I've recently been investigating the differences between home audio playback and the way a DTS CD-ROM is decoded on the equipment of a movie theater; specifically, to find the best possible method of deriving the LFE signal that is embedded in the surround channels.

I think I'm very close to getting it right, since I've been able to get the DTS version of The Empire Strikes Back to sound extremely similar to the Dolby Digital version from the 1997 laserdisc. At this point it's mostly a matter of how to apply what I've done (using Pro Tools and iZotope Ozone 5) to settings that will work in other software.
