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 (e.g., the CALM Act in the United States and the EBU R 128 loudness protocol in Europe).
The different names of this profession are both based on the fact that the mixer is not mixing a live performance to a live audience nor recording live on a set. That is, the mixer is re-recording sound already recorded elsewhere (the basis of the North American name) after passing it through mixing equipment such as a digital audio workstation and may dub in additional sounds in the process (the basis of the European name). While mixing can be performed in a recording studio or home office, a full-size mixing stage or dubbing stage is used for feature films intended for release to movie theaters in order to help the mixer envision how the final mix will be heard in such large spaces.
During production or earlier parts of post-production, sound editors, sound designers, sound engineers, production sound mixers and/or music editors assemble the tracks that become raw materials for the re-recording mixer to work with. Those tracks in turn originate with sounds created by professional musicians, singers, actors, or Foley artists.
The first part of the traditional re-recording process is called the "premix." In the dialog premix the re-recording mixer does preliminary processing, including making initial loudness adjustments, cross-fading, and reducing environmental noise or spill that the on-set microphone picked up. In most instances, audio restoration software may be employed. For film or television productions, they may add a temporary/permanent music soundtrack that will have been prepared by the music editor, then the resulting work will be previewed by test audiences, and then the film or television program is re-cut and the soundtrack must be mixed again. Re-recording mixer may also augment or minimize audience reactions for television programs recorded in front of a studio audience. In some cases, a laugh track may augment these reactions.
During the "final mix" the re-recording/dubbing mixers, guided by the director or producer, must make creative decisions from moment to moment in each scene about how loud each major sound element (dialog, sound effects, laugh track and music) should be relative to each other. They also modify individual sounds when desired by adjusting their loudness and spectral content and by adding artificial reverberation. They can insert sounds into a three-dimensional space of the listening environment for a variety of venues and release formats: movie theaters, home theater systems, etc. that have stereo and multi-channel (5.1, 7.1, etc.) surround sound systems. Today, films may be mixed in 'object-based' audio formats such as Dolby Atmos, which adds height channels and metadata to allow for real-time rendering of audio objects in a three-dimensional coordinate space.
Dubbing is a post-production process used in filmmaking and video production, often in concert with sound design, in which additional or supplementary recordings (doubles) are lip-synced and "mixed" with original production sound to create the finished soundtrack.
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.
Audio mixing is the process by which multiple sounds are combined into one or more audio 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 principal photography 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 mixing console or mixing desk is an electronic device for mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds. Mixers may control analog or digital signals. The modified signals are summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded.
A laugh track is an audio recording consisting of laughter usually used as a separate soundtrack for comedy productions. The laugh track may contain live audience reactions or artificial laughter made to be inserted into the show, or a combination of the two. The use of canned laughter to "sweeten" the laugh track was pioneered by American sound engineer Charles "Charley" Douglass.
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 soundtracks 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.
James K. A. Guthrie is an English recording engineer and record producer best known for his work with the progressive rock band Pink Floyd serving as a producer and engineer for the band since 1978. He is the owner and operator of das boot recording in Lake Tahoe, California. Married to Melissa Kathryn (Braun) Guthrie and parent of two cats, Bert & Jack. Original music and scoring.
Re-recording is the process by which the audio track of a film or video production is created. An Audio re-recording is often called a re-recording of music. As sound elements are mixed and combined the process necessitates "re-recording" all of the audio elements, such as dialogue, music, sound effects, by the sound re-recording mixer(s) to achieve the desired result, which is the final soundtrack that the audience hears when the finished film is played.
The Conch Awards recognise UK companies and individuals who have made outstanding contributions in the field of audio post production.
James Graham Stewart was an American pioneer in the field of sound recording and re-recording. His career spanned more than five decades (1928–1980), during which he made substantial contributions to the evolution of the art and science of film and television sound.
An audio engineer helps to produce a recording or a live performance, balancing and adjusting sound sources using equalization, dynamics processing and audio effects, mixing, reproduction, and reinforcement of sound. Audio engineers work on the "technical aspect of recording—the placing of microphones, pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer…"
In sound recording and reproduction, audio mixing is the process of optimizing and combining multitrack recordings into a final mono, stereo or surround sound product. In the process of combining the separate tracks, their relative levels are adjusted and balanced and various processes such as equalization and compression are commonly applied to individual tracks, groups of tracks, and the overall mix. In stereo and surround sound mixing, the placement of the tracks within the stereo field are adjusted and balanced. Audio mixing techniques and approaches vary widely and have a significant influence on the final product.
Bruce Nazarian was an American funk and rock musician, recording artist and music producer from Detroit, Michigan.
A mixing engineer is responsible for combining ("mixing") different sonic elements of an auditory piece into a complete rendition, whether in music, film, or any other content of auditory nature. The finished piece, recorded or live, must achieve a good balance of properties, such as volume, pan positioning, and other effects, while resolving any arising frequency conflicts from various sound sources. These sound sources can comprise the different musical instruments or vocals in a band or orchestra, dialogue or Foley in a film, and more.
In audio production, a stem is a discrete or grouped collection of audio sources mixed together, usually by one person, to be dealt with downstream as one unit. A single stem may be delivered in mono, stereo, or in multiple tracks for surround sound.
