NVIDIA Broadcast

NVIDIA Broadcast uses AI models running on RTX graphics cards to remove background noise and echo in real time, plus offers webcam effects like background removal and eye contact correction, aimed at streamers and video callers.

For video podcasters who already own a gaming PC with a compatible card, it's a genuinely free way to clean up microphone noise live during recording, no plugin purchase required.

The hardware requirement is a hard wall, this isn't a cross platform tool, it's specific to NVIDIA's RTX line, so Mac users and anyone with older or non NVIDIA graphics cards can't use it at all.

Worth enabling as a free supplement if you qualify, but it shouldn't be your only noise strategy, since results vary with how loud and constant the background noise actually is.
