If you want to implement a sense of localization for environmental sounds such as insects and birds, you can do so by placing randomly played sounds all over the map.
The Soundscape plugin allows you to generate random sounds around the player, creating an environment with a sense of localization.
This page introduces how to randomly play bird sounds centered on the player when the player enters a specific TriggerVolume.
