Matthieu Brucher has updated its Audio Toolkit based side-chain stereo compressor and expander effect plugins.

Matthieu Brucher ATKSideChainCompressor & ATKSideChainExpander

These stereo plugins 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), depending on the switch on the top right of the plugins. The same coloration stage than ATKColoredCompressor and ATKColoredExpander are used here.

This effectively makes ATKStereoCompressor obsolete, as the compressor can be set up in the same conditions as ATKStereoCompressor.

These new versions have more parameters than the previous ones, which means that the parameters used in a project with the former version won’t be loaded in the same way for these new versions.

The plugins are available for download for Windows and Mac (VST/AU).
