You can place the librnnoise_vst.dll directly into the OBS plugin directory (e.g., C:\Program Files\obs-studio\obs-plugins\64bit ).

: Unlike traditional "noise gates" that simply mute audio below a certain volume, this plugin actively identifies and filters out specific sounds like computer fans, traffic, and mechanical keyboard clicks. Efficiency librnnoisevstdll

: Dynamic Link Library, the system file format Windows uses to execute shared software routines.

The key idea behind RNNoise is to separate a human voice from background noise using a that combines traditional Digital Signal Processing (DSP) with Deep Learning. // Allocate buffers for input and output audio

Which (e.g., OBS, Reaper) are you trying to use this with? What operating system are you currently running?

RNNoise achieves approximately 80-90% of the noise reduction quality using only your CPU, with negligible system resource consumption (typically less than 10% on a modern CPU core). For users without NVIDIA hardware, RNNoise provides an accessible alternative that runs anywhere. The key idea behind RNNoise is to separate

Traditional noise suppression relies on static profiles. You capture a few seconds of silence, and the software subtracts those specific frequencies from the mix. However, this method fails when noise changes—like a car driving by or a keyboard clicking.

While the original RNNoise code can be compiled on Windows, another crucial format to understand is the . Developers have created wrapper plugins that embed the RNNoise library inside a VST interface, resulting in a single DLL file. This file is then used by a VST host application.
