> I wish VLC had a better loudness processor, I don’t succeed to configure it to keep the whole movie at the same volume, whether they’re speaking or using automatic guns.

Probably won’t help you if you’re using VLC, but most of the streaming services now have multiple audio tracks in the same menu that would switch to another language called “<Language> - Reduce loud noises” which is pretty much that. I just find it inconvenient as an apartment dweller that the default is to blast the volume during any action sequence.
