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.

Product details

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.

*Brusfri means ”Noise free” in Swedish.

How to use Brusfri: 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.
