Sound - and understanding how to use it...

My initial thaughts on using sound in film, my initial thaughts on using sound are that hey use sound in diagetic and non diagetic ways. Diagetic sound is the dialouge, and sounds filmed whilst the film scenes are being filmed. They use non-diagetic sounds to emphisise certian aspects of the film and to make us focus on the dialogue or the sound being emphisised these sounds can range from emphisised sounds or the sound of the wind, guns, explosions. The sound must also be syncronised to the film so they voices match and the sounds are in the correct timing with the film.
