EDIT: I think it was some bizarre encoding issue that happened, re-encoding through FFMPEG with silence removal seems to have fixed it.
I'm having a problem where some of my voice pack WAV files are having extra silence added onto them in-game, and then I get 0 scores due to background noise being picked up and being considered inaccurate to the added silence. They don't exist in the files themselves, I've checked in Audacity. Is this a known issue?
