Hi guys, first post here! I'm trying to figure out a good way to on-set sound for a city night shoot in areas where there's still some lingering traffic noise. It was wondering if it would be possible to take a simultaneous recording of that background noise on its own, from a separate mic, and subtract that track (or a greatly gain-reduced version of it to match the intensity of the background noise on the other track) to create a clean recording. It's the sort of thing that, once I had thought of it, I was surprised I couldn't find some sort of "subtract file A's waveform from file B's," online anywhere. Is this something that exists, and if not, what about the idea wouldn't work?
Thanks! I'll probably have some other questions about trying to capture these noise-free recordings in the future hehe.
