If you've ever watched a movie, played a video game or listened to music on your TV, then you've probably heard Dolby Audio. It's the technology behind some of the best-sounding audio products in the world. In this article, we'll talk about what Dolby Audio is and why it matters for your TV.


Dolby Audio: What is it?

Dolby Audio can be used to provide an immersive, 360-degree sound experience—but you don't need a fancy surround sound system or even a home theater to use Dolby Audio. All you need are some speakers and your TV. However, not all TVs offer this feature—so it's essential that you check whether your new set has it before deciding on which one to buy. Typically, most mid-range and high-end models come with Dolby Audio or DTS audio (another popular surround sound technology), but be sure to check your TV’s specs before making your purchase so there aren't any surprises later on. Here at TCL, we have a TCL 4K HDR Google TV that offers Dolby Audio. It’s designed to immerse yourself in every scene – with incredible clarity, crisper dialogue, and great detail.


Dolby Audio is a system for encoding and decoding audio signals. It allows for multiple channels of audio to be encoded in digital form and played back at the same time via multiple speakers to create realistic surround sound experiences. This makes it ideal for watching movies or playing games where immersion is important because sounds will seem like they originate from different places around you rather than from one point in front of you (mono).


Why do you need it on your TV?

You probably don't think about the sound quality of your TV. But in reality, it's a big part of how we experience movies and TV shows. Dolby Audio makes the sound clearer and more dynamic than standard audio by increasing its volume levels while lowering background noise—and that means it does a lot for both movies and games (you know, if you're into those). It can also help with something called spatial sound which helps you hear quiet sounds or pinpoint where they are coming from when there is an explosion or something happening off-screen in a movie or show (like when someone says "Look out!" while they're hiding behind the couch).


How can I get it on my TV?

• Dolby Audio is available on most smart TVs. Most smart TVs have a built-in processor that will allow them to play back content with Dolby Audio, so if you already own a smart TV or are about to buy one, then this should be very easy for you. All you have to do is turn on your TV and look for the Dolby logo.

• Dolby Audio is available on soundbars. You can also get Dolby Audio on your TV through a soundbar. Soundbars are wireless speakers that connect to your TV, and they're often used for people who don't have a home theater system. They're good for watching movies or playing games with friends in the living room because they give you surround sound without the need for running wires throughout your house. When shopping for a soundbar, make sure it has an HDMI connection so that you can plug it directly into your TV instead of having to use cables coming from the rear of the set itself.

• Dolby Audio is available on streaming devices. If you don't own a smart TV and want Dolby Audio, you can get an external device like the Roku Ultra or Chromecast Ultra. These devices work with pretty much any HDMI cable and connect directly into whatever device(s) you want them too (like game consoles).


Dolby Audio vs Dolby Atmos vs Dolby Vision

Apart from Dolby Audio, you may also heard of Dolby Atoms, Dolby Atoms IQ and Dolby Vision. What are they? 


Dolby Atmos was created as an extension of Dolby Audio, allowing for an even more immersive experience when watching movies or listening to music in surround sound. Instead of having speakers set up all around you in fixed positions (like with 5.1 and 7.1 systems), Dolby Atmos allows you to move your speakers anywhere within your room—even behind your couch or under your coffee table! This gives you the freedom to arrange your living space however you want it and still get great sound quality from every angle in your home theater setup. 


Dolby Atmos iq uses software to create 3D sound, which allows you to hear sounds from all directions in a room. This can be done through a combination of speakers and headphones that have been calibrated to work together. The process relies on sound waves bouncing off walls and other surfaces, then reaching the ears of listeners at different times depending on where those listeners are located within the room. The delay between when each ear hears a sound allows your brain to create an accurate representation of where it came from—and thus create an accurate representation of where it was made by whatever object is making that sound.


Dolby Vision is an image enhancement technology that was designed for use with Ultra HD TVs (UHDTV) but can also be applied to regular HDTV content as well as streaming platforms such as Netflix or Hulu+.


Enhanced Audio Experience: Dolby Audio vs Dolby Atmos

In the quest for the ultimate home entertainment experience, Dolby Audio and Dolby Atmos stand out as two pivotal technologies. While Dolby Audio sets the stage with its immersive sound capabilities, Dolby Atmos takes the experience to new heights with its object-based audio system. Dolby Atmos transcends traditional channel-based audio to bring a three-dimensional soundstage into your living room. By incorporating overhead speakers or using ceiling-mounted speakers to reflect sound, Dolby Atmos creates a more enveloping audio environment that makes you feel as if you're inside the action.


The distinction between Dolby Audio and Dolby Atmos is not just in the technology but also in the content. Dolby Atmos-enabled content is specifically mixed to utilize the additional channels and height speakers, providing a richer and more detailed audio experience. Whether you're watching a blockbuster film or enjoying a live concert, Dolby Atmos delivers a level of realism that standard audio simply cannot match.


For those looking to upgrade their home theater, Dolby Atmos is the pinnacle of audio innovation. It's not just about having more speakers; it's about how those speakers work together to create an audio experience that is truly immersive and lifelike. As the demand for high-quality audio continues to grow, Dolby Atmos stands as a testament to Dolby's commitment to pushing the boundaries of what's possible in home entertainment.



Dolby Audio is a smart way to make your TV sound better. It can create a surround sound effect by simulating the position of different sounds in three-dimensional space. This technology makes it easier for you to hear your favorite characters talking or music playing from all sides, making watching TV more immersive and enjoyable. TCL Smart TVs are equipped with Dolby Audio to provide you with high-quality dynamic surround sound, check out TCL Smart TVs now to get the most immersive experience possible at home!
