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 side chain channels can be used to steer the gain stage (the same setup will be used, right/left or middle/side).

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
