Brusfri

The deal

$24 at Plugin Boutique (down from $59.99). Sale ends April 26, 2026.

What it is

Brusfri is an audio noise reduction plugin by Klevgrand. It uses multiple frequency-trimmed expanders to build an intelligent noise suppressor that silences unwanted background noise without altering phase - meaning no squishy artifacts or audio degradation. You feed it a noise profile using the Learn button, and it takes care of the rest.

Who it's for

Producers, podcasters, voiceover artists, and engineers who deal with noisy recordings - whether that's HVAC hiss, room noise, mic self-noise, or any constant background interference that crept into an otherwise solid take.

Key features

• Several frequency-trimmed expanders work together to build an intelligent noise profile
• No phase-altering means your desired audio stays untouched with no artifacts
• The Learn button makes noise profiling fast - hold it during a noisy section and you're done
• Supports AU, VST-2, VST-3, and AAX on both macOS (M1 optimized) and Windows
