Corrin's Wide Use 4 line ("mmm-hmm") had a weird blip. Not sure if it's always there or due to the audio converting software. After some trial and error, I think I managed to remove it. The voice file on Google Drive is the original one, with the blip.

Most of Ephraim's voices are probably not used. The Ephraim screenshot is not from the game.
