Ripping sounds from Unity Engine

[MadkaT]

Hello friends, I like to rip the voices of the announcer of the game Beat Stomper, I've unpacked the IOS version and I've found that is a Unity game



I've tested a pair of tools like Unity Assets Explorer and a quickbms script, but I can't get a succesful rip, I get stuck with errors and corrupt files  



If someone knows how to do it or can help me, would be nice. Thanks for reading
