RNNoise noise remover

Supported Bit Versions
32-bit, 64-bit
Source Code URL
Minimum OBS Studio Version
Supported Platforms
Noise suppression plugin based on Jean-Marc Valin's RNNoise (or, more accurately, Gregor Richards's fork rnnoise-nu). Uses a recurrent neural network (fancy machine learning stuff) trained on various sets of community-submitted noise. It's fairly light on CPU usage.

You can choose between multiple noise reduction models that are tuned for slightly different use cases (e.g. "clean" recording environment vs. busy environment).

Demo video (with various types of quite aggressive noise):

It should be possible to build this on all platforms, but at this time I can only offer a pre-built version for Windows. The installer is linked in the description of the source code repository.

The plugin might work with OBS Studio 24.x and older but I have only tested it with version 25.0.8. Feedback welcome!

It cleans up noise pretty well, but when I apply it to my mic track it causes approx. 1.6-1.7 second delay (it's permanent and doesn't increase or decrease over time) for computer audio track which doesn't even have this effect applied.
Hmm, I didn't get a notification, sorry for the late response. This is definitely not normal. Unfortunately these things can be quite hard to troubleshoot and this is a hobby project I don't have that much time to spend on, so I'm kind of doubtful I can help you resolve this. Sorry!
Works as intended. Nice job!
Great stuff. I've just made a home-made studio light which uses a bench power supply and this noise filter cuts the fan noise perfectly!
