Courvoisier

Courvoisier free compressor by Weldroid

Courvoisier is a free compressor VST plugin developed by Weldroid. Compatible OS(s): Windows.

Courvoisier is a single-band universal dynamics processor with adaptive attack and release algorithms optimized for complex program material (mixes and submixes). Courvoisier uses free-form curves drawn over the histogram of incoming audio material (as opposed to traditional ratio and threshold parameters) to determine the transfer function of the processing.

Features:

  • Histogram representation (sliding-window statistics) of incoming program material and gain change.
  • Free-form dynamics processing defined by curves.
  • All performance-critical code optimized in assembly (utilizing SSE2 flow instructions).
  • Very low harmonic distortion (THD during normal operation is below -105 dB FS).
  • Two different program dependent attack algorithms.
  • Two release algorithms (program dependent and user defined).
  • Side chain filtering (low and high pass filters).
  • M/S operation with optional side channel transfer function.
  • Stereo operation with adjustable stereo link.
  • Dry mix option for parallel processing.
  • Peak, RMS and Hybrid level detection options.
  • Look-ahead processing for minimizing distortion with extremely fast attack settings.
  • Complex mode (oversampling with a twist).

Compressor Box

Compressor Box free compressor by Synthescience

Compressor Box is a free compressor VST plugin developed by Synthescience. Compatible OS(s): Windows.

The Compressor Box from Synthescience is our personal approach towards a fundamental studio tool. Our aim when designing it was to deliver an effective box for the duties rather than diving into obscure esoteric audiophile features.

So the path to straightforwardness is imprinted in each knob and switch in a clear and visual way to help you going without having to think too much. And to really help in your mixing/mastering duties we wrapped it with a fair set of presets tuned for diverse purposes.

The Compressor Box is fully automatable and has the ability to store 64 presets.

Installation procedure: Unzip the file, then copy the DLLs into your VstPlugins folder.

Compressive

Compressive free compressor by Martin Eastwood Audio

Compressive is a free compressor VST plugin developed by Martin Eastwood Audio. Compatible OS(s): Windows.

Compressive consists of two audio compressors written in a combination of C++ and assembly for maximum CPU efficiency.

  1. Compressive Pro is an external side chain vintage analogue modeled RMS compressor. The external side contains a 3-band EQ and mid/side controls to allow complete control of audio dynamics.
  2. Compressive Lite uses the same algorithms as Compressive Pro but has a reduced feature for minimum CPU usage.

Comp4

Comp4 free compressor by Plektron

Comp4 is a free compressor VST plugin developed by Plektron. Compatible OS(s): Windows.

Comp4 is a 4-band compressor. It can work traditionally or in side-chaining mode to boost or suppress specific frequencies. This tool allows you to manipulate the dynamics of sound on individual tracks and / or on the master channel without causing loss of quality due to the parallel compression technique.

Features:

  • 4-band compression.
  • Adjustable band frequency.
  • Internal side-chain system.
  • Soft clipping limiter.
  • Ahead delay for fast attack.
  • Pre-gain/Gain control for each band.
  • Mix control for parallel compression.
  • Analog-style meter for each band.

ComBear

ComBear free compressor by W. A. Production

ComBear is a free compressor VST, VST3, Audio Unit plugin developed by W. A. Production. Compatible OS(s): Windows 64b, macOS.

What is ComBear?

ComBear is an EXTREMELY powerful and incredibly dynamic Parallel Compression effect plugin that brings an amazing sound and feel to Drums, Synth, Vocals and anything else you can thank of! This plugin is going to change the game and sound the EDM Industry.

ComBear is packed full with incredible features like; Compress, Mix, Input Gain, Make-Up Gain and Bypass. By adjusting the Compress knob, you increase the Parallel Compression that ComBear adds the the element from value 0 to 100, Bypass ComBear’s effects on an element by flipping the Bypass switch, correct the Make-Up Gain that is altered based on how much Compress you add the the element by adjusting the Make-Up Gain, adjust how much gain comes in from the element by adjusting the Input Gain and finally adjust how much of ComBear you hear on the element with the Mix knob. The Idea behind this plugin was of course Parallel Compression.

The main way ComBear can be used is add the plugin to a certain element then have the ability to compress that element pretty hard, and then mix this harshly compressed element with a duplicate of the element that is not compressed. This tactic brings a bold, delightful and intense sound to any and all elements of the production. ComBear is a must have tool in the production world, and is something any and all producers should look into investing in.

What is Parallel Compression?

In the simplest way, Parallel Compression, also called New York Compression, is a very dynamic range compression technique that is used in sound recording and mixing. Basically, Parallel Compression is a big form of upward compression and is achieved by mixing an unprocessed “dry”, or lightly compressed signal with a heavily compressed version of the same signal. The Compress knob is what will add the Parallel Compression to the element from the value 0 to 100.

Make-Up Gain

Make-Up Gain as a whole is a make up for the gain reduction due to compression. Making sure to adjust the Make-Up Gain will bring the fullness of the compression to the sound. Do be careful not to over use the Make-Up Gain, as you can cause the plugin and the element to clip. Make-Up Gain is an amazing and useful tool inside of ComBear that we know will bring the effected element more power.

Input Gain

Input Gain is a setting that usually allows users to control the gain coming from the original element. Adjusting the Input Gain in ComBear will increase or decrease the amount of gain that comes from the original element into ComBear. If you decrease the amount of gain, then you may need to compensate this with the Make-Up Gain.

Mix

On most if not all plugins in the world, the Mix knob is a very basic feature that allows the user to judge exactly how much of the effect they want to actually be heard. ComBear’s Mix knob does the same thing, but you can also automate it to add some dynamics to the track, like bringing the effected element into the track slowly to bring in intensity.

ComBear is a plugin that will change the EDM scene forever. If you want to jump the to the top of the game, you need to get your hands on this beast. Be like the professionals and make your tracks sound top tier! W. A. Production has strived to make some of the industries highest quality sample packs as well as some of the most amazing and hard hitting plugins. We believe that ComBear is a game changer and can not WAIT for all of you to get your eager hands on this beast.

ClipStar

ClipStar free compressor by de la Mancha

ClipStar is a free compressor VST plugin developed by de la Mancha. Compatible OS(s): Windows.

ClipStar is a soft clipper effect plug-in designed to prevent peaks in a subtler way than hard clipping, increase loudness and add pleasing saturation.

Where ClipStar differs from other clippers is that it can leave the low frequencies untouched, where distortion is more evident, and allow a greater boost in gain without noticeably degrading the signal.

You can use ClipStar for peak protection, for loudness gain or for sympathetic distortion depending on your mood and the phase of the moon.

Features:

  • Vintage style soft clipper with low frequency bypass and comprehensive metering.
  • In gain & Out gain adjustable to +/- 30 dB.
  • Soft clip limit can be set from 0 to -30 dB.
  • Low frequency bypass cut off from 0 to 1000 Hz.
  • Low frequency gain can be adjusted from +/- 30 dB.
  • Subtle colouring from a home-made blend of harmonics, saturation and noise.
  • Optional hard limiting on final output.
  • Metering covers stereo input, output and gain reduction. All meters show actual and peak levels.
  • Adjustable peak meter hold time.
  • Double-click knob resets.
  • Developed with SE 1.1.
