Dump Audio Not working correctly

[Waka Flocka]

Hello guys i want to rip some sounds from my game like the voices and things like that. But i have a problem i enabled the Dump Audio and played the game once done. I navigated to my dolphin folder here's the path > Waka Flocka\Documents\Dolphin Emulator\Dump\Audio and there is 1 file it basically just records the sound watever i do. Thats not what i want shouldn't it just extract all the sounds from the games like all the voices instead of just a file recording the sound as you go how do i fix this someone please help.
