Matthieu Brucher has announced the release of version 1.0.1 of its ATKSideChainExpander, a free sidechain stereo expander effect plugin for Windows and Mac.
This stereo expander 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).
ATKSideChainExpander is available in VST and AU formats for Windows and Mac. Donations are much appreciated at Matthieu Brucher’s blog.
