Well, I found that the high Elf hero fits your description:
In the WoodElvesVoicesEn.xcr file, I could not find any “loudness”, but on the contrary in HighElvesVoicesEn.xcr file (the wav. files with the name above).
Perhaps I’m just bringing confusion… Can you please specifically point out which wav. files are you referring to? (I am using DragonUnpacker5)
