Clean is transparent; Classic adds subtle harmonic character; Opto emulates optical compressors for natural vocals; Vocal mode is optimised for voice; Mastering provides gentle program compression; Bus mode glues a mix; Punch emphasises transients; Pumping creates the sidechain compression effect of dance music. Each style uses different algorithms and produces distinctly different results.
The built-in parametric sidechain EQ shapes which frequencies trigger the compressor. High-pass the sidechain to prevent bass from pumping the compressor. Use a narrow band to make the compressor respond only to a specific frequency — the classic de-essing technique.
FabFilter's real-time visualisation shows the gain reduction curve, input and output signal, and threshold in a clear, intuitive interface. You can see exactly what the compressor is doing at any moment.
Mixing engineers and producers who want one compressor that handles every situation. The sidechain EQ makes it particularly useful for vocals and bus compression.
The FabFilter Pro-C 2 is the most versatile compressor plugin available. Eight distinct compression styles, parametric sidechain EQ, and transparent processing make it the right tool for any compression task. At £99, among the best value plugins in any producer's arsenal.
