That is true, too. And at a minimal, you could just hear the sounds of the ocean, maybe they could drown out the overwhelming sounds of Plutt and Teedo.
I think it is just a matter of experimenting until you hit something that feels right.
Also, not as relevant, we’ve talked about this before, but I like the idea of the Force whispers guiding Rey to the tree. I kind of feel something like this could’ve also been used in TFA at one point or two, to help get the idea that the Force is actively pushing her onto this destiny, which would also help explain her resistance to accept it. I think it also would give another explanation for Rey’s quickly growing abilities. The Force literally will have awakened, and it almost becomes a character of its own. The Force voices could be unknown like the whispers, or elements of Obi-Wan, Yoda, and Qui-Gon dialogue could be used and distorted somewhat. But I also like the sound of the female voice used in TLJ, and if you kept it female you could argue that it is Rey’s “inner Force” as well.
