Dolby Atmos is an object-based surround sound format that supports height channels, which means sound can. In this case, you are missing out on the highest. Learn more about our approach to product reviews here. Uncompressed audio will be much higher quality than compressed audio. So, you have nice Dolby Atmos Surround Sound setup, but you only watch content via streaming services. Note that this is all surround sound was in the late 80’s & early 90’s. Matrixed means a computer algorithm is using the sound information from fewer channels to expand and essentially make an “educated guess” about the surround channels.

Dolby Pro Logic IIz = 2.0 or 5.1 to 5.1 +heightĭiscrete means each channel was designed specifically to carry specific sounds by the studio. Dolby Pro Logic IIx = 2.0 or 5.1 to 7.1 Dolby Atmos or DTS:X = 3D surround sound, uncompressed audio. Dolby TrueHD or DTS-MasterHD = 5.1 or 7.1 Dolby Digital EX or DTS-ES Discrete = 6.1ĭiscrete or “True” surround sound w/uncompressed audio: If it doesn’t say “Dolby atmos” on the case or in the audio menu, then Dolby surround is as close to atmos as you will get for that movie.ĭiscrete or “True” surround sound w/compressed audio: The maximum bit rates that Dolby Digital can support for DVD Video and DVD. However, the 640kbits/s is only applicable to Blu-Ray discs. Dolby digital compresses 5.1ch digital audio data down to a raw bit rate of 640 kilobits per second (kbps). Note however that the Blu-ray has to have been encoded in Dolby atmos for your receiver to play it. The main difference between DTS and Dolby Digital is seen in the bit rates and compression levels.

It takes a source that has fewer channels and expands it using algorithms to approximate surround sound with all of your speakers, including the height channels. Dolby Digital is a 5.1 discrete (true surround sound) format, and Dolby surround is a “matrixed” surround sound format. On your second question, if the receiver says “Dolby digital + Dolby surround,” that is not an atmos signal. If you set the Blu-ray player to output the raw signal for the AVR to decode, it will say “Dolby atmos,” because it will see the encoded signal and decode it for the appropriate number of speakers. It will say “multichannel” or “PCM.” However, because only your receiver knows how many atmos channels to decode for, the multichannel from the Blu-ray player is probably not sending the right number of channels. If the Blu-ray player is decoding the audio and sending 5 or more channels of audio to the receiver, then the receiver won’t recognize it as Dolby atmos. edit2: actually it looks like every game listed on the DTS store page used to have an Atmos tag, judging from the list in the Xbox One X Enhanced thread. Check the settings on your Blu-ray player. (along with other Atmos enabled games Gears 5, Metro Exodus and Shadow of the Tomb Raider), and it seems like these games no longer have a 'Dolby Atmos' tag under capabilities.
