i am making a lexus lc500 sound mod and i decided to use the pariah sound as a base (i replaced engine accel, decel etc...) but when i try to import open formats in openiv it says Invalid RIFF/WAVE file, any way to fix it, or did my 30mins of work go to waste?

So, i was trying to make my own mod, replace Franklin's phone with a Samsung Galaxy S20, but when i replace the model in OpenIV i cant open it, i have a few textures but i have no app to put them, i really want to make a mod and upload it, but since i am just trying for the first time without videos and i could not find anything that could help, only opposite of what i need
