Compatible with AUv3 host apps such as Logic Pro, GarageBand, Cubasis, AUM, Auria and n-Track Pro.
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.
