includes the availability of visual images in theater, television, cinema, and other forms of art for the blind, visually impaired or other visually impaired. This is a storytelling service (provided at no additional cost) that attempts to describe what a sighted person takes for granted - those images that a blind or visually impaired person could previously only perceive through a whisper away from a sighted companion.
In cinemas, museums and television, film and video presentations, audio description is a commentary and narrative that guides the listener through the presentation with concise and objective descriptions of actions, characters, scene changes, text on the screen, new scenes, environments, clothing, body language and other visual content.
Narration can be added to the audio track to describe important visual details that cannot be understood from the main soundtrack alone. The audio description complements the normal audio track in the program. Audio description is usually added during existing pauses in dialogue.
