ColourEQ

ColourEQ free eq by DDMF

ColourEQ is a free equalizer VST, Audio Unit, RTAS plugin developed by DDMF. Compatible OS(s): Windows, macOS.

ColourEQ is described as the first “super-parametric” equalizer. It uses a higher-order filtering scheme which leads to a qualitatively and quantitatively new frequency response. The additional degrees of freedom introduced lead to four controls per band instead of the traditional three as in standard parametric EQs.

Further features:

  • Internal 64 bit processing.
  • Free choice of colour palette in the GUI.
  • Resizable plugin window.
  • Curve display with auto-scaling.
  • Coded in proprietary C++, low CPU usage.

Classic Equalizer

Classic Equalizer free eq by IK Multimedia

Classic Equalizer is a free equalizer VST, VST3, Audio Unit, AAX plugin developed by IK Multimedia. Compatible OS(s): Windows 64b, macOS.

T-RackS Classic Equalizer consists of a high quality six-band parametric EQ, specially designed to achieve high-end performance in a mastering environment. The T-RackS Classic Equalizer consists of a high quality six-band parametric EQ, specially designed to achieve high-end performance in a mastering environment. The design of this parametric EQ filter bands allows to perform broad EQing such as giving “air” to the high end, “fullness” to the low end or “focus” to the midrange of a mix with a nice and smooth result for creative and musical applications; when needed though, given its flexibility, this processor can be used very effectively to perform very precise interventions; considering the sharpness its peaking bands can reach, it makes it easy to remove a troublesome frequency without touching the rest of the spectrum.

Classic T-RackS Equalizer can now be used in Stereo or MS modes.

The equalizer comprises the following bands:

  • 4th order High-pass filter, from 16 Hz to 5.3 kHz.
  • Low shelving type filter, from 30 Hz to 200 Hz.
  • Low-mid peaking type filter, from 33 Hz to 5.4 kHz, variable Q.
  • High-mid peaking type filter, from 200 Hz to 17.5 kHz, variable Q.
  • High shelving type filter, from 750 Hz to 8.5 kHz.
  • 4th order Low-pass filter, from 200 Hz to 18 kHz.

BugPass

BugPass free filter by BetabugsAudio

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/

BTQ2

BTQ2 free eq by J1000

BTQ2 is a free equalizer VST plugin developed by J1000. Compatible OS(s): Windows.

BTQ2 is twisting equalizer for bass and treble. Twisting works differently from usual equalization because it relatively preserves output loudness. It does that by using two interlocked pairs of shelf and peak filters – when shelf filter goes up, peak goes down, and vice versa. Some famous studio equalizers use this method to achieve deep bass and sparkling treble while simultaneously reducing muddiness and harshness. You can use it on whole mixes or on individual tracks and it will always speed up the work because it’s simple and intuitive:

  • Independent bass and treble equalization modules.
  • Each module consists of interlocked pair of shelf and peak filters.
  • Filter slope is adjusted with span control instead of standard Q factors.
  • Additional module for spectrum tilting.
  • 32-bit internal precision with zero latency and low CPU consumption.
  • No introduced harmonic or dynamic distortion, no hidden signal processing.

Brainworx bx_subfilter

Brainworx bx_subfilter free filter by Plugin Alliance

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.

Brainworx bx_cleansweep V2

Brainworx bx_cleansweep V2 free filter by Plugin Alliance

Brainworx bx_cleansweep V2 is a free filter VST, VST3, Audio Unit, RTAS, AAX plugin developed by Plugin Alliance. Compatible OS(s): Windows 64b, macOS.

FREE!

bx_cleansweep is a new Hi-Pass and Lo-Pass filter plug-in, introducing the new “Anti Crush Technology” (originally developed by Brainworx).

Analog style filter curves without the typical Nyquist problems, in a new great sounding filter design (taken from our pro mastering EQ bx_digital V2). First order filters (6 dB per octave) guarantee an extremely musically sounding filter set, and unique joystick control (taken from bx_hybrid) gives you fast and intuitive control.

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.

Ever thought about why there are Hi-Pass and Lo-Pass filter in every channel of the most expensive analog consoles (SSL, NEVE, etc.), but why most EQs are missing this feature?

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.
  • Direct access: just type in any valid number into the text fields for direct access to the exact value.
