ATKSideChainCompressor
ATKSideChainCompressor is a free compressor VST, VST3, Audio Unit plugin developed by Matthieu Brucher. Compatible OS(s): Windows 64b, macOS.
ATKSideChainCompressor is a stereo compressor with a side chain stereo input.
It can work in left/right or middle/side mode or in linked mode, allowing channels to be steered by a mix of power coming from each channel, each passing through its own attack-release filter. It enables more creative workflows with makeup gain specific to each channel.
The compressors have color section on top of the usual controls, with an optional Middle/Side processing as well as side-chain working either on each channel separately or in middle/side as well.

ATKAutoSwell
ATKAutoSwell is a free compressor VST, VST3, Audio Unit plugin developed by Matthieu Brucher. Compatible OS(s): Windows 64b, macOS.
ATKAutoSwell works like a compressor, but instead of only acting on the signal above the threshold, it applies the gain transfer function to the full signal. So above the threshold, you can lower the output signal.

Arsenal Compressor LE
Arsenal Compressor LE is a free compressor VST plugin developed by Ourafilmes. Compatible OS(s): Windows.
This plugin is a complete vintage compressor with internal side-chain filters and M/S (Mid/Side) processing. This free LE version does not feature the Threshold and Mix knobs or their functions: it has a fixed threshold (-25 dB) and its set as 100% wet effect (you can’t blend it with the original signal). Use it to process any sound that needs dynamic processing. Use the side-chain feature to process only certain frequencies, leaving the other frequencies unprocessed. And last but not least, with the M/S feature, you can process dynamically only the Mid, the Sides or even achieve parallel compression (50/50) but in M/S.
This is a 32-bit VST plugin and it is a limited version of the Arsenal Compressor plugin, only available in our FX and Total Packs.
Full automation, MIDI learn (right-click knobs), zero latency.
Check the video to see how it works.

as_fbComp
as_fbComp is a free compressor VST plugin developed by Anton Savov. Compatible OS(s): Windows.
as_fbComp is a Feedback Compressor/Limiter.
The plug-in uses 2 input and 2 output channels.
There are two modes of operation:
- Mono – the detector uses L and R input channels, but only the L channel is sent out as audio (R input is used as side-chain input).
- Stereo – the detector uses L and R input channels, and they are both processed with gain reduction and sent out (gain reduction is the same for both).
This compressor is not transparent. It has DC-removing filters on the inputs and outputs, and the outputs pass through a slightly non-symmetrical soft-shaper, which also hard-clips to 0dB.
Main controls:
- Threshold.
- Input (pre-amplification).
- Attack.
- Release.
- Output (post-amplification).
- Dry.
Side-chain controls:
- Source (balance between L and R for the detector, only works in Mono mode).
- Low shelf Gain.
- Low shelf Cutoff.
The compressor works at 4x oversampling. There is a latency of 2 or 3 samples which is not reported to the Host.

Amplitude Imposer
Amplitude Imposer is a free compressor VST plugin developed by ndc Plugs. Compatible OS(s): Windows, macOS.
Amplitude Imposer takes two stereo inputs, and imposes the amplitude envelope of the first one onto the second. It also has a feature where you can set a threshold level, and whenever the second signal’s amplitude falls below it, it is automatically amplified up to the threshold, in order to give a more constant signal to the amplitude imposer part.
It’s kind of like a compressor, but backwards.
