Klevgrand Brusfri

Brusfri is a noise-reduction plugin from the Swedish boutique developer Klevgrand and has become a quiet favourite among voiceover artists, audiobook narrators, and podcasters. The workflow is dead simple: find a passage of pure room tone in your recording, click learn, and the plugin builds a fingerprint of the noise.

From there it removes that noise from the rest of the track with markedly fewer artifacts than the free or built-in de-noisers in most DAWs. The trick is that Brusfri doesn't alter audio phasing to suppress noise — instead it uses multiple fine-tuned gates to silence unwanted noise.

Voices stay natural, the air around them tightens, and you avoid the underwater warble that gives away aggressive cleanup. It runs as a VST/VST3, AU, and AAX plugin on macOS and Windows, plus as a standalone iPad app for AUv3 hosts like AUM and GarageBand iOS.

Pricing is $59.99 regular, but Klevgrand runs frequent sales that drop it to around $24 — about 59% off — making it a no-brainer at sale prices. It's a one-trick plugin: no EQ, compression, or mastering. As a clean-up specialist that lives in a chain alongside your DAW's other tools, Brusfri is hard to beat, especially during sale windows.
