Librnnoise-vst.dll
librnnoise-vst.dll is a lightweight, highly effective tool for real-time audio cleanup. It bridges the gap between high-end AI audio processing and consumer software, providing "broadcast quality" noise suppression without the CPU overhead of heavier commercial alternatives like iZotope RX or NVIDIA Broadcast.
The file librnnoise-vst.dll is a core component of the RNNoise VST plugin, an AI-powered tool used for real-time background noise suppression. It is highly popular among streamers and remote workers for cleaning up microphone audio in software like OBS Studio, Discord, or Equalizer APO. What it Does
Unlike traditional noise gates that simply mute audio below a certain volume, this DLL uses a Recurrent Neural Network (RNN).
Targeted Suppression: Specifically trained to filter out common "non-voice" noises like computer fans, mechanical keyboards, traffic, and office chatter.
Voice Preservation: Aimed at keeping human speech clear while aggressively cutting other frequencies, though it can occasionally distort singing or laughing as "noise".
Minimal Latency: Designed for real-time use, meaning there is very little delay between you speaking and the processed audio reaching your listeners. How to Use It Noise suppression plugin based on Xiph's RNNoise - GitHub
The file librnnoise-vst.dll is a VST plugin used for real-time background noise suppression. It is based on Xiph’s RNNoise library, which uses a deep learning neural network to filter out unwanted sounds like computer fans, typing, and traffic while keeping your voice clear. 🛠️ Installation & Setup
To use this plugin, you must have a "VST Host" (software that can run VST files). Common hosts include OBS Studio, Equalizer APO, or digital audio workstations (DAWs).
Download the Library: Get the latest version from the Noise Suppression for Voice GitHub.
Move the File: Copy librnnoise-vst.dll to your standard VST plugin folder: C:\Program Files\Common Files\VST2 (Standard 64-bit) C:\Program Files (x86)\Common Files\VST2 (Standard 32-bit)
Configure Sample Rate: Ensure your microphone and system audio are set to 48,000 Hz (48kHz). The plugin is specifically trained for this rate and may not work correctly at others. 🎤 Use Cases
OBS Studio: Add it as a "VST 2.x Plug-in" filter on your microphone source to clean up live streams.
Equalizer APO: Use it to apply noise cancellation to your microphone system-wide (for Discord, Zoom, or Teams).
Video Editing: Add the plugin to tracks in Kdenlive or other editors to remove noise from recorded clips. ⚙️ Key Settings
If the plugin has a user interface (UI), you can adjust these parameters to fine-tune performance:
VAD (Voice Activity Detection) Threshold: Adjusts how "sure" the AI must be that you are speaking before it lets sound through. Usually, 85% to 95% works best. librnnoise-vst.dll
Grace Period: Controls how long the filter stays "open" after you stop talking. Increasing this prevents the ends of words from being cut off.
Retroactive VAD: Helps catch the very beginning of your speech, but adding too much will introduce latency (delay). ⚠️ Important Considerations Noise suppression plugin based on Xiph's RNNoise - GitHub
librnnoise-vst.dll is the Windows version of the RNNoise real-time noise suppression plugin, originally developed by Xiph.Org and ported for VST use by werman on GitHub.
