Audio post production is all stages of audio production relating to sound produced and synchronized with moving picture (film, television, or video). It involves sound design, sound effects, Foley, ADR, sound editing, audio mixing, mastering etc.
In filmmaking, audio post production is the creation and manipulation of audio that is synchronized with moving picture. This includes, but is often distinguished from production audio, which is the audio recorded as filming occurs. Most other aspects of audio for moving picture occur during the post production phase, everything done after filming. This also may include sound design or the creation of sound effects, which can occur during pre-production, production, or post production. This applies to television, cinema and commercials. One major aspect of audio post production is the use of automatic dialogue replacement (ADR).
Sometimes the original production audio lacks in performance or quality, and one or more actors work in a sound studio to record some or all of their dialogue from the project. Other elements such as Foley, music and voiceover are also added during post production. [1]
In music, audio post production includes processes such as mixing and mastering. The audio engineering community more commonly refers to these processes as music production.
Reworking and enhancing voice-based media is prevalent in the form of noise reduction and volume normalization. With the emergence of podcasts, audio post production with a focus on vocals has become more common. Sound recording devices with different characteristics and capabilities such as dynamic range has led to increased demand for consistent sound. With many techniques being adjusted specifically for vocal audio, the field is becoming more understood as unique to music production.
A film crew is a group of people, hired by a production company, for the purpose of producing a film or motion picture. The crew is distinguished from the cast, as the cast are understood to be the actors who appear in front of the camera or provide voices for characters in the film. The crew is also separate from the producers, as the producers are the ones who own a portion of either the film studio or the film's intellectual property rights. A film crew is divided into different departments, each of which specializes in a specific aspect of the production. Film crew positions have evolved over the years, spurred by technological change, but many traditional jobs date from the early 20th century and are common across jurisdictions and filmmaking cultures.
A sound effect is an artificially created or enhanced sound, or sound process used to emphasize artistic or other content of films, television shows, live performance, animation, video games, music, or other media. Traditionally, in the twentieth century, they were created with foley. In motion picture and television production, a sound effect is a sound recorded and presented to make a specific storytelling or creative point without the use of dialogue or music. The term often refers to a process applied to a recording, without necessarily referring to the recording itself. In professional motion picture and television production, dialogue, music, and sound effects recordings are treated as separate elements. Dialogue and music recordings are never referred to as sound effects, even though the processes applied to such as reverberation or flanging effects, often are called "sound effects".
A soundtrack is recorded music accompanying and synchronised to the images of a motion picture, drama, book, television program, radio program, or video game; a commercially released soundtrack album of music as featured in the soundtrack of a film, video, or television presentation; or the physical area of a film that contains the synchronised recorded sound.
Audio mixing is the process by which multiple sounds are combined into one or more channels. In the process, a source's volume level, frequency content, dynamics, and panoramic position are manipulated or enhanced. This practical, aesthetic, or otherwise creative treatment is done in order to produce a finished version that is appealing to listeners.
Post-production is part of the process of filmmaking, video production, audio production, and photography. Post-production includes all stages of production occurring after shooting or recording individual program segments.
A production sound mixer, location sound recordist, location sound engineer, or simply sound mixer is the member of a film crew or television crew responsible for recording all sound recording on set during the filmmaking or television production using professional audio equipment, for later inclusion in the finished product, or for reference to be used by the sound designer, sound effects editors, or foley artists. This requires choice and deployment of microphones, choice of recording media, and mixing of audio signals in real time.
A sound editor is a creative professional responsible for selecting and assembling 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. The sound editor works with the supervising sound editor. The supervising sound editor often assigns scenes and reels the sound editor based on the editor's strengths and area of expertise. Sound editing developed out of the need to fix the incomplete, undramatic, or technically inferior sound recordings of early talkies, and over the decades has become a respected filmmaking craft, with sound editors implementing the aesthetic goals of motion picture sound design.
Sound design is the art and practice of creating sound tracks for a variety of needs. It involves specifying, acquiring or creating auditory elements using audio production techniques and tools. It is employed in a variety of disciplines including filmmaking, television production, video game development, theatre, sound recording and reproduction, live performance, sound art, post-production, radio, new media and musical instrument development. Sound design commonly involves performing and editing of previously composed or recorded audio, such as sound effects and dialogue for the purposes of the medium, but it can also involve creating sounds from scratch through synthesizers. A sound designer is one who practices sound design.
The dialogue editor is a type of sound editor who assembles, synchronizes, and edits all the dialogue in a film or television production. Usually, they will use the production tracks: the sound that was recorded on the set. If any of the production tracks are unusable they can be replaced by either alternate production tracks recorded on set or by ADR, automated dialogue replacement, which is recorded after the shoot with the actors watching their performances in a sound studio and rerecording the lines. Large productions may have an ADR editor working under the dialogue editor, but the positions are often combined. The ADR editor or dialogue editor also work with the walla group in films which they are required, providing the background chatter noise in scenes with large crowds, such as parties or restaurants.
A sound stage is a soundproof, large structure, building, or room with large doors and high ceilings, used for the production of theatrical film-making and television productions, usually located on a secured movie or television studio property.
Lip sync or lip synch is a technical term for matching a speaking or singing person's lip movements with sung or spoken vocals.
Filmmaking is the process by which a motion picture is produced. Filmmaking involves a number of complex and discrete stages, starting with an initial story, idea, or commission. It then continues through screenwriting, casting, pre-production, shooting, sound recording, post-production, and screening the finished product before an audience that may result in a film release and an exhibition. Filmmaking occurs in a variety of economic, social, and political contexts around the world. It uses a variety of technologies and cinematic techniques.
Television crew positions are derived from those of film crew, but with several differences.
Motion Picture Sound Editors (M.P.S.E.) is an American honorary society of motion picture sound editors founded in 1953. The society's goals are to educate others about and increase the recognition of the sound editors, show the artistic merit of the soundtracks, and improve the professional relationship of its members. The society is not to be confused with an industry union, such as the I.A.T.S.E. The current president is Mark Lanza.
Audio-to-video synchronization refers to the relative timing of audio (sound) and video (image) parts during creation, post-production (mixing), transmission, reception and play-back processing. AV synchronization can be an issue in television, videoconferencing, or film.
Stem-mixing is a method of mixing audio material based on creating groups of audio tracks and processing them separately prior to combining them into a final master mix. Stems are also sometimes referred to as submixes, subgroups, or buses.
In filmmaking, Foley is the reproduction of everyday sound effects that are added to films, videos, and other media in post-production to enhance audio quality. These reproduced sounds, named after sound-effects artist Jack Foley, can be anything from the swishing of clothing and footsteps to squeaky doors and breaking glass. Foley sounds are used to enhance the auditory experience of the movie. Foley can also be used to cover up unwanted sounds captured on the set of a movie during filming, such as overflying airplanes or passing traffic.
A re-recording mixer in North America, also known as a dubbing mixer in Europe, is a post-production audio engineer who mixes recorded dialogue, sound effects and music to create the final version of a soundtrack for a feature film, television program, or television advertisement. The final mix must achieve a desired sonic balance between its various elements, and must match the director's or sound designer's original vision for the project. For material intended for broadcast, the final mix must also comply with all applicable laws governing sound mixing.
Kantana Group is a production company established in Bangkok, Thailand in 1951 by Pradit and Somsook Kaljaruek. Kantana took its first step from radio dramas to films, television dramas, variety programs, and eventually moved on to become an integrated entertainment company.
Audiography within Indian-style filmmaking, is the audio engineering performed by the sound department of a film or TV production; this includes sound recording, editing, mixing and sound design but excludes musical composition, songwriting and choreography.
