So what's the difference between them and what is lossless?

redboxcar · 11-18-2008, 04:17 PM

I feel silly but I'd like to know, too... I recognize the difference and the hierarchy based on user comments from all around the format, but in reality I have no clue what each one really means.

PCM = Uncompressed Audio = no distortion, no compression
Dolby True HD = Lossless Audio = no distortion, compressed
DTS-HD MA = Lossless Audio = no distortion, compressed
Dolby Digital = Lossy Audio = distortion, compression
DTS legacy = Lossy Audio = distortion, compression

The only difference between Dolby and DTS is how they compress the files

Well, the other two are supposed to be = to PCM.

PCM
Dolby TrueHD
DTS-HD MA
These are the big three, & ya there supposed to be the same, but it really depends on who is making the audio track...?

So you can see it just comes done to the persons ears, about which one of the three they like the best?
