Sound-on-disc is a class of sound film processes using a phonograph or other disc to record or play back sound in sync with a motion picture. Early sound-on-disc systems used a mechanical interlock with the movie projector, while more recent systems use timecodes.
During the 1920s and early 1930s, films in the United States were subject to censorship by state and city censor boards, which often required cuts of scenes before a film would be licensed for exhibition. While films using the sound-on-film process could accommodate a patch for a requested cut with ease, a film using sound-on-disc would require an expensive retake. [2] If the cost of compliance with a censor board was too high, the film would not be shown in that state or city.
A silent film is a film without synchronized recorded sound. Though silent films convey narrative and emotion visually, various plot elements or key lines of dialogue may, when necessary, be conveyed by the use of inter-title cards.
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips 1.377 ± 0.001 inches (34.976 ± 0.025 mm) wide. The standard image exposure length on 35 mm for movies is four perforations per frame along both edges, which results in 16 frames per foot of film.
A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films took place in Paris in 1900, but decades passed before sound motion pictures became commercially practical. Reliable synchronization was difficult to achieve with the early sound-on-disc systems, and amplification and recording quality were also inadequate. Innovations in sound-on-film led to the first commercial screening of short motion pictures using the technology, which took place in 1923. Before sound-on-film technology became viable, soundtracks for films were commonly played live with organs or pianos.
Phonograph cylinders are the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their heyday, a name which has been passed on to their disc-shaped successor, these hollow cylindrical objects have an audio recording engraved on the outside surface which can be reproduced when they are played on a mechanical cylinder phonograph. The first cylinders were wrapped with tin foil but the improved version made of wax was created a decade later, after which they were commercialized. In the 1910s, the competing disc record system triumphed in the marketplace to become the dominant commercial audio medium.
Edison Records was one of the early record labels that pioneered sound recording and reproduction, and was an important and successful company in the early recording industry.
The Edison Diamond Disc Record is a type of phonograph record marketed by Thomas A. Edison, Inc. on their Edison Record label from 1912 to 1929. They were named Diamond Discs because the matching Edison Disc Phonograph was fitted with a permanent conical diamond stylus for playing them. Diamond Discs were incompatible with lateral-groove disc record players, e.g. the Victor Victrola, the disposable steel needles of which would damage them while extracting hardly any sound. Uniquely, they are just under 1⁄4 in thick.
Vitaphone was a sound film system used for feature films and nearly 1,000 short subjects made by Warner Bros. and its sister studio First National from 1926 to 1931. Vitaphone is the last major analog sound-on-disc system and the only one that was widely used and commercially successful. The soundtrack is not printed on the film, but issued separately on phonograph records. The discs, recorded at 33+1⁄3 rpm and typically 16 inches (41 cm) in diameter, are played on a turntable physically coupled to the projector motor while the film is projected. Its frequency response is 4300 Hz. Many early talkies, such as The Jazz Singer (1927), used the Vitaphone system. The name "Vitaphone" derived from the Latin and Greek words, respectively, for "living" and "sound".
Parental Advisory is a warning label placed on audio recordings that contain explicit content, such as profanity, violence, or sexual content/references. It was introduced by the Recording Industry Association of America (RIAA) in 1987 and adopted by the British Phonographic Industry (BPI) in 2011. The label was first affixed on physical 331⁄3 rpm records, compact discs and cassette tapes, and it has been included on digital listings offered by online music stores. In PAL-region territories, some video games featuring licensed music were affixed with the label in the late 1990s and early 2000s.
A movie projector is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras. Modern movie projectors are specially built video projectors.
Oskar Messter was a German inventor and film tycoon in the early years of cinema. His firm Messter Film was one of the dominant German producers before the rise of UFA, into which it was ultimately merged.
Pathé is a French major film production and distribution company, owning a number of cinema chains through its subsidiary Pathé Cinémas and television networks across Europe.
Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded on photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an analog sound track or digital sound track, and may record the signal either optically or magnetically. Earlier technologies were sound-on-disc, meaning the film's soundtrack would be on a separate phonograph record.
Léon Ernest Gaumont was a French inventor, engineer, and industrialist who was a pioneer of the motion picture industry. He founded the world's oldest operating film studio, Gaumont Film Company, and worked in partnership with Solax Studios.
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording.
The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods:
Optical sound is a means of storing sound recordings on transparent film. Originally developed for military purposes, the technology first saw widespread use in the 1920s as a sound-on-film format for motion pictures. Optical sound eventually superseded all other sound film technologies until the advent of digital sound became the standard in cinema projection booths. Optical sound has also been used for multitrack recording and for creating effects in some musical synthesizers.
A film, also called a movie, motion picture, moving picture, picture, photoplay, or flick—is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, emotions, or atmosphere through the use of moving images that are generally accompanied by sound and other sensory stimulations. The word "cinema" is a shortening of the word "cinematography" and is used to refer to either filmmaking, the film industry, the overall art form, or a movie theater.
The Phonoscène was an antecedent of music video and was regarded by Michel Chion, Noël Burch and Richard Abel as a forerunner of sound film. The first Phonoscènes were presented by Léon Gaumont in 1902 in France. The first official presentation in the United Kingdom took place at Buckingham Palace in 1907. The last phonoscène was presented in 1917.
The Chronophone is an apparatus patented by Léon Gaumont in 1902 to synchronise the Cinématographe (Chrono-Bioscope) with a disc Phonograph (Cyclophone) using a "Conductor" or "Switchboard". This sound-on-disc display was used as an experiment from 1902 to 1910. In January 1911, the industrial exploitation started at the Olympia. Chronophone would show Phonoscènes and films parlants almost every week from 1911 until 1917 at the Gaumont Palace, "the Greatest Cinema Theatre in the World", previously known as the Paris Hippodrome.
The history of film technology traces the development of techniques for the recording, construction and presentation of motion pictures. When the film medium came about in the 19th century, there already was a centuries old tradition of screening moving images through shadow play and the magic lantern that were very popular with audiences in many parts of the world. Especially the magic lantern influenced much of the projection technology, exhibition practices and cultural implementation of film. Between 1825 and 1840, the relevant technologies of stroboscopic animation, photography and stereoscopy were introduced. For much of the rest of the century, many engineers and inventors tried to combine all these new technologies and the much older technique of projection to create a complete illusion or a complete documentation of reality. Colour photography was usually included in these ambitions and the introduction of the phonograph in 1877 seemed to promise the addition of synchronized sound recordings. Between 1887 and 1894, the first successful short cinematographic presentations were established. The biggest popular breakthrough of the technology came in 1895 with the first projected movies that lasted longer than 10 seconds. During the first years after this breakthrough, most motion pictures lasted about 50 seconds, lacked synchronized sound and natural colour, and were mainly exhibited as novelty attractions. In the first decades of the 20th century, movies grew much longer and the medium quickly developed into one of the most important tools of communication and entertainment. The breakthrough of synchronized sound occurred at the end of the 1920s and that of full color motion picture film in the 1930s. By the start of the 21st century, physical film stock was being replaced with digital film technologies at both ends of the production chain by digital image sensors and projectors.
