What Brusfri does
Brusfri builds its noise suppression from several frequency-trimmed expanders rather than phase-altering filtering, so the desired sound is left untouched and no squishy artifacts are introduced. A learn step analyses a passage of noise, which the plugin then uses to build a noise profile, and in most cases this single step is all that is needed. Attack, threshold and release controls set all of the internal expanders together.
The interface is kept intentionally simple, with a learn button and a small set of controls. The developer describes the tool as suited to cleaning up noisy recordings while retaining sound quality, and states that it does not mess with audio phasing. The plugin is available as VST2, AU and AAX for Windows and macOS, and a trial is offered.
Key features
- Frequency-trimmed expanders. Several expanders each act on a limited frequency range, and together they form the suppressor that silences unwanted noise.
- Learn button. The learn step analyses a passage of noise to create the noise profile that the expanders then follow.
- Attack, threshold and release. Three controls set the behaviour of all internal expanders at once.
- Phase-neutral processing. The developer states that the plugin does not alter phase, which keeps the desired sound unchanged.
