PvZ Heroes Downloaded Data Audio?

I'm trying to rip SFX and such from Plants vs Zombies Heroes, however, the base archive where the base data does not have any real sfx. It's Unity powered, so using Perfare's version of Unity Studio should be able to work. I would just like to know how to get the actual archive data that's downloaded through the app. I mean I've seen modders do stuff with the game, but I have no idea how to get the data I need...

Anyone got any ideas? I could really use some help with this.
