Pre-Mix (reference) - These are reference tracks that are in their raw form before any type of mixing begins. These tracks are typically include the vocals, instruments, etc without major processing (if any). The product of what the song will soon become is in this stage.
Premasters - These tracks have been mixed down by the mix engineer and are ready to enter the final stage of mastering.
Masters - The final frontier and the icing on the cake. This is where the mixed track is lifted to the next level to create a sound that competes with the major music we all love and appreciate. Notice the difference in clarity, depth, space, and even volume in comparison to the pre-mixed reference track.
