I'm working on a project, and the audio sounds very clear and crisp- except for an underlying annoying sound that was picked up on set. It was something that we didn't have control over and couldn't turn off, and it makes the audio much worse. I've been trying to use HitFilm's "Noise Reduction" feature, but I'm having trouble understanding how to use it. All it says is "Capture noise print" and "add to noise print", but I'm not sure how to capture a noise print. If anyone could help me with this, I'd greatly appreciate it
