W1 Limiter

W1 Limiter free limiter by 4Front Technologies

W1 Limiter is a free limiter VST, VST3, Audio Unit, RTAS plugin developed by 4Front Technologies. Compatible OS(s): Windows 64b, macOS.

W1 Limiter is a “brickwall limiter” that is a clone of Waves L1-Ultramaximizer, with “identical output” and an approximation of Waves L2.

Waves’ L1 (and thus W1 – for compatibility reasons) uses three times longer actual release time than the standard RT60 metric. This means that if you set 50ms release in the limiter, it will actually yield with 150ms standard RT60 release time, but users of L1 should be familiar with it.

Starting from version 2.0 W1 Limiter also contains adaptive release logic. The author tried to emulate Waves L2, however could only do this approximately. Also, unlike Waves, W1 allows changing release time while in adaptive mode.

Waves IDR dithering is not emulated.

VSTplug governor

VSTplug governor free utility by King Oz Records

VSTplug governor is a free audio and studio utility VST plugin developed by King Oz Records. Compatible OS(s): Windows.

The VSTplug governor is a basic solution for mastering to meet -6 dbfs standards. It’s a new release and though there is no known issues, it should meet your expectations in regards to being able to mix down to a certain level.

Though it’s not entirely accurate in the way of knobs, without adding lufs c-weighting and such it’s hard to do. But it works. I hope that’s good enough. I plan to attempt to add c-weighting for the dB level, My fear is that it will not be real time, and there will be 20, 30 ms latency.

Perhaps as an option it would be best.

Please keep in mind this a prototype that was made to test a theory. And I think that’s important for a developer to do. I stick My head out once in a while to make something cutting edge and I’m glad that this product for the most part came out fairly well. I think there’s a big room for change in this product but it is an interesting idea.


Version 1
+ initial release.

Version 1.1
+ fixed 64-bit gain, oversampling bug.

Version 1.2

planned changes

Vanilla Compressor

ZynAddSubFX free software-synthesizer by paulnasca 2

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

The Vanilla Compressor is a general-purpose, stereo compressor plugin, with optional sidechain input. It can be used on individual instruments, across aux busses, or even as a mastering effect. Its fine-tuned, “smooth as buttah” sidechain and specialized release shapes make it equally at home with vocals, drums, guitars and full mixes. Use it sparingly for subtle, transparent “tightening”; or drive it hard and fast for deep, “balls-to-the-walls” pumping.

The Vanilla Compressor is currently in the alpha stage, and is free to download and evaluate. After development is completed, the final release will be available for purchase for US$50.


  • Threshold: -40dB to 0dB in 0.1dB increments.
  • Ratio: 1:1 (no compression) to 20:1 (limiting).
  • Soft-knee: 0dB (linear/”hard knee”) to 12dB (nonlinear/”soft knee”) in 0.5dB steps.
  • Max Make-up: Maximizes the output gain to 0dB, such that it is proportional to the threshold and ratio parameters.
  • Compressor Output: -40dB to +40dB in 0.1dB increments.
  • Attack.
  • Release.
  • Release Shape: Smooth, Pump, ARC-1 & ARC-2 (Auto Release Control).
  • Key Input (for sidechain).
  • Detection: Peak and RMS.
  • SideChain Filter: Let the compressor react to certain frequencies, while ignoring others. Off, Low, High and Band settings.
  • Frequency: Cutoff frequency for the sidechain filter (60Hz to 6kHz).
  • Listen: Listen to the sidechain (control) signal at the output of the filter, before it is rectified/averaged.
  • Mix: Wet/Dry mix.
  • Output: -40dB to +40dB in 0.1dB increments.
  • Limiter.

The Vanilla Compressor uses RMS power summing for stereo linking, to maintain an accurate image of stereo signals.
