Dolby has been in the game much longer than DTS. Dolby Labs was founded in by Ray Dolby, who patented many innovative audio systems. The first movie that used Dolby Digital technology was Batman Returns, way back in Dolby came a long way since then; they made codecs like Dolby Digital Plus for HD sound for surround systems, supported 7.
Their lossless format is Dolby True HD, which aims to replicate the quality of the master recording of a movie studio, and does a pretty great job of it. The most modern and innovative audio system Dolby invented is Dolby Atmos, which is an object-based system. DTS and Dolby Digital are both amazing and they provide excellent surround sound feeling. However, there are differences between the two which can be used as a determining factor when choosing one over the other.
The bit rates and the amount of compression differ greatly between the two. DTS has a higher bit rate support and lower amounts of compression. For the standard 5. On the other hand, Dolby compresses the same 5. 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.

A post-processor named the Object Audio Renderer translates the soundtracks and the metadata in the bitstream into channels based on the number and characteristics of the speakers available in the playback system.
It offers output support for Dolby Atmos devices can handle legacy channel-based content also apart from Atmos-enabled content. Conversely, the higher bit rates also mean that it is generally less lossy than AC It is based on a similar architecture as Atmos, i.
