PSP Impressor

PSP Impressor is a high-precision compressor plugin built for mixing and mastering. It recreates the character of classic valve and opto-electronic compressors alongside modern designs, giving you flexible dynamics control on individual tracks, buses, or full mixes. Its configurable sidechain filter shapes how compression reacts, letting you use it as a de-esser or tame kick-drum pumping. Choose peak or RMS detection and a range of soft-knee curves to dial in anything from gentle glue to assertive control. The output stage works as a brickwall limiter or soft saturation, protecting peaks above 0dBFS. For a cohesive analog-style finish, pair it with PSP Saturator—before or after—using subtle settings. It suits hobby producers and mixers who want versatile, musical compression for FL Studio, Ableton, or Logic.
