Understanding librnnoise_vst.dll : The Essential VST Plugin for Real-Time Noise Suppression

In OBS, go to the Audio Mixer , click the three dots ( ... ) next to your microphone, and select Filters . Add Plugin: Click the + button and select VST 2.x Plug-in .

Instead of aggressively cutting frequencies, the algorithm applies a dynamic "mask" that smoothly attenuates non-speech elements while leaving human vocal frequencies completely untouched.

If you have ever recorded a podcast, streamed a game, or hopped on a Zoom call from a less-than-perfect environment, you know the struggle. The hum of an air conditioner, the rattle of a mechanical keyboard, or the distant barking of a dog can ruin an otherwise perfect take.

RNNoise's key advantages include:

Once loaded, you’ll see a few key settings that make a world of difference:

int main() // 1. Create a denoising state DenoiseState *st = rnnoise_create(NULL);

librnnoisevst.dll (often referred to as rnnoise-vst.dll rnnoise_stereo.dll

: Use rnnoise-stereo.dll if you are working with stereo sources, but most microphone setups perform better with the mono-focused version to avoid "one-ear" audio issues. librnnoisevstdll

To use RNNoise as a VST (Virtual Studio Technology) plugin on Windows, you will typically need the Werman implementation which provides the easy-to-use DLL files.

In short, It acts as a bridge, allowing you to load the powerful RNNoise engine directly into your audio software as a plugin.

At its core, librnnoisevstdll is a bridge. While the foundational RNNoise library is written in raw C code intended for developers, the VST .dll wrapper allows everyday users to apply it as an audio plugin.

librnnoisevstdll is just the delivery mechanism. The real hero is , a library developed by Jean-Marc Valin (originally at Xiph.Org). Unlike traditional noise gates that simply mute sound below a threshold, RNNoise uses a Recurrent Neural Network (RNN) — a type of deep learning model — to distinguish between human speech and background noise in real-time.
