About FabFilter Pro-C 3

FabFilter Pro-C 3 is a professional compressor plug-in with very high quality sound, flexible side chain options, beautiful program-dependent compression styles, authentic analog coloration, and a stunning user interface. The Pro-C 3 app filters the microphone input and plays it back in real-time. To use Pro-C 3 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Pro-C 3 will appear in the list of Audio Unit extensions for effect plug-ins in the host app. Key features: - Fourteen different compression styles: Versatile, Smooth, Upward, TTM, Op-El and Vari-Mu in addition to the Clean, Classic, Opto, Vocal, Mastering, Bus, Punch and Pumping styles from Pro-C 2 - Polished and user-friendly interface, with (optional) animated level knee displays and accurate peak/loudness metering - Three types of realistic analog saturation, coloration and drift: Tube, Diode and Bright - Side-chain EQ section with a maximum of six bands offering many filter types and LP/HP Brickwall slopes - Program-dependent attack and release curves - Variable lookahead (up to 20 ms), which can be enabled/disabled to ensure zero-latency processing - Host tempo triggering for rhythmic compression - Intelligent Auto Gain - Auto Threshold for level-independent compressor triggering - Hold (up to 500 ms) - Custom knee, variable from hard knee to a 72 dB soft knee (to enable saturation-like effects) - Auto Release - Up to 32x oversampling - Variable stereo linking and mid/side processing, with mid-only, side-only, M > S and S > M processing - Audition Triggering option, which enables users to hear on which parts of the audio FabFilter Pro-C 2 is triggering and how much compression is being applied - Range setting, which limits the maximum applied gain change - Mix setting, which scales the gain change from 0% to 200% - Accurate, large level and gain meters, with peak and loudness level visualization (which complies with the Momentary mode of the EBU R128 / ITU-R 1770 standards) - External side-chain triggering - Optional MIDI triggering - Undo/redo and A/B comparison "Pro-C is set to become a staple of many professionals' toolkits.
