Title: DTS-HD Master Audio 5.1ch -- what does it mean?
Post by: antenna on February 08, 2020, 12:04:22 am
OK, I admit up front, I'm an audio person, not really a video person.

I popped a Blu-ray disc into the player (a Sony Blu-ray player).  When I pressed the Info button, i saw that the audio was encoded via DTS-HD Master Audio 5.1ch  with a 2.2mbps bit rate.  (the rate varied between 2.1 and 2.3, with most of the time on 2.2).

Then I spent some time in various search engines, trying to learn about this DTS-HD thing.  I am now more confused than ever.

The question I am trying to answer ----  is DTS-HD Master Audio 5.1 a lossless format, or not?  The articles I've read online seem to echo between truly lossless, and lossy but so good you can't hear the difference.

For the purpose of reference, ZIP files are lossless, FLAC files are lossless, MP3 files are lossy.

So I ask this august community, what means DTS-HD Master Audio 5.1ch?

If I have a Blu-ray disc that claims that attribution, what am I really listening to?

DTS-HD Master Audio is lossless. Of course that only applies to the compression, whatever they did to the mastering on the disc is up in the air. :)
