They too will essentially only have been compressed by one format, Dolby. To PCM by the Xbox they show no signs of compression. A lot of Blu Rays use DTS, however they are almost all lossless DTS, so when they are converted DTS works with a continuing bitrate of 64 to 1536 kbit /s. This way the audio is always compressed using only one format. DTS Neo 2.5 occurs in an audio format with a similar channel division as with Dolby Digital, mostly 5.1. I would choose Dolby, because most (all?) streaming services and most DVDs use Dolby for surround. Dolby Digital sounds good, but DTS delivers more of the clarity and dynamics of the original master soundtrack. The bottom line is Dolby uses more compression than DTS. The best solution is to just pick one and go with it. DTS has generally been 3dB higher in SPL then Dolby recordings according to ,however this was a few years back and things may have changed. Games shouldn't matter, since the audio files could be compressed in different formats and will all be converted to PCM and mixed beforeĪctually, all audio is going to be uncompressed by the Xbox, even DVDs and Blu Rays, and then compressed again into Dolby or DTS if you select Bitstream out.
So use Dolby for streaming, DVDs, and Blu Rays that are encoded in Dolby and DTS for DVDs and Blu Rays encoded in DTS. The best one to use would be the one that is native to the content you are playing. Comparing different codecs based on bitrates is pretty much useless. Does this make DTS better? Not necessarily, it's kind of an apples and oranges comparison. I would assume the Xbox One's Dolby encoder would be 640kbps and the DTS encoder would be 1.5mbps.
