The file librnnoisevst.dll (often part of RNNoise-VST) is a real-time noise suppression plugin based on the RNNoise library developed by Xiph.Org. It uses a Recurrent Neural Network (RNN) to distinguish human speech from background noise. Performance Review
Noise Removal: Highly effective at removing static background noise such as computer fans, office hum, and air conditioning. It generally outperforms traditional noise gates because it filters noise while you are speaking, rather than just muting the mic during silence.
Audio Quality: While it is "small and fast," it can sometimes produce a "robotic" or "metallic" quality to the voice, especially if the input signal is weak or the noise is extremely loud.
Latency: Users have reported mixed results regarding delay. While the underlying library is designed for real-time use, some VST implementations may introduce noticeable latency depending on the host application (like OBS or Equalizer APO).
Resource Usage: Extremely lightweight on CPU and does not require a GPU, making it a popular alternative to hardware-heavy solutions like NVIDIA Broadcast. Critical Technical Requirements
To avoid common bugs (like no audio or heavy distortion), you must ensure your audio settings match the plugin's fixed requirements:
Sample Rate: The plugin typically only works at 48,000 Hz (48 kHz). Using other rates like 44.1 kHz often results in silence or severe distortion. Format: It generally expects 16-bit audio input. Popular Implementations
librnnoisevst.dll (often referred to as rnnoise-vst.dll rnnoise_stereo.dll
) is a real-time noise suppression plugin for voice based on the Xiph.Org RNNoise library
. It uses deep learning—specifically a Recurrent Neural Network (RNN)—to filter out background noise like computer fans, office chatter, and traffic while preserving human speech. Key Features Deep Learning Engine
: Unlike traditional noise gates that use simple volume thresholds, this plugin is trained on hours of noise and voice data to intelligently distinguish between the two. Minimalist GUI : Includes basic controls like the VAD (Voice Activity Detection) Threshold
