Dolby Technologies How They Work 1990
Ғылым және технология
In 1990 Dolby Laboratories released an informational LaserDisc to show the basics of how their main sound processing technologies worked. It was sold to dealers but also to curious customers.

It's crazy watching this now, most of us enthusiasts have Dolby Atmos in our homes.

Still you need pro-logic to play all your stereo mostly musics from mobile-phone laptop or cd to play them in surround sound.

@GauravSingh-px8rh The other thing is I believe most walk-in cinemas are 5.1 And the one drive-in we still have plays in stereo from car system. I think the mono window speakers went years ago. They actually do good business, probably the nostalgia thing. Back in 70's it was almost 1 drive- In every 10 kilometres.

I got to borrow this on VHS from a distributor of Dolby equipment back in the early 90s. It's good to see it again.
There are so many of those "analog horror" videos out nowadays that watching a normal old school informational video makes me expect something scary to happen.

there are a lot of videos about AM Radio antenna, watching an old video about cooking in outdoor barbacoa time makes me think something will happen. *a no sense and very fool comment as yours* do you think people will admire and consider your life as important with that kind of "participation" ? get a life. grow reading Og Mandino
SWEET! I worked as an AI Certified Film Projectionist for the better part of 7 years ( during about the time this was produced ) even though this disc is most about consumer Home audio gear. BTW - YES- I own a Laserdisc Player.

I have seen so many movies in old Dolby theater in the old building. My late husband worked there as a sound engineer before he moved to Brisbane which was closed in 2011 or 12, don't remember exactly. My most memorable was Paganini since Klaus Kinski brought it there and Trilogy of Lords of the Ring. We also stayed in Wiltshire when he was helping with setup of computers in Wooten Basset when Dolby moved there from London in 1992

Well, that sound system is overheated.
Dolby HX Pro is (imo) underrated. When I listen to prerecorded content mastered with HX Pro I'm usually very happy or even blown away.

I'm definitely not an audiophile but I've recently restored a consumer market Pioneer tape deck with HX Pro and it's truly amazing what it does with cheap ferro/type-1 tapes. Of course you notice a slight difference with the source material: some minor background noise at full volume and a slight cut of higher frequencies but still, the result is nothing short of astonishing.
Very interesting info, thanks for sharing
Zero dislikes, that's amazing!

If you think that's good then you should try listening your same sources with the new Dolby Surround Upmixer. The Dolby Surround Upmixer is so much better than all of the Pro Logic, Pro Logic II and Pro logic IIx decoders. The new Dolby Surround Upmixer is the replacement of the old Pro Logic decoders. You still can have 7.1 but you add top speakers that are used for the Dolby Atmos Surround and dts X Surround.

Ironically, this may be a Laserdisc on Dolby technologies but it was the CX noise reduction system developed by CBS which was integrated into virtually _all_ Laserdisc players ever made.

Or at least for the analog audio tracks.
I'm amazed by how bad LaserDisc looks, I remember thinking at the time, "there is no way it can get any better than this".

Well, laserdisc was an analog signal so it's subject to all of the issues that can have.

It looks really good on a CRT, like it was designed for. Even VHS still looks good when viewed on one.
I'm here because some N64 games supports surround sound I wanted to know how does it works

Sometimes grainy VHS conversions aren't a new analog horror series. Sometimes they're just grainy VHS conversions.
This is so cool

After 4 years this video is growing.
Lol when this was made, Dolby Digital was just around the corner.
Who’s this narrator? He’s familiar. He must’ve done the info tapes that came with old Chrysler stereo systems.
"Tommy" was the first one actually.

You might know this by now, but there's so many things you got wrong in this video. I also know exactly where you got some of your info and why it's wrong :/. I'd note it all, but I'm on my phone, and it was a lot of stuff.
Man I hated Dolby NR sucked out all the shine and brightness out of a song. Never used it. I rather hear some noise than lose the shimmer of cymbals or the air in a vocal performance
