Brusfri: Audio Noise Reducer Plugin by Klevgrand Free Download

Many noise reducers suppress noise by changing the phase of the audio, which can leave squishy or smeared artifacts on the sound you want to keep. Klevgrand says Brusfri avoids this by using several frequency-trimmed expanders that work together as an intelligent noise suppressor. The plugin silences unwanted noise through these fine-tuned gates, so the underlying performance stays closer to its original character.

The main controls are Attack, Threshold and Release, which set the behavior of all the internal expanders relative to one another. This keeps the adjustment process compact, even though the processing underneath is layered.

Brusfri works from a noise profile. The Learn button analyzes a section of noise: push and hold it while the noise plays to feed audio data into the plugin. According to Klevgrand, this is usually all that is needed to build a profile that works as expected.

When the noise is heavy, the Tonality control gives you a way to adjust the profile further. It is the setting to reach for when the first pass leaves too much noise or affects the material more than you want.
