Environment Sound Paint
writes the ambient sound enum stored in landscape cells. Activating it temporarily switches the cell-attribute overlay to sound visualization.

The brush supports Circle/Triangle shape, size, proportions and rotation. Choose the target sound, then restrict painting by:
Ocean
Coast
Lake
River
Slow waves
Fast waves
Splash
Wind
Birds
Forest
Jungle
Desert.
The exact list displayed by the application comes from the LND cell sound enumeration available at runtime.
