I feel like the real issue, is that we only get one volume bar. If it was normal to define both the minimal and maximal volume setting and have the players stretch the given dynamic range into that then it would all be good.

I have dabbled in video editing and it is SO easy to manipulate and level the audio track so that dialogue is louder than music and sound effects. This has led me to believe that movies where this is a major problem like Tenet are absolutely mixed this way on purpose, and the only reasonable conclusion to draw from that is that Christopher Nolan is insane.

Mostly, it's a downmixing issue.

The movie is mixed to have Music, Speech, SFX spread out through 5.1 or 7.1 The speech and primary important sounds come through center. General music is a mix of L,R and Surround. When you feed that audio track to a dumb tv, it does a horrible job at turning it into L and R sound only.

If you feed it through a good 5.1 or 7.1 receiver or soundbar, you get options for Speech and surround and you can mess with levels individually. But the speech is front and loud.

If I just plug my roku into my tv, the center channel is almost at, all I get is the light intermixing of center in L and R so speech is horrible. you jack up the volume to hear the speech, then all the other sound is way too loud

Likewise, in most cases just taking an AAC and convert it to mp3 without adjusting the levels, it ends up sounding like trash.

How can we set volume of music, SFX and voice separately, in games but not in movies?

In games these categories of audio are calculated and mixed locally in real time, for movies they are mixed down to a single track and compressed ahead of time.

These days having three audio tracks would not be a significant problem, compared to the high resolution video track. But I guess the industry never changed.

I could already hear the forums filling with desync complaints

You could on laserdisk, but dvd got more popular

Because a video game is a program that can change it's behavior as it's running.

A video is a recording. It's already been recorded.

incorrect. movies are streams of multiple layers of content.

  1. video
  2. environment audio
  3. effects audio
  4. vocal audio

environment audio are things in the background like cars, birds, children playing.

effects audio are sound effects like breaking glass, car crashes, explosions.

vocal audio is just that, the dialog between characters.

streams MUX these together into a playable movie on the fly and is how it's possible for them to use the same movie with different language dubs.

it's completely in the realm of possibility for them to create a control to manage the volume of each of these layers before muxing. that would break their caching strategy though.

physical media like Bluray should be able to do it though. BD players never implemented such a feature that I am aware of.

You can record multiple channels, you already have left and right recorded separately. Other channels could exist for different things, it would just need a standard to follow to be useful

It's called compression, and most players have it in the settings somewhere. Quick and dirty is to up the volume in vlc to like 120% and lower it in system.
