Types of Sound

Dialogue - this is the lines spoken by the characters, can be used to establish character definition.

Voice Over - audio that isn't associated with the screen, is usually the narrator or a character speaking over the screen.

Music (score) - this can be used to heighten the emotion and drama of the scene, establishing atmosphere, time and place. can also be used to announce a character or move the action forward.
Sound Effects - this sound other then dialogue or music. This is background noises, can be used to build suspense.

Diegetic and Non-diegetic sound

diegetic - has a physical origin from either on or off screen, such as a light switch or opening a door.

Non-diegetic - sound that has no direct origin form the film would, such as background music.

Absence of Non-diegetic sound - make the scene or whole movie feel more realistic, can be used to manipulate audiences emotion.

ADR

this is after filming the lines are rerecorded and synced up with the film to make it sound better and clearer.

On/off screen sound

on screen source can be seen in the screen, and off screen that happens off screen.

Direct sound

Sound recorded on location post filming - synchronised sound added after filming.

Contrapuntal sound

Sound that doesn't mirror what the audience is seeing on screen, it contrasts with the mood or tone of the scene.

Parallel sound 

Mirrors what is happening on screen, adding to the mood or tone of the scene.

Exaggerated/Pleonastic sound

Exaggerated sound to heighten the tone, mood, emotion or meaning in a scene.

Foley sound

Recorded sounds after, using different objects to make sound effects for something else.

Analysing

At the start of the scene there is a non-diegetic sound just to set up the scene, there is also dietetic sound like the chewing gum. When Baby puts the song on it acts as a rhythm for the audience to follow as he is flying around the place. The diegetic sounds are the tires screeching across the road, police cars and the helicopter blades, when the shot is from above the car.
