Mira’s blood went cold. She was about to disconnect when the sandbox’s audio meter spiked. A whisper crawled out of her laptop’s tiny speaker, layered beneath white static:

The plugin is strictly optimized for 48000 Hz (48kHz) audio. Using other sample rates can lead to poor performance or the plugin failing to function correctly.

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 .

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.

How to investigate (step-by-step)

Choose librnnoise_vst.dll from the dropdown menu.

Download the latest release of the plugin, which will include the librnnoise_vst.dll file. Install VST:

#include "rnnoise.h"

// 3. Destroy the state to free resources rnnoise_destroy(st); return 0; librnnoisevstdll

It suppresses a wide range of noises, including PC fans, office chatter, aircraft engines, car noise, and construction.

High-quality audio capture has transitioned from a specialized studio luxury to an everyday necessity. Whether you are live-streaming on OBS Studio , participating in remote work meetings, or recording clean podcasts, background sound is a persistent enemy. Keyboard clicks, computer fans, and air conditioners quickly degrade speech clarity.

rnnoise_get_frame_size() is your essential helper for buffer allocation. For 48 kHz audio, each frame contains exactly 480 samples, representing 10ms of audio. You must feed frames of exactly this size into rnnoise_process_frame() for correct processing. Mira’s blood went cold

Effectively eliminates consistent low-frequency hums.

Built heavily upon the prominent werman/noise-suppression-for-voice GitHub repository , this file enables real-time, AI-driven background noise cancellation across various audio platforms on Windows. Content creators, livestreamers, and remote workers rely on it to strip out room echoes, keyboard clicks, and fan noises without needing a proprietary Nvidia RTX graphics card. The Core Technology Behind RNNoise

At the heart of this library is (Recurrent Neural Network Noise Suppression), an open-source project from the Xiph.Org Foundation known for the Opus audio codec. It is a noise suppression library based on a recurrent neural network.

It is derived from the Xiph's RNNoise project and is often associated with the werman/noise-suppression-for-voice GitHub project, which packages the RNNoise technology into a VST plugin. Using other sample rates can lead to poor
