i used deepfilternet commercially (my audiobook recordings use it as a final pass over the mastering) but its computationally nontrivial (its a whole neural network based filter; you could probably finagle it on to vulkan) and people said its the cleanest signal they've ever heard.
rnnoise is relatively cheap (its just basic anti-noise + the tiniest AI filter) and everywhere. kind of embarassing at this point to not have noise reduction when you can literally just import it.
