Soundscapes are a type of audio asset used to add ambience to maps. And unlike in Source 1 and other Source 2 games you don't have to edit text files to make them in S&box.
Within the Assets Browser window 'Right Click' > 'New Soundscape' then save the asset.
from within the inspector, you can add the following
- Looped Sounds - Sounds that loop.
- Sting Sounds - Sounds that repeat occasionally.
Within hammer use the Entity tool ( ⇧ shift + e ) to search for the snd_soundscape entity and place it somewhere in your map.
In your object properties window set a soundscape asset to use and specify a radius.
Note: the radius can also be changed in any of the 2D Views by manipulating the helpers
Compile your map and see your soundscape in action!
