I don’t think YouTube normalizes the audio on their videos. I have no idea why, but that could easily become a quiet video that leads into a -16 LUFS ad that blows your ears out.

Supposedly they'll turn it down if it's mastered louder than -14 LUFS. They won't turn it up if it's quieter.

I couldn't find a Youtube source for this but it's mentioned extensively online: https://audio.rswaver.com/blog/youtube-loudness-standards

They have a "stable volume" toggle, actually. I don't see ads, so I don't know whether it works for those.

		They do, but as usual with those, it wrecks all the decently mixed videos by making everything the same volume. Though as those are rare as hen’s teeth, perhaps you might as well.
