How can i increase the sounds volume?

[EMPerror]

Well, simple as that, i have some sounds in my spell triggers, but thanks to the default game music and effects, it's barely hearable, and i want it to be pretty loud. I tried to set the sound volume to more than 100% but i obviously couldn't, then i tried to edit them in the sound editor, but the max is 128, and i looked in gameplay constants and that stuff but i couldn't find anything there.
Will just placing the sound trigger multiple times solve the problem and be efficient?

Maybe edit the sound with a program to be louder?

Well, that sounds like a nice idea but that means i have to import it afterwards, and it would add size to the map...
I guess i would do it if i don't have another choice.
