TIMELINE -- DEVELOPMENT OF FILM AND SOUND ON FILM


1870s -- Eadweard Muybridge -- Movement of a horse stop action photography on glass plates. Done with multiple cameras designed so that a horse's foot would trip each shutter.

1882 -- Frenchman Etienne-Jules Marey designed a camera to record 12 separate images on a single strip of film. In 1888 he designed the first flexible film.

1889 -- Eastman Kodak introduces celluoid flexible film base

1888 -- Thomas Alva Edison meets with Edweard Muybidge and purchases 90 of his plates to begin experimenting with moving pictures. His intention was to couple live action with the sound produced by his phonograph.

Late 1880s -- Edison commissions William Kennedy Laurie Dickson to build a film camera. Dickson develops the Kinetograph which coupled recorded images with phonographic sound. The final result in 1892, the peep show penny arcades which were first installed in 1894.
William Kennedy Laurie Dickson conducted many experiments with the Kinetograph. One of the earliest surviving experiments is his film of co-worker Fred Ott's "Sneeze":
         
1895 -- Louis and Auguste Lumiere present the first film projector -- the Cinematographe.

1896 -- Edison produces a film projector developed by Thomas Armat and C. Francis Jenkins and exploited by vaudeville peep show promoters Norman C. Raff and Frank R. Gammon. This projector was called the Vitascope.

April 1896 -- First public movie theatre -- the Theatre Robert Houdin -- operated by magician and photographer Georges Melies in Paris using a modified British projector developed initially by Robert William Paul. Meleis became known for developing the world's first "trick" photography with cut edits and disolves. 1902 he produced Jules Verne's A Trip To The Moon 14 minutes long and three times the length of any previous film. This also demonstrated Melies genius for editing with 30 separate scenes.

1902 -- 1926 : The era of the silent film while inventors including Edison sought to link sound mechanically with moving film images.
1904 -- Frenchman Eugene Lauste records sound onto a piece of photographic film

1907 -- 1913 various fim and sound inventions included the Vivaphone, Synchroscope, the Chronophone, the Cameraphone and the Cinephone. Edison produced the Kinetophone in 1913 -- a "Rube Goldberg" device of belts and pulleys and received boos for his efforts at Keith's Union Square theatre in New York City.

19teens -- Western Electric develops along with Lee DeForest (1906 Audion) a method or recording and reproducing sound electronically on disc. Western Electric Buought the rights to the use of the Audio for amplifying the phonographic sound.

1921 -- DeForest improves the method of recording sound on film and patents a new invention he calls the phonofilm.

September 1925 -- Warner Bros. contracts with the AT&T method of sound with film and releases its first sound with film pictures in 1926 using a system dubbed theVitaphone. Don Juan, released in 1926 was the first film to inlcude music on an amplified sound- track.

October 1927 -- The Jazz Singer featuring Al Jolson is released by Warner Bros. Not an immediate hit in New York, but it gained long-lasting fame when it moved into America's heartland. It was rebooked in 1928 in New York and grossed $100,000 a week.

May 1927 -- Fox Film Corporation works with a new AT&T development -- sound on film. Fox uses this system to produce newsreels which would play prior to feature films at theatres.The first big publicity coups was the flight of Charles Lindbergh across the Atlantic. Also memorable was the capturing of the explosion of the Hindenburg. These newsreel shorts became known as the Movietone News.

May 1928 -- the major film companies (Paramount, Loews/MGM, First National and United Artists) sign with AT&T to produce pictures with sound on film despite the introduction of a competing format developed by RCA.

End of 1920s -- only a few theatres in America's largest cities continued to maintain a house orchestra and organist.

September 1928 -- Warner Bros. releases The Singing Fool -- again starring Al Jolson. Tickets for the first night were $11.00. "Sonny Boy" and "There's a Rainbow 'Round My Shoulder" from the film became the first million selling record of the "talkie" era. The Singing Fool cost $200,000 to produce but drew an unprecedented $5,000,000.

About Audio Engineering

Audio engineering is a skilled trade that deals with the use of machinery and equipment for the recording, mixing and reproduction of sounds. The field draws on many artistic and vocational areas, including electronics, acoustics, psychoacoustics, and music. An audio engineer is proficient with different types of recording media, such as analog tape, digital multitrack recorders and workstations, and computer knowledge. With the advent of the digital age, it is becoming more and more important for the audio engineer to be versed in the understanding of software and hardware integration from synchronization to analog to digital transfers.

Audio engineering concerns the creative and practical aspects of sounds and music, in contrast with the formal engineering discipline known as acoustical engineering. Producer, engineer, mixer Phil Ek has described audio engineering as the "technical aspect of recording—the placing of microphones, the turning of pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer... the nuts and bolts. Many recording engineers also invented new technology, equipment and techniques, to enhance the process and art.
