Is DTS-HD MA a lossless audio format or not?

[sarge1976]

I was on the BD50 thread and I read somewhere that DTS-HD MA is not a Lossless audio format but indeed a Lossy format, Can someone please straighten this out for me? Also is there a difference between PCM and LPCM or they the same thing? I really didn't know which area to post this question so i appologize ahead of time for those who are gonna give me s**t.

DTS-HD MA is lossless but not uncompressed. PCM and LPCM (the same thing I believe) is uncompressed audio. After decoding of DTS-HD MA, it comes out bit-for-bit the same as uncompressed. So DTS-HD MA is indeed a lossless, but not uncompressed, audio.

Thanks for clearing that up for me,unfortuantly I still can't hear what it sounds like yet because sony has yet to put out firmware for my S500 to accomodate it.

Maybe you're confusing DTS-HD MA with DTS-HD HR?

its just sometimes people just break it down short and say PCM instead of LPCM but they both mean Linear PCM uncompressed audio but yeah DTS HD-Master is not a lossy track
