Sound

 

There Are Two Types of sound:      

Diegetic - Sound is called diegetic when its source is visible or implied in the world of the film. Common diegetic sounds present in most films are:

• Actors speaking to each other (dialogue).
• Sounds originating from any object on the screen, like footsteps and doors opening/closing.
• Music that comes from a sound system or an orchestra.

Non Diegetic - Sound is said to be non-diegetic when its source is not present or implied in the narrative universe. Common instances are:

• Music or score, used to augment emotions.
• Actor’s commentary or narration.
• Any extra sound added for effect.
