Bertom Audio releases Denoiser Classic, a FREE noise reduction plugin for macOS, Windows, and Linux.
With this latest update of Denoiser, Bertom Audio has decided to split the plugin into two versions: Denoiser Classic and Denoiser Pro.
Both versions run with a new and improved noise reduction algorithm.
Denoiser Classic is free (pay what you like), and Denoiser Pro costs $25 and comes with a few additional features.
Noise reduction plugins don’t typically get people as excited as plugins that help you make more noise, but a good one can be invaluable, especially when it’s a freebie.
Denoiser Classic is a zero-latency noise reduction plugin with low CPU usage and a straightforward, fully-automatable workflow. The simple interface features a Threshold slider followed by six frequency band sliders where you can set the amount of reduction for each. You can adjust the frequency of each band, apply high/low-pass filters, and engage HF Bias, which means you can target problem areas with a level of precision.
Denoiser Pro offers everything the free version does, along with a new Adaptive Mode and per-band thresholds.
There are too many use cases for a plugin like this one to list, covering everything from live use to post-production, and it’s not limited to cleaning up vocals, either. It’s ideal in any situation that suffers from annoying background noise, which most of us are probably all too familiar with, unfortunately.

Sometimes, especially early in your recording career, you might think your home studio is the perfect environment for recording, then you listen back, and you have this loud hissing that makes everything sound terrible. Even when you’re more aware of it, there’s often not much you can do unless you use something like Denoiser.
Noise reduction plugins are no big secret, and there are multiple free tools, including Tonelib’s NoiseReducer, but it never fails to surprise me that so many creators still don’t use them.
I’m sure we’ve all clicked on a YouTube video because the topic interested us but switched off quickly because the sound was awful. You can find videos of people in a room full of expensive gear, discussing all things audio, with so much annoying background noise it’s hard to even laugh at the somewhat funny irony.
So, check out Denoiser if you record music, podcasts, or post live streams and don’t yet have anything to control unwanted noise. Keep in mind there is always a point of diminishing returns; slamming the reduction will remove all noise but degrade the stuff you want to keep; find the right balance.
Denoiser v3.0.0 is available in AU, VST3, and AAX formats for macOS (10.13 upwards), Windows (7 upwards), and Linux.
