Sorry for the noob question but I'm not 100% sure what Cinema DTS actually is and it seems to be regarded as the best type of soundtrack.
I assume it's the DTS soundtrack used in the cinema but then that makes me wonder why it isn't used for the home release of movies.
And then I wonder how you guys come about these tracks.
Thanks in advance.
Yep it's the DTS track that ran in the cinemas. The home releases don't have it (often) because those are far-field (far away from loudspeakers I think) mixes, and for the home releases they make near-field mixes. That's my basic understanding of it.
How to come about them ... here and there. lol Sometimes they're on ebay too.
Your assumption is correct.
The theatrical soundtracks are not used on home theater equipment because the mixes are meant for large cinemas with distant speakers. This is called a far field mix. I’m grossly simplifying this but you get the point.
Home mixes are called near field mixes since the speakers are in general smaller and closer.
On fanres we like the harder far field mixes, hence us chasing ld and cinema DTS tracks.
As to where to get them you just have to know the right people.
Edit: Tom beat me to it
Also Cinema DTS can refer to the codec used by the theatrical format (APT-X100). 'Domestic' DTS as debuted on Laserdisc uses Coherent Acoustics encoding.
In theory the same master would have been used by each of the then 'Big 3' digital formats (Dolby Digital AC-3, DTS and SDDS). Of the 3 the Cinema DTS CD-ROMS are the easiest to stumble upon and to decode for home use, AC-3 and SDDS basically require cinema equipment to get them off the prints.
Some blus/UHDs do have the theatrical far-field mixes, Criterion's The Game and the Nolan 4K remasters all make a point of including the original mixes
