I mean I think they've kind of changed the way they approach dialog from having everyone sort of yell all the time to just assuming that either you're in a theater or watching a tv with the volume extremely high, you have subtitles on, or you're wearing earphones

I don't see this as particularly problematic unless you want to have tenet on in the background while you cook dinner or something

Yeah there's been a few updates about that. The footage where she goes "I can't move, I can't think" is absolutely heartbreaking.

A vid about GPT/language models.


TLDW: language models use tokens. Tokens are either common words or parts of words or individual characters. That way, rare words can be represented by characters, but common words/sentences take up less space. The choice of what words are tokens is simply based on how common those words were in the INITIAL data set.

There are some tokens that are really weird such as PsyNetMessage and SolidGoldMagikarp.
If you use those in a message, GPT-3 completely glitches out and returns nonsensical crap (not in ChatGPT, that has been patched since this was discovered).

Why? Well, what happened is PsyNetMessage is a term that appears very often in some game's debug log that somehow made it into the initial data set, and SolidGoldMagikarp is the name of a reddit user who was extremely active in r/counting... where people just count up numbers. Whatever web scraper they used for the initial dataset picked those up as really common.

Then, when they actually started training the model, the researchers cut out those weird terms and used more sensible data. However, the tokens already existed at that point. Result: the tokens exist but there's basically no information associated to them. The language model has no idea what they "mean" or how to respond to them. This causes the glitchy behaviour.

Audio "expert" watches shows with subtitles on while saying it's actually fine

it was absolutely jarring to see her admit this. And also that the downmixing is done by "someone else" which makes no sense unless it is outsourced to some moron who costs pennies on the dollar. I think that's the real reason poo poo sucks so bad

This comment has the most technical and therefore correct explanation

I’m a re-recording mixer. This video leaves out what is in my opinion the biggest factor. They explained how a wide dynamic range has a negative effect in home environments but did not elaborate and did not explain that we have no choice but to mix with these wide dynamics due to network requirements, which most of us mixers want changed!! Television used to be mixed with very little dynamics. But now the line between TV and film is blurred and companies like Netflix want their content to “sound theatrical” so they require us to keep the dialog at a -27dB average while allowing us to peak at -1 for the big moments. That range is too wide for most homes because of the acoustic environment. Acoustics play SUCH a huge role in how we hear things, I can not overstate this enough. Without proper absorption in the walls and corners you get all kinds of buildups of certain frequencies that resonate the room, especially during loud moments. So often times it’s the room itself that’s muddying the dialog and not even the speakers or the mix. Any kind of natural reverberation in the room also makes dialog a little less intelligible so the natural response is to turn it up during the quiet moments. Then suddenly the loud moments become WAY too loud due too resonant frequencies in the room. The fix for this is to mix with a narrower dynamic range but the networks won’t allow us to do that.. for now. I always tell people to try listening in headphones and I guarantee you won’t be riding the volume up and down cause you’ve eliminated the room out of the equation.

I guess you could turn on dynamic range compression which will have the added bonus of making audiophiles angry

my yamaha receiver has an “auto” dynamic range mode that I enable for movies and it helps a LOT to prevent me from needing to always janitor the volume between dialog and action scenes. I wouldn’t normally care but I live in an apartment and would rather not be the rear end in a top hat neighbor

i also turn the center channel up a little bit after doing the microphone levels setup since most dialog is center channel

works for me and poo poo still sounds fantastic
