welcome to head-fi, BTW.
a mixer pans each track (i.e., insrtument) in the soundstage.
example: drums, bass, and vocals in the middle and guitars and keyboards to the right and left, respectively.
and editor assembles 'takes' onto a master track.
example: a singer might record 5 vocal takes into the multi-track tape. the editor will go in and select the best moments from each track and make a master track that will be used in the mix.
a mastering engineer puts the master mixdown into a tape/disc which all other copies are taken from. a mastering engineer usually EQ's and compresses the mix. why? all the individual tracks will sound different. some will have more bass, or others will be louder than the rest, etc.
a mastering engineer 'homogenizes' the sound of the record.
i'm describing pop and rock recordings here.
classical and jazz recordings are much more straightforward.
