How do I get audio to play at a radius to player?

I know there's a recipe for getting this to work but for some reason I cant seem to get it to work. I have a platform game that has something following the player that has a sound attached to it, and the further away from this object I want to audio to go quieter and if your to far away you wont hear the object at all, so how exactly do I make the audio have a hear radius?

Positioned audio needs a play at and a listener object..

Your listener object will most probably be your player sprite and you'll want the audio to play at the object..

more information is in the manual:

you could do it this way or work it out how to from this demo

Or, you can use an invisible sprite and check for collision.

imho, you can make trigger to check every sound, make it loud or quite in set volume
