I want to put a sound effect like this in my documentary, but i cant find where to get it. I have looked all over sound effect sites but no luck... Where can i get it so that it does not have the background music and type writing i just want the blaring sound/bells for my video.

sorry such a newbie question!

Thanks! -rob
