Fidelity refers to the extent to which the sound is faithful to the source as the audience conceive it. In the film “She’s on Duty”, what we see is also what we expect to hear and this makes the action movie realistic, credible and intense. In the scenes like, No-young swiftly driving the motorbike we can hear piercing sound of the engine, this made the audience feel the intense or the speedy motorbike. The scene also where the “tik-tak” of the clock was amplified gives us cues to look at the watch and lead us to its depth meaning, where Jane did not throw it and instead she fix and used it. Another scene that prove fidelity is when the Jane and No-young were talking and he ask her what is she reading a bell suddenly cling and that help her answer his question.

All told, the film has a good match between the views, the images or the action and its sound that complement both of the audience senses that made the film very convincing, accurate and lifelike action film. The viewer takes the sound to be coming from its source in the digenetic world of film, then is faithful, regardless of its actual source in production.
