- 7-track audio? Boom tracks? Massive speaker deployments?
To better understand how to advance our home theaters we look towards the cinema systems we try to emulate in our homes.
See how cinema surround sound has evolved from Fantasound in 1940 to the immersive Dolby Atmos, Auro-3D and DTS:x object-based formats of today. Along the way we will cover Cinerama, CinemaScope, Todd-AO, Dolby Stereo, Dolby SR, Ultra Stereo, THX, Cinema Digital Sound, SDDS, DTS, Dolby Digital, Dolby Digital EX, DTS-ES, and Dolby Digital 7.1. - Zábava
The Most Iconic sound systems is Dolby dts and THX
Great explanation on how surround systems have evolved...Really makes the movie experience that much better..
My favourite is DTS. I've been a fan since Jurassic Park and nothing can change my mind. 😂
I remember when DTS was better than Dolby. I think Dolby Atmos is now the better sound format. I still like DTS too
Same. Especially on DVD.
I like IMAX Dolby and dts
I have a couple of blu Ray's with dts HD master audio 5.1 or 7.1
Same back in the height of the dvd era I used to hunt down dvd's just for that format alone. If the bac of the the case described DTS I would buy it over Dolby Digital.
I've been looking for this channel for years! Glad I found you again.
Laserdisc format offered everything at the time! Mono, stereo, analogue, PCM digital, Dolby stereo, Dolby Surround, Dolby Digital (demodulated to 350kbps from an AC3-RF carrier), Dolby Digital EX, DTS (at higher samples than DVD!), and a plethora of other stereo matrixed surround formats from Yamaha and Sony etc.
I look forward to more like this from your channel. 👍😎🇦🇺
Great video! Very educational. Had to play at 1.5 speed.
Glad you enjoyed the content. This was one of my first videos. I feel I should revisit this content again - perhaps I will be able to have a better pace with version 2. -Jon
Just a quick hello to all the other Nerds that love this kind of shit. & thanks to you for making this video.
I am learning a lot in the process. Not only while researching each video, but with the added knowledge from this community after the video is posted. -Jon
Dolby Digital would later be used by Microsoft for their Xbox video game console, which was released in 2001.
Thanks for raising how these surround modes entered into gaming. A point I hadn’t addressed.-Jon
Very nice video. 2 comments though.
First: when cinema moved from film to Digital Projection, one other advancement was made. DCP's that have up to 7.1 discrete digital channels have moved to Uncompressed PCM audio 24 bit 48kHz or 96kHz. The introduction of the 7.1 decoders also started the move to fullrange speaker arrays for surround speakers. Where before that, the surrounds were usually limited in their frequency response and the audiomix was treated as such.
The second thing is about the object based audio: the DCI is currently adopting a SMPTE standard called ST 2098, which is compatible with all 3 object based systems to standardise DCP production. Before you had to specifically create DCP's for each audio format. Barco's new Auromax decoder is the first that adopted this standard and the rest of the industry will follow soon.
This is great complimentary material which fills in details for some of the more recent years. Thanks for sharing.-Jon
i lowed that in the 90s and early 2000s the magazine Widescreen Review had a list in each issue detailing which digital surround format each movie had, that was showing at the moment in theaters. On another note, its really apparent taht SDDS was used for the first time in Last Action Hero, because that mix in Dolby Digital and later on 4K UHD in Atmos, is really aggressive.
For those who think he speaks too slowly play at 1.25x and it's perfect.
That is really funny. I have been trying to improve my delivery over the last year so such a work around is not as necessary. -Jon
Funny I did so automatically glad I'm not the only one who thought it was to slow great video though ❤
what a great video many thanks for this
Thank you for this very informative video!
Love your vids Jon. Learn so much from you. Keep them coming my friend.
Glad you are finding these videos entertaining. I took my first break this month but I am resuming this week. Thanks for watching.-Jon
a nice explanation will pass it on -THX!!
Joe - thanks for the support.
Great video Jon, somehow only you make videos answering many of the questions that I have about Surround Sound that nobody else covers or thinks about.
There's a theater near me that has Dolby Atmos, but I don't think they charge a premium for it. They do charge a premium for luxury seats or D-Box seats, though.
Good point. Typically Dolby Atmos is included with the standard price if the theater has it. They certainly charge more for IMAX, Dolby Cinema, 3D, D-Box (motion seats) and 4DX (motion + wind, heat, strobe-lights, simulated-snow, and scents) - and luxury seats. I like it when I can choose my own seat (assigned seats). -Jon
Superb sir 👌 very well explained 🔥
Thanks - I really enjoyed researching the content for this video. I was amazed how surround sound went back so far. -Jon
Wow nice information
One minor detail that you had listed on screen but probably could’ve emphasized more: the main difference between Dolby Digital Surround EX and DTS-ES was that DD EX had a matrix back center channel where the sound data was pulled from the mono audio elements from both surround left and right channels, while DTS-ES had a true (hence discrete) back center channel. In other words, DD EX was simply a 5.1 track and converted to 6.1 using audio processing for the back center while DTS-ES was truly 6.1.
Thanks for supplying this extra detail about Dolby Digital Surround EX and DTS-ES. Helpful. -Jon
DuckTales: Remastered (Capcom) is one of the video games to include Dolby Digital surround sound
Interesting- thanks for pointing out that video games can have great surround experiences.-Jon
Great video! Care to talk about IMAX sound?
I appreciate the suggestion and compliment. While I still want to cover IMAX cinema in more detail and learn more about IMAX sound at home I just posted the following which goes into IMAX in the most detail to date - Certifications - who's winning? THX or IMAX Enhanced? czcams.com/video/jHJAjwd4R-U/video.html - Jon
Dolby surround 7.1 digital isn’t that Dolby digital plus or truehd also thanks for explaining the early surround formats in cinemas I never understood them until now
From what I understand the Digital Dolby Plus and TrueHD brands were specifically introduced for the home market and were not used with the original cinema implementations.-Jon
@@ripewave oh right that’s probably why films like toy story which first had Dolby digital/surround 7.1 used the 7.1 mix because it is already in the original discrete studio mix but I don’t know why cinemas use the Dolby surround/digital even when the audio format isn’t Dolby
I Like SDDS
Reece Ganley - for the 5 channels on the front sound stage or for something else?
@@ripewave Maybe it is the feature that some Sony receivers used to allow front wall setup based on SDDS.
What are your thoughts on Bedini Audio Spatial Environment that was used on a several films encoded with Ultra-Stereo in the late-80s?
Hi, thank you for the video - very thorough and informative! I was wondering though, where did you get the numbers of movies released in each sound format? Is there a list available somewhere? Would really appreciate your reply. Many thanks!
I did find that data on websites. I will see if I can locate them again. - Jon
Thank you, that would be awesome!
My favorite format is DTS (not X, not HD Master Audio) because for me sounds very good theater like and is more practical because Dolby Atmos sound good but is not so practical because in order to have a very close experience like on cinema you have to have in ceiling speakers because with bouncing sound is not the same, so for now for me DTS is best, but is sad that format is not used anymore, and yes there is DTS HD Master Audio but for some strange reason for me doesn’t sound the same or best.
Juan - I too have found that a good dts/dolby digital 5.1 system can still sound very good. Jumping to immersive is costly. I am about to give the atmos/dts:x a try after years on the sidelines and saving my money up. It is like buying a second system - 2x the cost with all things considered. It will be interesting to hear the differences using the same room, speakers and amplifiers. -Jon
1.5x ahhh much better
Great video but DTS:X Pro has brought back the Left and Right LFE. So we now have 30.2 available in the home
Having so many channels at home is amazing. It certainly gives you the flexibility to configure how you would like. While the AV processors/receivers now support two or more independently controllable subwoofer outputs I have yet to hear of source material or decoding that provides discrete LFE left and right channels as with the early cinema implementations.-Jon
To be fair doesn't matter witch audio format just trying to impress me
I wish we could just play DCI movies at home I don't think there is any reason we can not
Josh - I don't know much about DCI and will have to research. Can you provide some more insight on the DCI theaters and their unique value? -Jon
@@ripewave movie are much bigger the blu ray and streaming less compression I think they are 2 and 300 gigs it is what is use at pro cinemas
You cannot play DCI movies (called DCP’s) at home. You’re home projector can’t play then to begin with you need a DCI compliant projector with a media block to de encrypt the encrypted content and a digital cinema server and the studio would need to issue you a key (called a KDM) and they won’t issue keys to non first run theatres for news films.
@@seanmckinnon4612 Not actually true...you just have to be incredibly rich to do it. Seach up Bel Air Cinema on the web and see for yourself. Oh, and save up your pennies, because you're going to need them!
I want Charlie Chaplin in 7.1 dts.
How many frames per second?
What About Datasat ? you forgot that one
German - the intent of this video was to focus on cinema formats and theater configuration. If Datasat was involved with those I would be interested in learning more. I know Datasat as a provider of commercial cinema and high end home theater processors. -Jon
Datasat is the new name of DTS. ;)
@@ataruist Dts still being Dts , datasat is another audio format independiently , check out their website
U forgot thx
Yes, I debated that at the time and probably should have mentioned it. As THX is a measure of the quality of the installation vs. a sound format it is in a somewhat different category. However, you are right that it is significant in cinema sound reproduction. - Jon
THX is not a “sound system” it is a set of guidelines a theatre must meet including equipment specs, a baffle wall, and sound isolation of the room among others.

One of my first videos. I no longer script. -Jon
