I just wonder what can be done about the tinny quality of the dialogue. I feel that ages the film the most in comparison with the others. In Empire and Jedi, you can feel Vader’s voice in the room, but in Star Wars it’s not so much. Ady did some good work on his voice if I remember, but everyone else still sounded like they were speaking into a can.
EQ might help a bit, but I don’t know if that would remove the tinny. Some might be tempted to add reverb, but instead of putting the toothpaste back in the tube, that’s just squeezing out more toothpaste.
I think it is the difference between on set audio versus ADR. Or it could just be changes in technology. Even though the on set audio does sound tinny, I always felt it made everything feel/ sound more realistic. There was an editor on this site, I think it was snooker, adding more of the “room noise” to the prequels.
