I found this sound effect resource for my mech game, but these sound effects are used in the Gundam series. I know there are some shows and games other than Gundam that use identical sounds.
Is it legal to use them for making my own mobile game apps, if I alter the pitch and do some remixes? I'm making a 'fan-game' or 'mech-inspired' game, but in an original and legitimate way as possible.
