Layering andTexture
A great ambient track is rarely a single recordg. Sound designats layer multiple tracks: a base room tone, a layer of distant traffic, another layer of bird calls, and perhaps a layer of wind. Each layer is adiusted in volume andd frequency to create depte. For a quiet desert scene, you might have a low wind rumble, thee buzz of an insect, anthe faint sound of shifting sand.
