The Three Immersive Sound Formats (Atoms, Auro-3D & DTS:X)

Audio just like technology doesn’t remain at a status quo, it revolutionizes just as fast to keep up with all the technological advancements. Back then in the past, sounds from movie theaters and music concerts were just okay. There were not really capturing the essence of the theme and making the audience feel immerse and connected to the movies or songs. But then in 1957, a musician, Henry Jacobs, conducted the very first concert using immersive sound. Only then onwards, people started to realize that audio, when heard that way really gives the listeners a form of connection to what they’re watching and listening to.

What is Immersive sound?

Immersive sound or immersive audio means that the sound you are hearing is coming from all around you, from up, below, right and left of you. Basically making you feel like you have immersed in that dimension. Immersive sound has been introduced into songs and movies ever since. Making millions for those records produced and movies released all thanks to immersive audios.

Before immersive sound, literally everything was produced or recorded in mono audio channel. Doesn’t matter if there were several speakers placed everywhere, they all played the same thing which is mono sound channel. Now, with immersive sound, speakers place at every angle, even on the ceiling or floor you name it. You’ll be able to hear differentiating sounds from different speakers. It’s so realistic and lively, you really feel like you’re one with the characters or singers, getting all the emotions and goosebumps. Plus, even new technology such as laptops, headsets and smartphones all now has immersive sound formatted in them.

Types of Immersive sound formats:

For your information, the immersive sound does come in 3 different formats:



Atoms or otherwise known as Dolby atoms is basically an immersive sound format that was introduced to the world in 2012, at a theater through the movie “Brave”. Dolby atoms is a sound technology by cinemas globally and also as a home theater sound support as well. It uses 5.1 (5 channels surround sound with one low-frequency channel) for home cinemas and 7.1 and 9.1 layouts that support 8 and 10 sound channels with 1 low-frequency sound channel for each layout too and that’s for movie theaters. The low-frequency channels are designed to lower the pitch of certain audio such as bass and that’s call subwoofer.



Auro-3D is an immersive sound format that has been created to support 3 layers of sound which include height, surroundings and ceiling. Normally, the traditional sound system was actually 2 dimensional and doesn’t really capture the feel of the audio. Auro-3D is creating to fit the horizontal layer by providing sound all round, from a height, top at the ceiling and also from sideways, obviously. Plus, this particular sound system has the same 5.1 and 7.1 layouts as Dolby atoms. Which means it has the same 1 low-frequency sound channel and 6-8 sound channels.



DTS:X, an audio system created by Digital Theater System, Inc. which is a company that makes audio channels for videos.

This particular company has made several sound systems such as

  • DTS 70 mm
  • DTS-ES, DTS Neo:6
  • DTS Neo:X, DTS 96/24, DTS-HD High-Resolution Audio,
  • DTS-HD Master Audio
  • DTS Virtual:X
  • DTS Connect
  • DTS:X, DTS Neural:X
  • DTS Headphone:X
  • DTS Play-Fi and many more.

But, DTS:X is what we’re focusing on because this audio format consists of the combination of Dolby Atmos and Auro-3D immersive surround sounds. It processes sound and then dynamically delivering it to the speakers, based on the location you’ve positioned it. Similarly to the other 2 immersive sound formats listed above, DTS:X has 7.1 layouts too, meaning 8 sound channels and one is of a low-frequency sound channel. So, it all depends upon the placement of your speakers only.

We’ve all now learned how technology even has a superior and positive impact on sound systems. Never would we complain about the fact that audio was ever so bad when it was at the 2D sound system. We gladly listened and enjoyed it. But as the world globalized and technology can’t stop progressing alongside it. People ended up with the thought of making an immersive all surround sound system.

The audience were shocked by the drastic enhancement. Making them fully absorbed into whatever it is they’re listening to. Taking them away from Earth for a while into another dimension. That’s how powerful and satisfying an audio sound system could be and both the records and movie production industry know how to optimize it to its full potential.
