Sound

Diegetic sound

Sound whose source is visible on the screen or whose source is implied to be present by the action of the film:
.voices of characters
.sounds made by objects in the story
.music represented as coming from instruments in the story space ( source music)

Digetic sound can be either on screen or off screen

Non-diegetic sound

Sound whose source is neither visible on the screen nor has been implied to be present in the action:

.narrator's commentary
.sound effects which is added for the dramatic effect
music

Non-diegetic sound is represented as coming from the a source outside story space.


Synchronous sounds

sounds which are synchronized or matched with what is viewed. For example:
If the film portrays a character playing the piano, the sounds of the piano are projected.

Asynchronous sound effects

these do not match with a visible source of the sound on screen. Such sounds are included so as to provide an appropriate emotional nuance, and they may also add to the realism of the flim. Eg:
A film maker might opt to include the background sound of an ambulance's siren while the foreground sound and image portrays an arguing couple.

Sound Motif

A sound effect or combination of sound effects that are associated with a particular character, setting, situation or idea through the film. The sound motifs condition the audience emotionally for the intervention, arrival, or actions of a particular character.

Sound bridge

Adding to continuity through sound, by running sound (narration, dialogue or music) from one shot across a cut to another shot to make the action seem uninterrupted.

Voice Over

The term voice-over refers to a production technique where a non-diagetic voice is broadcast live or pre-recorded in radio, television, film, theater and/or presentation.[1] The voice-over may be spoken by someone who also appears on-screen in other segments or it may be performed by a specialist voice actor. Voice-over is also commonly referred to as "off camera" commentary.

Mode of adress

Modes of address can be defined as the ways in which relations between addresser and addressee are constructed in a text. In order to communicate, a producer of any text must make some assumptions about an intended audience; reflections of such assumptions may be discerned in the text (advertisements offer particularly clear examples of this).

Direct adress

A direct address is the name of the person who is being directly spoken to

Sound Mixing

The combination, during the phase of postproduction, of three different categories of film sound-dialogue, sound effects, and music.

Sound perspective

Sound perspective refers to the apparent distance of a sound. Clues to the distance of the source include the volume of the sound, the balance with other sounds, the frequency range (high frequencies may be lost at a distance), and the amount of echo and reverberation.

Dialogue

In a dialogue scene, a constant sound perspective, despite picture cuts, helps maintain continuity

Soundtrack

soundtrack is a contraction of "sound track" and is an audio recording created or used in fim produtcion or post production. Initially the dialogue, sound effects, and music in a film each has its own separate track and these are mixed together to make what is called the composite track, which is heard in the film.

Film score

A film score is a broad term referring to the music in a film which is generally categorically separated from songs used within a film. The term film score is frequently synonymous with film soundtrack, though a soundtrack may also include the songs used in the film while the score does not. A score is sometimes written specifically to accompany a film, but may also be compiled from previously written musical compositions.

Incidental Music

Incidental music is music in a play, television program, radio program, video game, film or some other form not primarily musical. The term is less frequently applied to film music, with such music being referred to instead as the "film score" or "soundtrack."Incidental music is often "background" music, and adds atmosphere to the action.
