    Large dynamic range is a good thing, in audio and video. There are a number of ways to reduce dynamic range, if you really need to. Expanding dynamic range after capture is possible, too, but more fraught.

    Shannon information theory gives us ways to perfectly reconstruct the lower range version from an expanded range version, but it also guarantees that reconstructing the higher range version from a reduced range version cannot be perfectly accurate across all inputs. (Assuming a fixed output range capability.)

      Large dynamic range is a good thing, in audio and video.

      a good thing for accurately reproducing the original signal.

      But many people watching a show at home would like to just watch the damn movie without anything being particularly loud or resorting to subtitles. Decent range compression achieves that. Applying information theory to a Sunday night movie is stupid.

      I’m also here to support dynamic range. I don’t want the volume “normalized”, I want loud louds and quiet quiets.

        A lot of people live in apartments or have kids. While I enjoy being able to listen to loud explosions and quiet whispers, it can make movie watching experiences miserable.

              You’ve gotta compromise somewhere dude. Sound quality, neighbors’ opinions of you, cost, solitude, something but there is no perfect answer here.

                But there is. Having an audio range that isn’t ridiculous, that allows you to hear whispers and not get your ear blown out by the louds. Unfortunately many movies don’t do this, and for some reason you would rather compromise on someone else’s comfort than even consider this?

                There is a perfect answer. Don’t watch movies with shitty sound mixing.

                I used to mix audio for my garage band’s albums in the 2000s. It’s not that hard to get effective dynamic range without setting the quiet parts to barely audible and the loud parts to red lining the db meter. It’s obnoxious.

                If I ever meet the guy who mixed Malignant, I’m going to “accidentally” spill my coffee onto to his mixing station. I couldn’t watch past the first scene. The mix was downright mean. That movie still pisses me off.
