Tool for extracting audio from Kid A Mnesia. Uploaded because it might be of use for some other game that I don't know exists.
Warning: I wrote this at 3-6 in the morning. It seems to be perfectly stable and work fine for my usecase. The code isn't great. I cant guarantee it'll work on any other WW/UE4 application.
Drop the folder containing .ubulk and .uexp files on to the executable file. It'll create a new folder called "Exported" with the WEM files in it.
