For those with audio expertise what's the best way of going about doing a comparison? Would like to start comparing versions, but definitely sure I don't have the ear for it. (listened to too much noise) But want to give it a shot. Is it best to put one ear as one mix and a second in the other ear. was considering playing short spurts of 2-4 versions listening and going off the lists i've accumulated. problem i'm having with the sources on hand is they're all different frame rate/speeds, the PAL vs NTSC thing. Also getting more familiar with the changes and when they occurred. Would like to compare several of the 80s versions with the 97 SE. then do a straight 2004 / 97 comparison as that seems to be when the most changes were made. Getting the sense that much of the changes thru the 93 are flipping between the 77 35mm stereo and 35mm mono changes.

Also considering putting them into Soundtrack pro so can visual watch the wave forms which might help spot things.
