What is Post-Production Sound?

What is Post Production Sound?


Post-production sound in film is made up of Dialogue (DX), Sound Effects (SFX), Backgrounds (BGs), and

Music (MX). Dialogue can be production recordings that are captured on set as well as voiceovers and

ADR (Automated Dialogue Replacement). Sound Effects (SFX) include on-set recordings which are called

production effects as well as sound effects from a library or created on the Foley stage. Backgrounds

(BGs) are stereo sound effects that last for the duration of a scene and help build the ambience of the

film. The final element is Music (MX) which can be score or source. All of these components come

together to create the final soundtrack of the film.

Depending on the scale of the project, the size of the sound editorial team and the division of roles will

vary. These are a few of the many post production sound jobs that you will most likely encounter when

working with the sound department.

● Sound Editor/Designer: They are responsible for creating or finding sounds that enhance

everything that happens in the film. Additionally, make sure the dialogue is audible, all

extraneous noises are removed and the overall loudness is at the proper level for all other

effects to be designed around it. This individual will create a soundtrack that is in line with what

they see on screen and ensure that the director’s vision is executed.

● Composer: They create the original music in the film. USC Thornton School of Music has many

talented composers that are willing to collaborate and score your films.

● Re-Recording Mixer: The re-recording mixer gets the finalized sound edit and is responsible for

making sure the dialogue, sound effects, backgrounds, and music are all cohesively mixed

together. This work usually takes place on a mixing stage that replicates the experience of a

theater. This is the final step in the post production process.
