It was composed by very ingenious composer Stephane Picq and while digging you the original files I figured he did a remaster with the original music advisor, art director and producer for the album: Philippe Ulrich

it seems many people were super-touched by this soundtrack, and is indeed a masterpiece on its own. adding much to the atmosphere of the game.
this Sign of the Worm track most definitely still easily gives chills, and Im amazed it was not extensively remixed through the years.

I'm also amazed they didnt take it for any of the movies, as this is super cinematic-like composition, and very distinctive. https://stphanepicq.bandcamp.com/track/spice-op-ra-2024-rema...
Wasn't it Frank Klepacki that composed the music for Dune 2.
Stephane Picq worked with Cryo interactive for the first Dune game.
Wrong composer, but I very recently managed to reverse engineer the music driver for Dune (or two out of four, at least).
Here's the AdLib/SoundBlaster Pro version of the track Morning played by a reverse engineered driver, rendered by nukeykt's Nuked-OPL3.
