The original production audio can be quite one-dimensional. The focus on set lies on capturing the cleanest dialogue possible. That’s why additional sound design for the production is needed. Hard effects, music and atmospheres have to be implemented to give the audience a better experience to give the audience more information about the time and space where the action takes place and to transport emotional context/set the mood of the scene. Sound, with its non-tangible properties, can extend the story that the picture is telling. It can awaken emotions and instincts in the listener on a subconscious level, opening up a whole new level to experience a production. Sound design elements define and open up the spaces in which the film action takes place. (Where are we? How is it there, Warm? Cold? Peaceful? Menacing? Country or city, indoors/outdoors, season, weather, features.)
The sound effects give the desired emotional character to a specific event or the film’s non-human actors (vehicles, furniture, appliances, animals, creatures). Great sound design can help to bring visual special effects to life (shots, glass crashes, car accidents, etc.). The sound design can make the film appear larger and richer, but it can also create claustrophobic narrowness or oppressive silence.
It is important that you always pay attention to the point of view. (When the performer watches the street below from the window, the traffic and truck driving by can be heard, but at the viewer’s distance). A cut later you can see the truck close to the camera, so the atmosphere must be correspondingly louder.
