NVIDIA Maxine denoiser virtual microphone

Dangerous permissions Verified creator MIT v1.0.0

About

HUSH runs NVIDIA's Maxine Audio Effects denoiser on your GPU in real time and exposes the cleaned signal as a virtual PipeWire microphone you can select in any app. A parametric band section removes mains hum and other tonal noise. The NVIDIA Maxine runtime and per-GPU models are downloaded on first launch (they are not bundled). An NVIDIA GPU (Turing / RTX 20-series or newer) is required. Not affiliated with, sponsored by, or endorsed by NVIDIA.
