Uh, I started working on the 5th movie with bluray audio. Has its problems in each language I have but so far I'd guesstimate 50% of sound effects are reduced... Unfortunately not much luck with voices...
Edit:
5th: Done.
4th: Working on it. I'm not as optimistic as I was on the 5th - quite demotivated actually. Audio keeps desyncing between languages, mixed slightly differently and don't show results as good as the 5th. Also glitches. EH. Hopefully the 3rd one is more like the 5th. Done
3rd: Similar to the last two. Some tracks should have ~reduced SFX but unfortunately this one had the most raw audio in the center channel of all the movies, I think. I also skipped one or two tracks in the previous rip. I assumed RAOH when they weren't in fact RAOH. Done
2nd&1st: After a break but I can already tell you these 2 won't be any different to the previous rips unlike the last 3 movies.
