filter VST, VST3, Audio Unit, AAX plugin developed by Plugin Alliance. Compatible OS(s): Windows 64b, macOS.

Polishing your mix’s low end can be tricky. Bass DI tracks can sound mushy, and kick tracks can lose their “pop.” Sometimes everything below 100Hz can become such an undifferentiated soup of noise that you just don’t know where to start. Start here: The bx_subfilter is just the ticket for adding clarity and definition to tracks that have troublesome low frequencies. There are lots of expensive and complicated EQ plugins out there, but when it comes to shaping your low end, the bx_subfilter is unique for its ease and simplicity. With just a few quick adjustments to its four-knob interface, you can breathe new life into those 808s that have been muddying your mix.

The bx_subfilter is a free plugin that borrows from the “Filter” section of its larger counterpart, the bx_subsynth. It’s the perfect plugin for anyone who loves the bx_subsynth’s unique approach to low-end filtering, but doesn’t need the subharmonic synthesis. If you think that cleaning up your low end shouldn’t break the bank or require twenty knobs, we’ve got a plugin for you.

Sign up at Plugin Alliance today and you’ll get instant access to the bx_subfilter, along with our five other free plugins. No dongles, no hassles, and no payment required.

This free plugin will be added to your account automatically when you join Plugin Alliance. If you already have an account you can download and start using this plugin today.

Features:

Tight Punch knob implements a resonant high pass filter that’s especially formulated for cutting problem frequencies in bass-heavy tracks.

Resonance selector applies three peak settings to the filter – Low, High and Extreme – for accentuating punch while taming low-end rumble.

Low End control applies a post-Tight Punch fixed bandpass filter, to achieve that perfect frequency balance.

Input/output gain controls for level matching and preventing clipping.

Description

bx_cleansweep is the plugin that should go into every mix channel as the first plugin. This way you can filter out any unwanted hi-end and lo-end, and the result is a clean and tight mix.

Clever shortcuts (Alt/Shift/Ctrl) allow for detailed control over the X-axis and Y-axis of the joystick, and the EQ knobs can be set to precision mode by shift-click as well.

Features:

BRAINWORX’ critically acclaimed filter.

Fully automatable.

Dedicated BYPASS switch in the plug-in GUI.

“Mouse Over” feature: adjust the parameters by holding the mouse over any knob and simply turn your mouse wheel.
