Neo:6 music should have the parameters (as does PLII Music).

I don't like the extraction process performed by DTS's algorithms at all. I even apply PLIIx to 5.1 DTS tracks for my surround back.

Dolby does the ambiance extraction in very logical way, and patented the process. So DTS searching for their own routine had to come up with something else. To my ears it is much less natural.
