ATKSideChainCompressor – VST / AU Plugin Effect ATKSideChainCompressor is a free side-chain stereo compressor VST plugin based on the Audio Toolkit. It is available on Windows and OS X (min. 10.8) in different formats. This stereo compressor can work on two channels, left/right or middle/side, possibly in linked mode (only one set of parameters), and can be set up to mix the input signal with the compressed signal (serial/parallel compression).

The supported formats are: VST2 (32bits/64bits on Windows, 64bits on OS X) VST3 (32bits/64bits on Windows, 64bits on OS X) Audio Unit (64bits, OS X) Price: Free Info & Download >> Matthieu Brucher / ATKSideChainCompressor
