I’ve done another audio experiment, and fixed the sync issue with hairy_hen’s 5.1 ROTJ mix. Not that the issue was terribly noticeable to most, but it bugged me enough to do this.
The fixed audio is available in lossy (448k AC3) and lossless (DTS-MA). Contact me if you’re interested.
Fair warning, my audio work is pretty amateurish compared with h_h’s, but I’ve only edited it in two spots for a grand total of less than two seconds altered, and I think it sounds pretty good. YMMV.
