Im creating a city, and to make it more realistic I want to have stores playing music, but when you leave you can't hear the audio or It's not as loud. I've seen examples of it in some games, and I would like to know how to do it.
Well, first, you'd add a part or make a model of where you want the sound to be played from. Then, you insert the Sound and edit its properties (Such as volume, id, etc.). Those are the 2 steps you'll basically need. The farther away you get from it, the less hear-able it is.
