The Obi-wan line replacement works better than I would’ve thought. That’s a change I’ve wanted to make for a long time, and it’s cool to see it work. In my mind, the original line is a lie too far with ROTS in line. All that needs done is filling SFX in that gap where the audio cuts out, and it’s probably perfect.
That gap you mention, in that spot I overlay some room ambience I got from a break in the conversation after Obi-Wan says “and he was a good friend”. I increased the audio gain slightly in hopes that it would match up pretty well. So there is ambient there, but maybe it isn’t perfect since we don’t hear a creeking ‘chest opening up sound’ or something like that.
Yeah it’s almost there, you just need more of that creaking, and/or the sound of Luke working on C-3PO, which we can hear before and after.
