RNNoise achieves near-magical levels of noise reduction thanks to its hybrid design. Let's look at what's happening under the hood when you speak through a microphone equipped with RNNoise:
Below is a complete implementation example showing how to integrate librnnoisevstdll into a Windows C++ application. This example assumes the DLL is present in your executable directory.
The plugin introduces minimal latency (roughly 20ms at 48kHz), though some host configurations or specific "Retroactive VAD" settings can increase this delay. Key Strengths and Limitations
librnnoisevst.dll is the core dynamic-link library file for , a high-performance, open-source noise suppression plugin designed for real-time voice applications. Based on a recurrent neural network, this technology offers superior background noise removal without the traditional artifacts associated with older noise-gate technologies. What is librnnoisevst.dll ?
RNNoise tends to be more conservative, preserving speech quality even in challenging conditions where aggressive algorithms might cut out parts of your voice. If you've ever used Discord and noticed your voice "cutting out" mid-sentence, RNNoise is less likely to cause this issue than more aggressive algorithms.
Here is a comprehensive guide covering what it is, how it works, and how to use it.
: Designed to be small and fast enough to run on low-power devices like a Raspberry Pi without needing an expensive GPU.

Unlike massive AI models that require high-end Nvidia graphics cards (such as RTX Voice), RNNoise was optimized to run efficiently on standard computer processors. It uses a fraction of a single CPU core's power. 3. Set-and-Forget Simplicity
