The second component in this is Sound, one of the most main component is Sound. Although film is sometimes thought of as a purely visual art-form it also relies heavily upon audio.

Even in the days of silent film, movies were usually screened with live performances from musicians who would play in time with the action on screen.With the invention of sound, film-makers in the late 1920’s were suddenly able to add a new dimension to their stories.

Actors could be heard to speak, actions could be highlighted with the use of vivid sound effects, and music could be used to give extra emotional life to films.It is now impossible to analyse cinema or to make films without understanding how film-makers use sound.

Different types of film sound include:

Diegetic Sound

The word ‘diegetic’ means to come from the world of a story.

It is sound which the characters on screen can hear and can include sound effects, the sounds made by movements and actions of characters, background noise and spoken dialogue.

Non-diegetic sound

Non-diegetic sound is any sound which does not come directly from the world of the story onscreen.

Traditional film music and voice-over narration are typical examples of non-diegetic sound. The characters in the film are unaware of these sounds, because they don’t exist in their world.

Music and musical scores

Music plays an important role in cinema. It can make action scenes feel more exciting, happy scenes more joyful and frightening scenes more suspenseful. Film scores are non-diegetic and cannot be heard by the characters on screen.

Sometimes, however, films will feature diegetic music. If a character is listening to music playing on a radio or if characters are singing or playing a musical instrument, then that music is diegetic.

Sound effects

A sound effect is any sound, other than speech or music, which has been recorded specifically for the film.Sound effects are usually tied to specific actions on-screen and recorded during post-production to enhance a scene.

A director might, for example, ask their sound designer to record high impact punching sounds to make a fist fight feel more exciting.

Some examples and thorough explanation is done in the following videos about how some of these sound effects are made.

Dialogue

The term dialogue simply means the words that are spoken by the characters on screen. The amount of dialogue in any given film can vary. An action film may have very little spoken dialogue but a character based drama may have a lot.

For film-makers it is important that dialogue is always well recorded and clearly audible.It’s also important to never used dialogue if the story information being discussed can be shown visually.

Foley sound

Foley is the word used to describe replacement sounds recorded in post-production. Foley artists can also enhance or replace an original sound – if a character’s footsteps were not loud enough they might record the sound of their own footsteps and have that audio inserted into the film instead.

Sound bridge

A sound bridge is a technique in which the sound from a previous scene carries over into the opening of the next one.

In a horror movie, if one scene ended with a character screaming, the director might use a sound bridge to have that scream extend into the opening of the next scene.

A sound bridge can also be used to have audio from the next scene begin before the film-maker has cut to it.

Wild track

The term ‘wild track’ refers to sound that is recorded during a film shoot, but separately from the main production audio and without any accompanying film footage being shot.

Examples of wild track might include:

• recording a loud scream which might be heard off-screen during a scene
• re-recording sections of dialogue which may not have been recorded clearly during the day’s filming

The most common use of wild track is to capture ‘room noise’ or ‘atmos’ which is short for atmosphere.

Atmos is the background noise which can still be heard in a room or location even when no-one is speaking.

Recording a minute or more of this noise allows film-makers to edit audio more effectively by using that background track to cover gaps which might otherwise be noticeable.
