The final main category of sound effects is ambient sound. This could be the honking of horns in New York City traffic, the sound of birds in the wilderness, or the chopping sounds of knives in a diner kitchen. Ambient sounds are essential for creating atmosphere in a scene. You’ll typically add ambient sounds to a dedicated track. And unlike general sound effects. ambient tracks supplied in stereo or surround sound are ideal since they don’t need to have any specific direction.
