Dolby Atmos or Dolby Digital Plus?

Dolby Atmos or Dolby Digital Plus

The components should be fed with the highest possible source material. If done in that manner then it does not matter whether someone uses DTS or Dolby Atmos as they will receive a thrilling home cinema entertainment n both cases. Despite the argument of Dolby having more efficient codecs than DTS codecs, meaning a better and clear sound, one can expect a fine home cinema experience from both. At most times, the choice of your soundtrack will be influenced by the type of source material.

The Dolby Atmos | The Dolby Digital Plus

There are several differences between the two software. Certainly, Dolby Digital Plus is a digital audio compression scheme. On the other hand, Dolby Atmos is the name of surround sound technology. Atmos features a limited bandwidth as well as a lack of processing power and therefore not rendered the same way in home theatres as at cinemas. A spatially-coded sub-stream that represents an efficient representation of the full, original object-based mix features on Dolby Digital Plus. Important to note is that the substream is not a matrix-encoded channel. But a spatially-encoded digital signal that has panning metadata. In-home theatres, Atmos can support 24.1.10 channels. It uses the spatially-encoded sub-stream to mix the audio presentation to enable it to match the installed speaker configuration.

Secondly, Dolby Digital designates 2.0 up to 5.1 or more channels in the case where the speakers are arranged horizontally. The designations include Dolby Digital, Dolby Digital EX, and Dolby Digital Plus. The next step involves Dolby TrueHD, but the speakers feature a horizontal arrangement.

On the other hand, in the Dolby Atmos system, speakers feature horizontal arrangement as well as vertical. For example, 3.1.2, 5.1.2, 5.1.4, 7.1.2, 7.1.4. The first number represents the number of horizontal speakers, the second number represents the subwoofer, and the third number represents the number of vertical speakers. Noteworthy, vertical speakers may offer to hang on the ceiling or pointing up from the top of the horizontal speakers. The information on Dolby Atmos features encoding within a Dolby True HD signal that is in the case where one has a Dolby Atmos Blu-ray, and Dolby Atmos decoding is not on your receiver.

Dolby Atmos offers object-based as it supports more channels and can either higher quality with Dolby TrueHD or powered using Dolby Digital Plus as well. Using Dolby Digital Plus, you can achieve Dolby Atmos. Dolby Digital Plus features an enhanced form of AC3 with a lossy 5.1 track encoding. ON the other hand, DD+ adds additional channels, up to 20 but here the kicker appears as a DD+ soundtrack thus Atmos as well. Atmos metadata features attaching to the 5.1 channel signal thus mixed over the top, therefore, giving ATMOS height channel sounds.

Compression rates

Dolby Digital Plus

The compression rates is also another critical point in distinguishing the two. Dolby Digital utilizes a bit rate of 640 kbits/s to compress a 5.1 digital audio down for Blu-ray discs. However, for DVDs, it compresses using a slightly lower bit rate of 448 kbits/s.

On the other hand, DTS compresses audios at higher bit rates of up to 1.5Mb/s compared to Dolby Digital for Blu-ray disks. For DVDs, it utilizes up to 768 kbits/s to compress.

As one steps up to the competing HD formats, the compression gap widens. Dolby Digital Plus utilizes up to 1.7Mbps, while DTS-HD High Resolution is possible with up to 6Mb/s. Theoretically, if during encoding, the compression was less than that means more detailed audio will be delivered with a track almost close to what was initially intended.

In conclusion, DTS because of a higher bit rate promises a more realistic movie experience, thus beating its rival. However, other factors such as signal-to-noise ratio and speaker calibration would rate Dolby above DTS. So because of those slight differences and constant improvements in technology, in the case where one wants to upgrade their movie night, they should ensure that they have good-quality components, which are set up correctly.
