Since 2014, Dolby has totally revamped its Dolby Surround technology. This aging technology is lackluster in terms of dynamics, and the sound produced by the surround speakers is not free of artifacts, especially with highly compressed stereo signals (TV or set-top box, for example). In this way, a stereo signal is transformed into a 3.0 – 5.1 multichannel soundtrack. Dolby Pro Logic II and DTS Neo:6 separate the stereo signal emitted by the source ( TV, Netflix, etc.) by extracting sounds which are redistributed over all available channels. Both are also relatively outdated, although certain amplifiers lacking Dolby Atmos compatibility still implement them. These two audio post-processing techniques share very similar operating principles. Gone are the days of Dolby Pro Logic and DTS Neo, eclipsed by entirely revamped technologies from Dolby and DTS.

The difference between both audio formats is almost imperceptible. Both techniques provide a true-to-life reproduction that comes close to the original and the average listener will therefore not notice the difference. It actually comes down to your own preference. If both formats are supported by your receiver, try them both and make your choice. Of course, both audio tracks must be available on a Blu-ray disc, which is not always the case.The widespread compatibility of today?s AV receivers with immersive home cinema formats (Dolby Atmos and DTS) has spurred a revolution in post-processing and upmixing technologies used for 5.1 surround sound installations. DTS-HD Master AudioĭTS-HD Master Audio, like Dolby TrueHD, offers an audio reproduction that is almost identical to the original audio of the film, as the director intended. The audio format has a bit rate of 24.5 megabits per second and supports an almost unlimited number of surround channels of 24 bit, 96 Khz audio.

Dolby TrueHDĭolby TrueHD can reproduce audio data at a speed of 18 megabits per second and supports eight channels of 24 bit, 96 Khz audio. That may sound a bit complicated, but the bottom line is that the reproduction of details and the range of the audio is many times higher than, for example, Dolby Digital. This format provides a richer reproduction of the audio, bringing it very close to what the director of a movie has in mind. If you have a receiver without DTS-HD Master Audio or Dolby TrueHD support and select one of these formats when watching a Blu-ray movie, audio will still be played in the form of the original DTS or Dolby Digital track. This is always sent along with the HD audio format.
