Unofficial High Definition Audio Project Mod
MODA high-definition restoration of Skyrim's orignal voices and music, drawing from the much higher quality PS4 audio as a source.
If in doubt, just go for the 192kbit XWM's, they are a huge improvement over vanilla and do not use the extra 3GB of space needed for the WAV's.
This would still unfortunately require an amount of archiving, as close to a million files in total for all languages (.lip and .wav) is beyond what a torrent can support.
