other than the compressor the other comment mentioned, having a proper AV with multiple channels can also help with a lot of media, at least stuff that was mastered properly. Usually the center speaker carries mostly the dialogue and not much else, so I boost it like 7-8dB, this works pretty well for most things on Netflix and co, but Stereo (no center channel to boost) and shitty mastering (too much noise in center channel) still have the same issues
