![]() (Aside: I was disappointed to see that even in 1982 they already applied the "letters showing up on the screen make weird high pitched sounds" trope.) (Or maybe this is because I normally don't pay that much attention.) I can't remember hearing that on a more recent movie. For instance, when cutting between Sark and Tron, the audio comes from a surround speaker when we see Tron but immediately switches to the center channel when there is a cut to Sark, and the other way around. I'm 100% sure that without that great sound design much of the visuals would have fallen flat.Īlso, as surround sound as we know it today was still in its early stages then (despite Fantasia (1940) being the first movie with multi-channel audio!) I think the Tron audio engineers made bolder choices than what's common today. If you have that title, give it a listen. This morning I popped in my Tron blu-ray because in addition to singlehandedly putting CGI on the cinematic map, it also got high praise for its audio mix back in the day in 40 years ago. That height speaker made up for me thinking it wasn't even there for months in that one moment. I wonder though if that's because the height speakers aren't really used all that much in mixes? The other day I was watching Ready Player One an at one point there was a shot from high right to low left. (And why TF is most of mu post orange? Don't mind the exztra spaces and such, typing this on one of those sucky scissor MacBook Pro keyboards.)Ĭlick to expand.Right. Still, when it works it works and that's pretty nice. The idea behind Atmos is that you can map the sound object to arbitrary speaker configurarions. However, I could ind no info at all about how this works.)Ī disappointment with my system is that it just assumes good speaker placement. So all the audio is in the DD+ or TrueHD mix, so then what happens with an Atmos-aware decoder? Apparently the object audio is subtracted from the regular 7.1 mix and then re-added to the appropriate channels. (One thing I wonder about: when I play back Atmos audio such as this 7.1.4 file over Atmos-unaware setups, I do get all the audio, although it is remapped to the 5.1 channels. So it seems Dolby Atmos is not a complete waste of time, but it's certainly not a game changer over a good 5.1 setup, either. it's fairly rare for me to notice any action in the height speakers. Changing this to front height helped significantly, but. But that pretty much didn't do anything, as the speakers were sending out their audio horizontallay as they were mounted on the wall just below the ceiling. Initially, I set up a normal 5.1 surround setup plus two height back speakers. Atmos also adds 2, 4 or 6 height channels, so sound can come from above.īack in 2018 I got an Onkyo surround receiver that can do Atmos and can handle 7 channels (+ one or more subwoofers). This meqns that extra audio channels can "fly around" the sound stage rather than be mapped to an individual speaker. Quick explainer: in a home theater setup, Dolby Atmos takes 5.1 or 7.1 surround in the form of Dolby Digital+ or Dolby ThrueHD and then adds "object-based" audio. However, we suggest that the height of the rear speakers not be more than 1.25 times the height of the front speakers.Do you guys feel having a Dolby Atmos setup is worth it? If the room design makes this impractical or impossible, the rear speakers may be positioned higher than the front speakers. If possible, the height of the rear speakers should be the same as the height of the front speakers. All listener speakers should be at the same height, typically 3.9 feet (1.2 meters), which is ear level for the average seated listener (as defined in ITU-R BS.1116-1).If this is not possible, compensating for distance may be used to time align the arrival of audio from each speaker to the listener. All speakers in the listener plane should ideally be equidistant from the listener position. The speakers located in the front of the room shall be used as a reference point.This is an excerpt regarding the issue (the bold is mine):Īs in the past, the placement of all listener-level speakers should follow these recommendations, which are based on ITU-R BS.775-3:
