I'm curious how other people implemented it

Hi,

I did the programming for this application. Explaining in detail how this was all done would go beyond the scope here. But you are welcome to contact me if you need support.

Not only can we now change the volume of audio depending on distance, we have been able to integrate 3D spatial audio.
Like in this example:

Animated door, clock and spatial audio

Here is an example of an animated door, an animated clock and spatial sound. So turn up the sound to hear the effect [Shapespark example / animated door / clock / spatial audio]

cheers

Simon
