Krisp is a commercial noise suppression application that runs as a system-level virtual audio device. Krisp generally offers more aggressive noise suppression than RNNoise, but this can occasionally lead to speech being mistaken for noise and muted mid-word.

Traditional noise reduction filters rely heavily on a "noise gate" or fixed frequency subtraction. A noise gate cuts off audio completely when you stop talking, but the moment you speak, the background hum or fan noise bleeds right back through.
If your DAW or OBS cannot find the plugin, double-check that you placed the DLL in a folder scanned by the software. You may need to trigger a manual "Rescan Plugins" option within your software's preferences. librnnoisevstdll
: A recurrent neural network, trained on thousands of hours of clean voice and noise samples, evaluates the audio.
It is strictly optimized for 48000 Hz ; using other sample rates can lead to severe audio issues.
Place it in your standard VST plugin folder (e.g., C:\Program Files\VSTPlugins ) for use in DAWs like Audacity or Audition. Krisp is a commercial noise suppression application that

Understanding librnnoise_vst.dll: The Ultimate Open-Source AI Noise Suppression Solution
The most popular way to use the RNNoise VST plugin is with (Audio Processing Object), a powerful, free system-wide equalizer for Windows that can load VST plugins. This method applies noise suppression to your microphone at the system level, benefiting every application—Discord, Zoom, OBS, and more.
Compiling or downloading RNNoise as a standalone VST plugin ( librnnoisevstdll or rnnoise_stereo.dll ) allows the tool to run inside any Windows host that accepts VST2 or VST3 structures. This opens up the ability to route clean, noise-canceled audio directly into Discord, Zoom, Microsoft Teams, Skype, or digital audio workstations (DAWs) like Audacity and Reaper.

Some OBS users report that enabling the physical mute button on their microphone while RNNoise is active can cause render time spikes and frame drops—a known issue worth monitoring if you frequently mute your mic during streams.
