Sounds

Sounds are a small but important part of a map. If no sounds are playing, the map can feel empty and unsettling. Ambient sounds are automatically muffled if a player is deemed to be indoors.

AmbienceSound

AmbienceSound <list>
Multiple ambient sounds can play at different altitudes.

"AmbienceSound": [
    {
        "Type": "wind", // sound
        "Steps": [
            {
                "Altitude": 0, // Y coordinate
                "Volume": 0.3 // 0.0-1.0
            }
        ]
    }, // add more...
]
