Steady background noise is where it shines: room tone, air conditioning, computer fans, street hum, and keyboard clicks. It separates speech from everything else rather than just filtering frequencies.

Remove background noise isolates the voice from everything else. Level the volume evens out loud and quiet sections so the whole recording sits at a consistent, comfortable level. Use both for the best result.

No. The cleaned track is pinned to the same duration as the file you uploaded, so it still lines up with anything you cut it against - a video, a transcript or a set of chapter markers.

Noise removal is built around separating a human voice from background sound, so it works best on speech. On music or ambient audio, use volume levelling on its own.

Use the Video Audio Cleanup tool instead - it runs the same cleanup and hands the video back with the picture untouched.
