I've been looking for cool Kaiai sounds, but there's no good websites for free,
anyone know any?

all you need is a 4.9 second sound clip of anything and you can use it

First go to youtube.com find a music that you want as kiai or sound...

then go to youtube-mp3.org and paste the link of the sound/ music you want

once you downloaded it go to mp3cut.net and find your sound when you clicked browse.

Then you select with the blue area when it should start and stop but kiai can only require 5 sec long maximum.

then render it by WAV it important to render with WAV
then click cut, then it should come a download button middle on the cutter thingy. Well thats it All you need to do now is to upload your kiai
