Spatial & tap audio

Sound

Two kinds of audio:

• Spatial — positioned in the world; it gets louder as the visitor approaches and fades with distance.
• Tap — a one-shot sound played when an object is tapped.

Controls

Volume (0–1), loop, and for spatial sound the reference distance (full volume), maximum distance (inaudible beyond) and roll-off (0–5, how quickly it fades).
