You don't have one at all, you need to buy it to use it.

lets say i get a kiai
how do i get sound onto it
ik it involves .wav(no idea what that is )
but how do i get a piece of audio from a video into a file (and where would it be)
basically
I need to know everything about sound stuff

Click edit on the sound -> click upload file -> pick an audio filee that's 4.99 seconds or less. -> click upload and it should upload the sound.

Getting the sound.
(I would tell you my method but it's not the easiest to follow). Wait for Neko.

Click Edit Sound?
Where
i dont understand anything about this

How do I use the findsounds.com thing to find things like "Surprise Mothafucka"?
I dunno what to search to get the funny things.
Halp!

I will post in more depth with screen shots, hold on.
@Skype use youtube and youtube convertor.

I dont know whats hard about this at all

open up whatever you want to use and record it with an audio recorder and than change that file to .wav and upload it to your kiai/hit/win sound

but the quality is lower if u record it

Kiai doesn't load properly ingame.

Instead makes a BZZT sound instead of "All thats left is a window to my soul COME AND GET IT!"

I upload it and at the top a red cross appears (the normal one) with an (error?) message "Please upload a sound". This is the sound I am using, I am pretty sure I converted to .wav, although I am wondering if my computer converted back into it's original format when I downloaded it maybe? Could the sound be too short maybe?
