Free Noise Reduction Software For Windows

free-noise-reduction-softwareFree Music Software: Christian Budde’s Noise Reduction is a free VST plugin for Windows.

Budde notes:

The Noise Reduction plugin is based on a spectral gate to filter out unwanted noise in the frequency domain. The gate is based on the lightweight dynamic series and features a soft knee and customizable attack and release times.

Originally this plugin was planned for the KVR’09 developer contest, but in the end I missed the deadline by one day and thus I had to use another plugin for my entry.


  • Highly customisable spectral noise gate
  • Continous and consistent characteristic
  • Fully adjustable soft knee in dB (as margin below the threshold)
  • Several exotic window functions available
  • Low CPU usage
  • Different FFT sizes
  • Manual included
  • Open source (as part of the Delphi ASIO & VST Project)

Download it from Budde’s site.
