Nowadays, more and more advanced audio technologies are developed. Among all the advanced audio technologies, Dolby True HD and Dolby Atmos are the most popular, and the most confusing ones in the industry. Are they the same thing? Which one of them is better? Let's find out together.

Part 1: Is Dolby TrueHD The Same as Dolby Atmos

If you are wondering whether the Dolby TrueHD and the Dolby Atmos are the same things, then the answer is clear: they are not.

Although both sound technologies are developed by Dolby Laboratories, Inc, an American company specializing in audio noise reduction and audio encoding/ compression, they are actually very different from each other. First of all, Dolby TrueHD is a lossless audio codec that supports up to eight audio channels on Blu-ray Disc.

Dolby Atmos soundtracks, on the other hand, consist of up to 128 audio objects that are mixed in a 3D sound field during the production process. Also, Dolby Atmos and Dolby TrueHD are two separate soundtrack formats. But Atmos data on Ultra HD Blu-ray is actually an extension to TrueHD that is folded into the bitstream to maintain backward compatibility.

As mentioned above, although the names look similar, Dolby Atmos and Dolby TrueHD are actually two separate soundtrack formats. Here is how these two sound effects work: When the soundtrack is played back in a movie theater or home environment, the audio objects are rendered by an Atmos decoder to the available speaker set, which includes overhead ceiling speakers. Normally, the Dolby Atmos effect is applied before the Dolby True HD if both of the options are on. That is to say, if you play a disc with an Atmos soundtrack, the Atmos extension data is decoded by an Atmos-compatible receiver. If your receiver isn't Atmos compatible, the extension data is ignored and the soundtrack is decoded as regular Dolby TrueHD.

Part 2: What Do You Prefer? TrueHD Or Atmos

After reading the introductions above, I believe you have already known that the Dolby True HD and Dolby Atmos are not the same things. Therefore, here comes the question: Which of these two advanced sound systems is better and can bring us more sound enjoyment?

In fact, the answer to this question could vary from person to person. Some people can sense the differences between the two sound effects almost instantly, while other people can't even feel the difference between them. If you want to know which one of the two sound systems can bring you more pleasure when you are watching a movie, it's better that you experience both of them for yourself. With that being said, there are indeed some differences in the playback that these two sound systems could bring. If you want to know which one suits you better without experiencing them both, then the information below might give you some insight into the differences between the Dolby True HD experience and the Dolby Atmos experience.

First of all, if you enable Dolby TrueHD and disable Dolby Atmos, you would have a great surrounding sound effect, especially if you have a set of 5.1 channel sound equipment. This is a really nice experience for people who seek for an immersive movie-watching experience. If there is also a 3D technology applied on the picture, then you will definitely get an ultimate immersive movie-watching experience and feel like you are actually inside the fancy world created by the movie. If you enable Dolby Atmos and disable Dolby TrueHD, on the other hand, the sound effects would be more realistic and more dynamic. Because there are 128 audio objects that are mixed in a 3D sound field during the production process, Dolby Atoms could bring you an ultimate realistic movie watching experience.

So the conclusion is, for people who seek for immersive movie-watching experience, Dolby TrueHD is a better choice; for people who prefer realistic sound effects, Dolby Atmos can definitely bring you more pleasure. But for the best movie-watching experience, it's better if you enable both of the sound effects. Also, don't take my word for it, you better experience both sound effects by yourself to know which one suits your ears the best.

Part 3: Best Free Player with Dolby TrueHD & Atmos Support

If you want to experience Dolby TrueHD or Dolby Atmos, having the movie that supports these sound effects is not enough. Besides the good movie material and a good set of stereo sound equipment, a decent movie player application with Dolby TrueHD or Dolby Atmos is also necessary.

Part 5: Conclusion

Today we talked about the Dolby TrueHD and the Dolby Atmos. From the introductions above, we know that Dolby TrueHD and the Dolby Atmos are not the same things. Dolby TrueHD is a lossless audio codec that supports up to eight audio channels on Blu-ray Disc, which can bring you a great immersive and surrounding sound effect. Dolby Atmos soundtracks, on the other hand, consist of up to 128 audio objects that are mixed in a 3D sound field, which makes the sound effect more realistic and dynamic.

It's obvious that both Dolby sound effects can boost your movie-watching experience, and you can only pick the best one for you after trying them by yourself.
