The most immediately noticeable difference in a Dolby Atmos® system is the use of overhead speakers, but that's just part of the story. A typical surround sound system consists of left, center, and right discrete channels with the speakers behind the screen. Mar 18,  · Dolby Atmos is an audio format – like stereo sound or surround sound that takes recorded audio from a movie soundtrack or a video game and spits it out in a more immersive way.

Before the coronavirus pandemic upended life as we knew it, movie theaters were undergoing a renaissance of sorts. In the past, if there was an explosion on the right side of the what is dolby atmos surround sound, half of the speakers in the theater would play the same sound. With Atmos, the sounds in a theater could now come from distinct locations determined by the professional audio mixers that had arranged them.

This meant that, theoretically, theater operators were limited only by their appetite to add extra speakers and amplification. This being a top-to-bottom surround sound guide, however, we need to journey back before we can move forward. Surround sound, at its most basic, involves a set of stereo front speakers left and right and a set of surround speakers, which are usually placed just to the sides and just behind a central listening position.

The next step up involves the addition of a center channel: A speaker placed between the front left and right speakers that is primarily responsible for reproducing dialogue in movies. Thus, we have five speakers involved. In this case, matrix refers to the encoding of separate sound signals within a stereo source.

This approach was the basis for early surround-sound formats like Dolby Surround and Dolby Pro Logic and was motivated in part by the limited space for discrete information on early audio-video media, such as VHS tape. Dolby was able to allow home audio devices to decode two extra channels of sound from media like VHS tapes, which fed the center channel and surround speakers with audio. Because of the limited space, however, matrixed surround signals came with some limitations.

For instance, the surround channels in basic Pro Logic were not in stereo and had limited bandwidth. It was called Quadraphonic sound, and it first appeared on reel-to-reel tape. Unfortunately, Quadraphonic sound, which provided discrete sound from four speakers placed in each corner of a room, was confusing and short-lived — no thanks to companies battling over formats sound familiar?

Immersion in a three-dimensional audio sphere was not to be given up on, however. InDolby Laboratories introduced Dolby Surround, a technology that piggybacked a surround sound signal onto a stereo source through matrix encoding. Since then, Dolby, DTS, and others have helped advance the state of home surround sound with a variety of iterations. In the next section, we trace this evolution — from the standard 5.

Remember LaserDisc? Dolby took advantage of this and created AC-3, now known as Dolby Digital. This format improved on Pro Logic in that it allowed for stereo surround speakers that could provide higher bandwidth sound. All the information in Dolby Digital 5. Sorry, Keanu. To this day, Dolby Digital 5. Image courtesy of Dolby. Dolby more or less dominated the surround sound landscape for years.

Then, inDTS came along, providing its own digital surround sound mixing services for movie production, first hitting theaters with Jurassic Park. The technology eventually trickled down to LaserDisc and DVD but was initially available on a very limited selection of discs.

DTS how to take outdoor portraits a higher bit rate and, therefore, delivers more audio information.

Think of it as similar to the difference between listening to a kbps and kbps MP3 file. The quality difference is noticeable, but as with so many audio-related comparisons, not everyone is sold on it. The sixth speaker was to be placed in the center of the back of a room and was subsequently referred to as a back surround or rear surround. This is where some confusion began to swirl. Recommended speaker placement, however, has always called for surround speakers to be placed to the sides and just behind the listening position.

The point of the sixth speaker is to give the listener the impression that something is approaching from behind or disappearing to the rear. To make things even more confusing, each company offered different versions of 6. DTS, on the other hand, offered two separate 6. Just when people started getting used to 6.

Like 6. Those surround effects that once went to just one rear surround speaker could now go to two speakers in stereo. This development was enabled, in part, by the massive storage potential of Blu-ray. Those who bought a dedicated back surround speaker during the shift to 6.

Dolby offers two different 7. Instead of using matrixing, it applies lossy compression to all of the discrete audio channels, which helps to take up less space on a Blu-ray disc. Dolby TrueHD, on the other hand, is lossless. DTS also has two 7. DTS-HD is a lossy 7. Movie studios have to opt to mix for 7. There are other factors involved, too, with storage space being chief among them.

If a bunch of extras are placed on a disc, there may not be space for the additional surround information. In many cases, a 5. This is becoming less common, however, especially when it comes to 4K Ultra HD Blu-ray discs, which often support multiple seven-channel mixes. This processing mode is commonly used when watching non-HD TV channels with a stereo-only audio mix. If your video source is presented a little bit of what you fancy does you good 5.

Pro Logic IIx is subdivided into movie, music, and game modes. This form of matrix processing aims to add more depth and space to a soundtrack by outputting sounds from a whole new location in the room.

Since IIz processing can be engaged with a 7. Despite the addition of these height channels, Pro Logic IIz does not enable a true 3D placement of sounds. Both connections outpu t the same information since, as far as Dolby and DTS are concerned, there is only one subwoofer track. For most people, a single subwoofer will provide ample low-end bass and rumble.

However, adding a second sub can enhance this effect, especially in larger media rooms. Check out our subwoofer placement guide to learn why a second sub might be right for you. DSX also allows for additional speakers beyond the core 5. With the what foods to eat to make breasts bigger of front width and front height channels on top of a 7. For instance, you might hear a helicopter take off from in front of you, hover over your head, and then disappear into the distance behind you.

Because these channels no longer need to extrapolate their signals from audio running to other speakers as they did with Pro Logic IIz 7. As mentioned above, the most common configurations are 5. InYamaha introduced the first Atmos-capable soundbar, the YSPwhich uses up-firing drivers to bounce sound off the ceiling.

Since then, soundbar manufacturers have fully embraced Dolby Atmos. Some achieve the Atmos effect using dedicated wireless surround speakers with up-firing drivers to complement the front speakers in the bar. Others use a technique known as virtualized Dolby Atmos to convincingly simulate the Atmos effect using fewer speakers. Because Dolby Atmos can be calibrated for as few as two channels, we suppose this is technically accurate.

However, buyers should be aware that two-channel Atmos will never sound as good as discrete 5. Atmos is even starting to appear in some live broadcasts. How to cook rice crispy order to hear Dolby Atmos sound, every part of your home theater system — from the source to the speakers — needs to support it. Though still in its early stages, Dolby Labs has been working with major record labels and streaming services to develop the use of Dolby Atmos technology for music production.

The concept is simple: Dolby Atmos Music uses all the same object-oriented 3D audio tools as the movie soundtrack version but puts them in the hands of professional music producers. The result is immersive music that goes well beyond what traditional two-channel stereo or even Quadrophonic sound can achieve. Unfortunately, Dolby Atmos Music is very limited at the moment. The only way to hear it using a Dolby Atmos-equipped home theater is to buy one of the very few Blu-ray discs that contain a Dolby Atmos Music mix, like the recently remastered and re-released Kick by INXS.

In a few select clubs, Dolby Atmos Music is being used by DJs and other live performers to produce an immersive music environment for dance floors. Hopefully, Dolby will soon open the floodgates on Dolby Atmos Music and find more ways for folks to experience it. It too can be found on some streaming services, but as with Atmos Music, the devices needed to hear it are limited to just a few options for the moment.

DTS:X aims to be more flexible and accessible than Atmos, making use of preexisting speaker layouts in theaters and supporting up to 32 different speaker configurations in the home. Companies like Lionsgate and Paramount offer home releases in DTS:X, but its lack of widespread adoption on disc-based media — and zero adoption among streaming services — is its biggest how much do toronto raptors tickets cost factor.

DTS also recognizes that not all movie lovers have the space or the time to put together an object-based sound system. This technology first rolled out in soundbarswhich makes sense, as they often only include a separate subwoofer and maybe a pair of satellite speakers at most.

Thanks to Denon and Marantz pushing it through as a firmware upgrade, you can now use it with your home speakers — though you have to pay for it. Despite apparent likeness to Dolby Atmos, Auro-3D creates a surround-sound experience through a three-tiered sound system. Multiple speakers really showcase this kind of layered sound.

We recommend eleven speakers to get the most out of the sound, making Auro-3D the most expensive setup you can recreate at home.

You may well have heard of one, two or all three of these technologies.

But do you really know what they mean, how they work, and how they differ from each other? Prick up your ears, as we explain all.

Like its rival Dolby Atmos, DTS:X is an object-based audio format that can place sound in more specific locations around the room than with generic surround sound. Unlike its rival, though, it started life in home cinema devices in before being implemented in cinemas themselves.

The aim is the same as Dolby Atmos: to let sound move around the room in a more realistic manner to match the action on-screen, creating more immersive cinematic experiences. But the way it works is different.

Instead of requiring extra speakers like Dolby Atmos , it works with standard surround sound systems. So chances are the set-up you have at home — be it 5.

But DTS:X can support much more extensive systems too, comprising up to 32 speaker locations and up to an So just like Android , any manufacturer can create a system that will be compatible with DTS:X with no special permission required. For a start, Atmos started life in cinemas, only later coming to home cinema products like speakers and soundbars. Both Atmos and DTS:X are object-based surround sound technologies, but Atmos puts more emphasis on height — so much so that Dolby recommends you install ceiling speakers to get the full benefit.

But thankfully there are Dolby Atmos-certified speakers, TVs and soundbars with upward-firing drivers to bounce sound off the ceiling. The result? Atmos speakers also count towards the nomenclature of your system.

For a more extensive look at Dolby Atmos, check out our full guide. This is the real question. On paper, DTS:X has the edge in terms of sound quality because it supports higher bit rates.

DTS:X lets you manually adjust sound objects, so you can turn up the volume of voices, say. That will make hushed dialogue easier to decipher, which is something many of us have longed for during a Hollywood blockbuster. Plenty of AV receivers and surround sound systems support both technologies, so — as long as you have the right source content — you can enjoy high-quality audio whichever codec is used. If you want to link unrelated audio kit across different rooms of the house to create a multi-room effect, DTS Play-Fi can help.
