[REQ] I need a sound (UD)

[prozium]

So I need the sound of a whispering when an UD building is summoned. I've been looking all over the world editor and the sound editor and still no luck at all. It's not a building's sound, it's not a unit's sound and I couldng find it in the ambient. You can hear the sound when you summon a building and it sounds like whispering of some kind. I realli need it, cause i want to use it for my windows mobile 6.1 ROM for my phone as a boot sound.
So thanks in advance.
