Sound

Sound:
Direct sound: Sounds which are made on the set and are kept within the film for effects of realism.

Studio sound: Sound recorded in the studio to improve the quality and also to remove unwanted sounds that may have been picked up in the filming.

Music: The music within a scene helps the scene pick up a certain pace or allows the audience to understand the emotions within the scene. A slow song may show strong upsetting emotions whereas a fast piece of music is more likely to show a happy excited time.

Silence: This can also be used to have the same effect as music by creating a tense atmosphere but also the silence can cause an un-nerving scene leaving the audience clueless of what is to come next.

Sound perspective: The impression of distance in sound usually created through the use of selective sound.

Sound bridge: Adding to continuity through a scene with music linking the events within a scene together.
Commentary: Usually a voice of one the characters saying something which is unheard by other characters only giving the audience direction of the events happening.

Sound effects: Any sound that is not narration or music.

Dubbed dialogue: Post-recording the voice-track in the studio, the actors matching their words to the on-screen lip movements.

Parallel sound: Sound which match the actions or pace on screen.
