Pumper 3: Multi-Effect Dynamics Plugin by W. A. Production Free Download

The compressor offers four modes. Punchy is aimed at direct punch and clarity, suited to kick drums and percussion. Fat emphasizes the bottom end. Clean is more transparent and is intended for cohesion on softer vocals or acoustic instruments. Soft applies subtle compression for a tighter master bus.

Pumper 3 adds adjustable wet/dry parallel compression and RMS shaping controls, so parallel compression can be set up inside the plugin rather than with separate channel routing.

The saturator ranges from subtle warmth to pronounced distortion with a harder edge. Rise and Fall controls shape transients and smooth the character of the saturation. The stereo imager adds width and depth, and its dedicated low and high shelf modes, with frequency and resonance controls, let you focus width processing on specific frequency ranges.

Each module has its own input control for balancing the effects, and per-module and master gain controls help keep levels in check. The real-time waveform window shows the audio before and after processing, which helps with A/B comparison.

The 50 factory presets are accessible from the plugin menu and serve as starting points for the instrument or bus they are named for. You can also save your own settings as user presets. The interface is resizable, and the included PDF manual and tutorial video cover the controls.
