An advanced audio noise reducer with a simple and straight-forward interface.

Floor the noise.

Brusfri is a highly advanced audio noise reducer, packed into a simple and straight-forward interface. It is very well suited for cleaning up noisy audio recordings, while retaining sound quality. Unlike many other noise reducers on the market, Brusfri doesn’t mess with audio phasing to suppress noise (a technique that often comes with audible side effects). Instead, multiple fine-tuned gates are used to silence unwanted noise.


Select and hold LEARN for a second, during input of the unwanted noise, to create a noise profile. Make sure to only feed the reducer with isolated noise when it’s learning what is noise, since it will use it to suppress the noise. Most of the time, using LEARN is all that is needed, but there is also a handful of parameters to fine-tune the reduction.

  • Several frequency-trimmed expanders build an intelligent noise suppressor
  • No phase-altering, which leaves the desired sound untouched (no squishy artifacts as in many other noise reducers)
  • Intuitive and unique user interface

  • 1. Learn button

    Brusfri needs some noise to be analysed. Most of the time, this is the only thing that's needed. Push and hold to feed audio data and create a noise profile.

  • 2. Attack-Threshold-Release

    These parameters controls all the internal expanders relatively.

  • 3. Tonality

    Most of the time, Brusfri does a good job in creating a noise profile that works as expected, but in some cases (especially when there's heavy noise involved) one needs to tweak a bit.
