Free EQ & Filter Plugins

Bark of Dog

Bark of Dog is a free equalizer VST, VST3, Audio Unit, RTAS, AAX plugin developed by Boz Digital Labs. Compatible OS(s): Windows 64b, macOS.

Bark of Dog is a bass resonance filter that lets you increase your low end without turning up the flab. I like to think of it as a way to boost the low end while still keeping it under control. While the controls are super simple, the effect that this has on controlling the low end in a mix is pretty exciting.

Is this just a resonant high pass filter?

Yes, it is.

Why create a dedicated plugin for a tool we all already have?

Great question. Truthfully, what you get here can be accomplished with pretty much any digital EQ plugin. The reason why I made a dedicated plugin for this is because even though I had the capability to put a resonant high pass filter on my tracks for the past 15 years using my stock EQ, the thought never occurred to me to try it. I read reviews on a certain plugin that claimed to enhance the low end with a resonant high pass filter, and everybody who tried it seemed to love it. Rather than spending loads of money on a big dongle and then more money on a plugin, I decided just to make my own.

Even though it is super simple, I think it lived up to it’s hype. I love this tool. It solved all my low end problems. Because this is a feature we all already have, I didn’t feel right about charging money for it. There are enough good new ideas to do that I don’t want to fall into the trap of repackaging old tricks. Think of this as more of a really helpful tip with a plugin to go along with it. If you don’t want to download this plugin, then at least open up your stock EQ and play with the resonance on your high pass filter. It made my life a lot easier, and I think it can make yours easier too.

Atom

Atom is a free filter Audio Unit plugin developed by Sinevibes. Compatible OS(s): macOS.

Atom is a filter with focus on dynamic, tempo-synchronised modulation. It features five different resonant filter types each with three slope settings – up to super-steep -48 dB/octave. But what makes it special is its two modulators which feature multiple waveforms and run at rates from 1/128 note to 16 bars. Thanks to the chaos function which randomises the amplitude of each modulator cycle, as well as lag switch that smooths the waveform curves, Atom allows you to easily create lively, elaborate filter effects that work perfectly for pretty much any kind of input source.

Atom is also the first Sinevibes plugin to feature a new interface design language that cleanly presents internal components and logical or audio connections between them. With immediate response and no menus to get lost in, Atom is a simple yet delightful tool that you will surely use a lot.

Specifications:

Multi-mode filter with five types and –12/24/48 dB/octave slope steepness.

Dual modulators with eight waveforms, per-cycle chaos function and shape lag on/off switch.

Advanced transport sync algorithm with support for tempo and time signature automation.

Extensive use of OS X Core Animation and Accelerate frameworks for hardware-accelerated graphics and audio processing.

Argotlunar

Argotlunar is a free multi fx and echo and delay and filter and pitch shifter and time stretcher and granulizer VST, Audio Unit plugin developed by Michael Ourednik. Compatible OS(s): Windows 64b, macOS.

Argotlunar is a real-time delay-line granulator. It breaks up an incoming audio stream into short samples (Grains). Each grain can have random settings of amplitude, panning, duration, delay, pitch, glissando, filter and envelope. The output of all grains is mixed and sent to the main output. The main output can be fed back into the main input.

Most of the parameters can be correlated. Examples: Higher filter cutoff for grains with higher pitch, and vice versa. Grains with shorter duration can be panned to the center, and conversely the grains with longer duration can be panned wide in the stereo field.

Details:

Time-related parameters can be synced to the host tempo.

Pitch-related parameters can be quantized to various chords/scales.

Up to three pairs of parameters can be correlated.

Raised-cosine-bell, parabolic, and triangle grain envelopes, with adjustable shape.

Transposition is spline-interpolated to reduce aliasing.

12dB state variable filter (HP/BP/LP/Notch).

Comb filter.

Anticode

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

Anticode is a filtering / mangling effect plug-in; it follows the same basic idea as mWarped Linear Prediction Filter, but this time the filter can have a higher order, the residual signal after whitening can be shifted faster or slower, saturated or decimated. Furthermore, most parameters can be made targets of two LFOs and the envelope follower, in addition to which the output is fed back through a delay line and analyzed along with the input.

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

AntiAlias filters out frequencies above the Nyquist frequency by oversampling then shelf filtering with a FIR filter.

Features:

Stereo Input and Output.

32-bit Floating Point Audio Engine.

Amplio

Amplio is a free equalizer VST plugin developed by VST Zone. Compatible OS(s): Windows.

Amplio is a way to enhance boring and dull sound. It’s a 3 band Equalizer with adjustable bands and additional multiband effect modules. The plug-in is originally designed to enhance drum patterns but it is powerful enough to be used on any type of sound. Reverb effect routable to any of three bands will add more space to mix and Soft Limiter will prevent any clipping on final output.

Version 2 changes:

New multiband Noise gate with envelope controls will help you totally change your beat and create something new.

Total overhaul of user interface, faster load and smaller file-size. Improved controls. You can now use right mouse click to set default values and double right mouse click to set value to zero on all controls. Holding shift while dragging will increase sensitivity for better value settings.

No more overlapping band control points on Frequency splitter.

Improved Reverb and fixed wet/dry mix.

Low band saturation now working correctly.

Improved soft limiter to work better with distortion module.

Control the stereo field with new multiband stereo balance module. Handy gadget for centering bass frequencies.

Assembly optimization of all modules in order to save as much cycles as possible. Even with new noise gate CPU usage is same or even better than in previous version.

Adjusted all existing presets and added new 14 new presets. Total 66 presets including Amplio presets that use Distortion module.

Version 1.1 changes:

additional optimization (up to 12% CPU usage reduction).

added knob readout for reverb module.

new distort module (see the attached audio demo).
