Christian Budde Fast Compressor

Christian Budde has released Fast Compressor, a freeware soft knee compressor optimized for low CPU usage.

While it is not that difficult to build a hard knee compressor with a low CPU usage, it is quite difficult to do so for a soft knee, especially if you want to control the margin around the treshold precisely while maintaining a consistent curve. The compressor also features a simple limit circuit to avoid clipping.
On a 2 GHz core2 duo I was able to run > 60 instances without a problem.

Fast Compressor features

  • Lightweight soft knee compressor.
  • Continous and consistent characteristic.
  • Fully adjustable soft knee in dB (as margin below the threshold).
  • Stereo/dual mono processing.
  • Extra limit circuit to avoid clips.
  • Simple auto make-up gain adjustment.
  • 10 presets.
  • Mathematically optimised (using three psychoacoustical evaluated approximation functions).
  • Open source (as part of Christian’s Delphi ASIO & VST Project).

Fast Compressor is available as a VST plug-in for Windows PC.
