Sound when near an unit

[hdm]

How can I make a sound playing in an area and when units enter that area they listen to the sound ? Using triggers.

Should I use regions ?

U need to use 3D sound for that.
Yes, you use regions to detect when an unit enters the region.

What is 3D Sound ? C'mon tell me everything :/

bump (is this allowed?) I'll give an example: I have four areas and I want to make a music play as theme for each area.

Area 1 - x music
Area 2 - y music
and goes.
