xiph/rnnoise: Recurrent neural network for audio noise reduction
The librnnoisevst.dll file is a core component of the Noise Suppression for Voice plugin, a popular open-source tool based on the Xiph RNNoise library. It uses a Recurrent Neural Network (RNN) to differentiate between human speech and background noise in real-time. Performance Overview
Noise Removal: It is highly effective at eliminating stationary noises like computer fans, office hum, and air conditioning. It can also handle more aggressive, non-stationary sounds like keyboard clicks, though these are sometimes only reduced rather than fully silenced when you are speaking.
Efficiency: The plugin is designed to be lightweight and run on the CPU with minimal performance impact, making it suitable for low-power devices.
Audio Quality: While it works "wonders" for many, it can sometimes introduce robotic artifacts or a "choppy" feel, especially if the noise is extremely loud or the voice quality is poor to begin with. Key Specifications
Sampling Rate: It is strictly optimized for 48000 Hz; using other sample rates can lead to severe audio issues.
Latency: It generally offers near-zero latency, though certain advanced settings (like "Retroactive VAD Grace") can introduce minor delays.
Compatibility: Available as a VST2, VST3, AU, and LV2 plugin, it is widely used in OBS Studio and can be set up system-wide on Linux via PipeWire. Comparison to Alternatives
RTX Voice: While NVIDIA RTX Voice is often cited as more powerful due to GPU acceleration, RNNoise is a preferred cross-platform and free alternative for those without modern NVIDIA hardware.
Speex: Users often find RNNoise's suppression to be more "intelligent" and aggressive than the older Speex method, though Speex can sometimes sound more "natural" because it doesn't cut out background sounds as abruptly.
