It generally offers near-zero latency , though certain advanced settings (like "Retroactive VAD Grace") can introduce minor delays.
Because it targets the CPU and requires minimal computing overhead, it serves as the ultimate hardware-agnostic alternative to commercial noise-gate software and GPU-heavy tools like NVIDIA Broadcast. Technical Foundations: How RNNoise Works
Move the librnnoisevstdll file into your system's dedicated VST folder so your software can scan it. Common paths include: C:\Program Files\VSTPlugins\ C:\Program Files\Common Files\VST2\ Step 3: Scan and Load
Search your system for the file. Ensure it is placed exactly in the directory specified by your audio software's plugin paths. If it was accidentally deleted, re-download the plugin package from its official repository. 2. Plugin Fails to Scan / Crashes the DAW

Intelligently reduces transient sounds like mechanical keyboard clicking while you talk.
To use the plugin for live streaming or recording in OBS Studio: Open OBS Studio and locate the dock. It generally offers near-zero latency , though certain
: Unlike many AI-based tools, it has extremely low CPU usage, making it ideal for gamers or streamers who need performance. Real-Time Processing
: Best suited for 16-bit, mono, or stereo inputs.
A text log auto-executed:
float vad_prob = rnnoise_process_frame(st, out_frame, in_frame); // vad_prob = voice activity detection probability (0–1) often surpassing RNNoise's raw quality.
If the ambient noise is louder than your actual voice, the processor has to work too hard, causing digital artifacts. Try to get your microphone physically closer to your mouth to improve the signal-to-noise ratio. The Verdict
NVIDIA Broadcast uses GPU-accelerated AI models that can produce studio-quality noise removal, often surpassing RNNoise's raw quality. However, Broadcast requires a compatible NVIDIA GPU and typically consumes 2-3 GB of VRAM while active.
The plugin analyzes the incoming audio stream, breaking it down into specific frequency bands.
If your application (like OBS or a VST host) complains that librnnoisevst.dll is missing or not found, it usually means the plugin was improperly installed or removed. How to Install/Fix librnnoisevst.dll
