decription of sound in film and in TV

1. Sound in TV and Film
Abdoulmanane Ayeva
Sound-on-film refers to a class of sound film processes where
the sound accompanying picture is physically recorded onto
photographic film, usually, but not always, the same strip of
film carrying the picture. Sound-on-film processes can either
record an analog sound track or digital sound track, and may
record the signal either optically or magnetically

2. Dialogue (speech) Sound
Dialogue authenticates the speaker as
an individual or a real person rather than
the imaginary creation of a story teller.
As is the case with stage drama,
dialogue serves to tell the story and
expresses feelings and motivations of
characters as well.

3. Diegetic-Non Diegetic
Sound
Sound whose source is visible on the screen or
whose source is implied to be present by the action
of the film:
1. voices of characters
2. sounds made by objects in the story
music represented as coming from instruments in
the story space ( = source music)
Another term for diegetic sound is actual 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
mood music
Non-diegetic sound is represented as coming from the
a source outside story space.

4. Ambient Sound
Background music is used to add
emotion and rhythm to a film.
Usually not meant to be
noticeable, it often provides a
tone or an emotional attitude
toward the story and/or the
characters epicted. In addition,
background music often
foreshadows a change in mood.
For example, dissonant music
may be used in film to indicate an
approaching (but not yet visible)
menace or disaster.
