The Pro-C 2 from FabFilter is a software compressor with eight different compressor styles and program-dependent attack and release curves. It is used in mixing and mastering audio applications such as studio recording, post production, and more. It features flexible signal routing, as for example, in Expert mode, where external side chain inputs are available, providing a choice of mono, stereo, or mid-side processing with customizable channel linking and routing.

Apart from the classic compressor controls, the plug-in provides smooth lookahead, up to 4x oversampling, intelligent auto-gain and auto-release. A variable knee, hold, range, external side-chain triggering, variable stereo linking and mid/side processing, are all packed in a beautiful Retina user interface. The redesigned interface offers insightful metering and real-time displays for improved workflow, with the large animated level knee display visualizing exactly when, why, and how compression is applied to incoming audio.

Additional features include perfectly tuned knobs, interactive MIDI Learn, and an undo/redo and A/B switch. Smart Parameter Interpolation delivers smooth parameter transitions, while an extensive help file with interactive help hints, sample-accurate automation, advanced optimization and much more, extend the functionality of the plug-in.
