Thanks for the lengthy feedback, MalaStrana. I am most likely going to release a 5.1 version with a higher compression rate, and could also fix some of the issues you’ve brought up. I have a sound engineer friend who’s going to have a crack at matching Vaders dubbed lines…I agree it’s not perfect.
Maybe it could be possible to retrieve Vader’s lines from Rebels which are from the exact same “JEJ’s voice age” era ?
Another aspect that appears to be missing from the Rogue One Vader audio that is a hallmark of the ANH voice is the vibration. RO has the mechanized microphone sound of being in the helmet, but the vibration in his voice is missing.
