List of Common Sound-Engineering Terms and Definitions

Mixing -To combine a variety of source audio elements in order to create a finished, cohesive, combined audio track. For music, this is accomplished by creating a sonic balance between all instrumentation within a record.  For film & television, this will be achieved by creating a desired sonic balance between dialog, sound effects, and music. 

Dialogue Editing - assembling, synchronizing, and editing dialogue in a motion picture, television, or video game production.

Sound Editing - To select and assemble  sound recordings  in preparation for the final sound mixing or mastering of a television program, motion picture, video game, or any production involving recorded or synthetic sound.

ADR/Looping- ADR - An acronym that stands for “automated (or additional) dialog replacement,” and refers to the re-recording of dialogue after the filming of picture. ADR is also known as "looping."

Voice-Overs - (more familiarly “VO”) is recorded during the post-production of a film to add scripted dialog over picture. VO is not lip-synched as is ADR, but instead is usually used for exposition.

Foley Recording - A process of adding organic sound effects to film and television soundtracks by performing them in sync with picture. Its main purpose is to replace or enhance production sounds that have been obstructed by noise or are not convincing enough to supplement the visual effect or action.

Production Sound - The capturing of all audio (dialog & effects) on set of any motion picture or television production. I.e Boom Operator - A boom is a long pole upon which a microphoneis mounted to capture dialog and effects during the production of a movie or television program. The length of the pole allows the recordist to work far from the actors and out of the camera's view.

Live Sound - The art of combining and processing a number of audio signals together to create a "mix" that the audience or performers at a live show hear. There can be a variety of different mixes required, depending on the performance requirements. Three types are: Front of House(FOH), which is primarily for the audience; Monitor, which is exclusively for the performer(s); and Recording or Broadcast (cue), for special purposes.
