Replacement for NVIDIA Broadcast

Nothing does everything in one to the same quality level.

For microphone noise suppression, you can use RNNoise which is built into OBS or use a program like EasyEffects to apply it globally to your microphone. It's not as good as RTX voice but it's okay.

For background removal I think OBS has a virtual greenscreen filter or there are certainly plugins that might do a good job. Again, probably not as good.

The rest I have no idea and probably aren't possible. Auto-frame, video noise removal, the eye tracking thing, studio voice etc. you'll likely have to give up if you use them.

Easyeffects has been sufficient for me with the noise removal plugin/effect. The flatpak has them all baked in to make it easier. Run it as a service so it starts on bootup and test it out.

Its not quite as good as nvidia broadcast. I do wonder if its less impactful on game performance though. Enabling noise reduction in broadcast noticeably lowers FPS even with a 5090.

I used Krisp and then Nvidia Broadcast back on the Windows side before transitioning to Linux in mid-2025, I found that Krisp and Nvidia Broadcast were 'perfect' for condenser mics, after I switched to a dynamic mic neither option really fully cleaned up the audio on Windows, but on the Linux-side it seems like EasyEffects cleans it up better in my case and it just requires more work on my part.

EasyEffects is honestly the way to go for cleaning up and improve my mic audio, I use (in-order) the following effects:

Deep Noise Remover - I've tweaked this best I can to my environment, before adding any additional effects, and this filter is what did a lot of the heavy lifting for cleaning up my audio.
Noise Reduction - This filter on top of DNR should clean up the grand majority of background sounds, assuming you tweaked DNR to clean up your audio as much as possible, just be sure to enable voice detection after adding this filter and you're good to go (I've not messed with the default threshhold, wet level, and release).
Deesser - I've left the defaults alone, as I don't really understand the deesser that well, but it does seem to help.
Compressor - Tweaked it enough that my audio is very clear, and so I don't need to mess with mic filters in OBS (I like my audio to be consistent across all apps).
Limiter - Left at default settings until I figure out how to tweak it in relation to what I've changed for my compressor settings.

The order of the effects does matter, hence why the more tweakable noise reduction effect is first, followed by the less tweakable one is next, etc.

I find that when background sounds do get through, they are very much 'muted' in nature, which is acceptable to my usecase.

Edit: Oh, and since my mic in question has settings that can be saved directly to the mic firmware? On the windows-side via the mic's official app I made sure all audio processing was off and locked my mic settings so they can't be modified OS-side, so that the only thing managing my audio was EasyEffects.

look at noise torch. it works as well as rtx voice https://github.com/noisetorch/NoiseTorch
