Bertom Denoiser Classic v3.0.4 VST3 AU AAX WiN macOS [FREE]

Bertom Denoiser Classic is a free noise reduction effect for music production and post-production. It suits home producers and audio editors who need to reduce unwanted noise in recordings without first capturing a static noise profile. Its straightforward interface lets you adjust the processing directly, while full automation support allows settings to follow changes throughout a track.

The plugin processes audio in the time domain with zero latency, making it useful when added processing delay would disrupt your workflow. Low CPU usage also makes it practical to run multiple instances across a session. Its response depends on the incoming material rather than behaving like a conventional multiband expander.

Instead of FFT processing, Denoiser Classic uses broader frequency bands to avoid the artifacts often described as “musical noise.” There are no crossovers, and when noise reduction is inactive, the processing introduces no phase shift. Stereo linking gives you control over how the channels respond together, while HF Bias and Ratio modes provide alternative processing behavior. For producers working in Windows DAWs such as FL Studio or Ableton Live, it offers a focused tool for recording cleanup.
