It may not be as good as a true 5. To expand to 7. This means that your receiver should have 2 extra channels for this Dolby processing mode to work. Dolby TrueHD is a lossless 5. This is a large-sized file that is mainly stored in Blu-ray disks. However, not all receivers can decode this codec but if your source such as Blu-ray has a decoder for a Dolby TrueHD file, you should be able to play the file by bypassing the processor on your receiver.
Dolby TrueHD is better than Dolby Digital as it is stored in a lossless format and has more information for the sound processor to work with and create a hi-res immersive surround sound with a better dynamic range in your home theater system.
Dolby Atmos is a lossless object-based 3D surround sound codec and processing mode. It is an extension of Dolby TrueHD that adds an extra height element to create a bubble around the home theater user.
It is mainly used in a 5. Having such a system, a Dolby Atmos source, and a Dolby Atmos processor, will enable you to have an immersive 3D surround sound experience. The sound effects will make you feel like you are interacting with the environment similar to what you are watching, whether is an overhead chopper, flying bullets, birds, leaves falling, and so on.
However, you cannot experience Dolby Atmos if you do not have height speakers, ceiling speakers, or even up-firing speakers that bounce soundwaves off your ceiling. Dolby surround is a sound processing algorithm that works with a system tailored for a Dolby Atmos surround sound but without needing Dolby Atmos content. This means that it can up-mix a standard 5. Dolby Surround can also work with stereo content and up-mix for surround sound and allocate sound signals to the various speakers that you have in your set up.
Dolby Atmos Height Virtualization is a Dolby surround sound processing mode that aims to create a virtual 3D Dolby Atmos effect without needed height or in-ceiling speakers.
This will save you from the hassle of having to fit speakers in your ceiling or buying up-firing speakers that do not always work great in all home theater rooms. However, you will need a receiver, preamp, or processor that can support this mode and can be used in a 5.
The processor is fitted with height-cue filters that can emulate that immersive bubble effect with your current surround sound system.
If you have a receiver, you can contact your manufacturer to confirm if they have a firmware update for this virtual processing mode and try it out. However, if you already have speakers for your height channel, this will not be necessary. It is a direct competitor to Dolby Labs but was founded later on in after Dolby had been in the industry for some years. DTS technology made a major milestone after it was used in the movie Jurassic Park which propelled the company to popularity.
This sound technology also uses lossy compression but is sampled at a higher bit rate than Dolby Digital and is also more adaptable to different rooms and home theater systems. This is because DTS uses software that can analyze the speaker system, tune changes in different ways, and can optimize bass depending on your system and subwoofer. But just like DD, DTS has developed different codecs and processing modes that can be used in a home theater or media room.
DTS-ES 6. DTS Neo:6 is a DTS decoding mode that up-mixes a stereo 2-channel audio file and distributes it to 6 channels for a 5. DTS Neo:6 comes in two versions where one is optimized for music listeners and the other for watching movies in Music and Cinema respectively. DTS-X is an object-based sound format and decoding mode and is a direct competitor to Dolby Atmos but is different in that it does not need height, up-firing, or even ceiling speakers to create an immersive experience.
Both formats use compression to save space either on the disc, in the case of DVD and Blu-ray, or streaming bandwidth, in the case of services like Netflix. But we can look at some of the specific specs available and make a rough determination. As you can see, the propagation of two competing companies with evolving standards has resulted in roughly comparable levels of surround sound quality across three different tiers.
At first glance, DTS seems to have the clear advantage on paper due to its higher bitrate encoding at all three tiers.
The difference between the lossless and lossy tiers is highly subjective as well, not to mention dependent upon the quality and setup of your specific home theater. The differences in bitrate between the lower and upper tiers will become more apparent with more expensive, higher-quality speakers…assuming that your hearing is actually good enough to discern the difference in the first place. In addition, the values above represent the maximum optional channels and bitrates for each tier.
Studios have to pick and choose which formats to support on each release, and at which maximum quality. For example, Blu-ray. The latest Blu-ray releases tend to stick to one or the other for their highest-resolution option, either TrueHD or Master Audio, then defaulting to a more compressed option like standard Dolby Digital 5.
If you want something extremely cutting edge, you might want to look into technologies like Dolby Atmos or DTS:X, and which specific receivers, speakers, and movies or services support them.

Your receiver, during playback, then decompresses the files. Both audio standards also implement extra technologies like encoders specifically for enhancing stereo, an older Pro-Logic standard for simulating surround sound.
The codecs also convert down or up to match the number of speakers, enhance surround sound and other tasks. The formats make use of compression technology to save space on DVD, Blu-ray or during streaming. You will also come across lossy DTS and Dolby Digital, which means that audio is degraded to a certain degree from the original source.
Others offer lossless studio level performance while offering some sort of space-saving compression. Comparing Dolby Digital vs. DTS surround sound in home theater applications reveals that both formats are close together in terms of audio performance.
However, media used in your home theater do not always support the max raw-bit rate that each format supports. Therefore, you are likely to achieve a better surround sound experience than in a movie theater with a Dolby Digital soundtrack when using a properly equipped home theater.
On the other hand, DTS sound in the home may not achieve the same level of sound quality available in a DTS movie house installation because of reduced bit rates. You can compare sound quality using the same audio format using different bit rates to determine if the same format sounds better in a movie house or home entertainment situation.
Unfortunately, the decision is not so straightforward while examining different formats in a home application. To answer the original question of which format is better, it all depends on your individual overall experience. The DTS:X or Dolby Atmos are great options when you are looking for something truly cutting edge — as long as your receiver, speakers and movies support them.
In case you have to choose between two equivalent Dolby or DTS tiers and have no personal preference, choose the DTS for its higher bit rate. However, remember that actual audio quality difference is subjective.
