FabFilter Pro-C is a compressor plug-in offering high-quality sound, flexible routing and side-chain options, and various program dependent compression styles with an innovative user interface and animated level display making compression easy to grasp for everyone.

Suitable for a wide range of compression purposes, Pro-C offers three compressor styles: Clean, Classic and Opto. Each style uses different custom algorithms, knee curves and compressor topologies (feedback or feed-forward), all carefully selected and fine-tuned after thorough research and development. All styles use 64-bit internal processing and guarantee zero latency throughput.

Pro-C is capable of very fast attack times and both the attack and release times are highly program dependent. Each compressor style features different forms and levels of program dependency.

Apart from its sound and character, Pro-C also offers very flexible routing options. You can choose between left/right or mid/side processing with completely customizable channel linking and routing. External side chain input is available and the detection signal can be filtered with steep 48 dB/octave low-pass and high-pass filters. Both stereo and mono versions of the plug-in are available.

Pro-C has an innovative, easy-to-use, interface. The animated level display, the active transfer curve display and the accurate input, output and gain change meters all work together to give you great insight in when, why and how compression is applied to the audio signal.

By default, the plug-in starts in non-Expert mode, which only offers the most essential compression functions. In Expert mode, the animated level display slides underneath the transfer curve display to reveal all advanced side chain options.

Like all FabFilter plug-ins, FabFilter Pro-C also offers large, fine-tuned knobs that offer quick and precise control in both vertical and circular drag modes, interactive MIDI Learn, Smart Parameter Interpolation for smooth parameter transitions, an extensive help file with interactive help hints, sample accurate automation, AltiVec and SSE optimization and much more.
