IRENE (technology)
IRENE (''Image, Reconstruct, Erase Noise, Etc.'') is a digital imaging technology designed to recover analog audio stored on fragile or deteriorating phonograph cylinders, records, and other grooved audio media. It is in use by several archives and preservation institutions in the United States seeking to preserve and digitize historical audio. History The technology was developed at Lawrence Berkeley National Laboratory by Carl Haber and Vitaliy Fadeyev and was announced in a publication of the '' Journal of the Audio Engineering Society'' in 2003.Vitaliy Fadeyev and Carl Haber, ''Reconstruction of Mechanically Recorded Sound by Image Processing''. ''Journal of the Audio Engineering Society'', 2003.PDF It grew out of Haber's research in particle physics; in the 1990s, he had worked on Higgs boson detection experiments, and realized that the cameras he was using to set the detectors could also be used for detailed imaging of grooved audio recordings. The name IRENE is a bac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Imaging
Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing and display of such images. A key advantage of a digital image, versus an analog image such as a film photograph, is the ability to digitally propagate copies of the original subject indefinitely without any loss of image quality. Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. In all classes of digital imaging, the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image. For example, the medium of visible light allows digital photog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeast Document Conservation Center
The Northeast Document Conservation Center (NEDCC) was founded in 1973. It is the first non-profit conservation center in the United States to specialize in the preservation of paper-based library and archival materials. NEDCC was initiated by the state librarians of the six New England states, who agreed to cooperate to provide services to non-profit institutions in the region. It was established with start-up funds from the Council on Library Resources, the New England Library Board, and other donors. From 1973 to 1980, the Center functioned as an arm of the New England Library Board. In 1980, it incorporated as a private, non-profit organization, providing services nationally. NEDCC performs book conservation, paper conservation, photograph conservation, Asian paintings conservation, collections surveys, digitization, and audio preservation with the IRENE Irene is a name derived from εἰρήνη (eirēnē), Greek for "peace".

Wax Cylinder
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their heyday (c. 1896–1916), 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. Early development In December 1877, Thomas Edison and his team invented the phonograph using a thin sheet of tin foil wrapped around a hand-cranked, grooved metal cylinder. Tin foil was not a practical recording medium for either commercial or ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edison Company
The Edison Manufacturing Company, originally registered as under the name of the United Edison Manufacturing Company and often known as simply the Edison Company, was organized by scientist / inventor and entrepreneur, Thomas A. Edison (1847–1931), and incorporated in New York City in May 1889. It succeeded the earlier Edison United Manufacturing Company, founded in 1886 as a sales agency for the old Edison Lamp Company (forerunner of the modern General Electric Company), Edison Machine Works, and Bergmann & Company, which made electric lighting fixtures, bulbs, sockets, and other accessories. In April 1894, the Edison laboratory's new invention of the Kinetoscope motion pictures / filming process and cameras operation, which was about to be commercialized, was brought under the Edison Company umbrella. Six years later in 1900, the United Edison Manufacturing Company was evidently succeeded by the New Jersey–incorporated of the reorganized Edison Manufacturing Company. The c ...

Alexander Graham Bell
Alexander Graham Bell (; born Alexander Bell; March 3, 1847 – August 2, 1922) was a Scottish-born Canadian Americans, Canadian-American inventor, scientist, and engineer who is credited with patenting the first practical telephone. He also co-founded the AT&T Corporation, American Telephone and Telegraph Company (AT&T) in 1885. Alexander Melville Bell, Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices, which eventually culminated in his being awarded the first United States patent law, U.S. patent for the telephone, on March 7, 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Many other inventions marked Bell's later life, including ground-breaking work in Free-space optical commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volta Laboratory
The Volta Laboratory (also known as the Alexander Graham Bell Laboratory, the Bell Carriage House and the Bell Laboratory) and the Volta Bureau were created in Georgetown neighborhood of Washington, D.C., by Alexander Graham Bell. The Volta Laboratory was founded in 1880–1881 with Charles Sumner Tainter and Bell's cousin, Chichester Bell, for the research and development of telecommunication, phonograph and other technologies. Using funds generated by the Volta Laboratory, Bell later founded the Volta Bureau in 1887 "for the increase and diffusion of knowledge relating to the deaf", and merged with the American Association for the Promotion and Teaching of Speech to the Deaf (AAPTSD) in 1908. It was renamed as the Alexander Graham Bell Association for the Deaf in 1956 and then the Alexander Graham Bell Association for the Deaf and Hard of Hearing in 1999.

Au Clair De La Lune
"" (, ) is a French Folk music, folk song of the 18th century. Its composer and lyricist are unknown. Its simple melody () is commonly taught to beginners learning an instrument. Lyrics The song appears as early as 1820 i''Les Voitures Verseés'' with only the first verse. Four verses were later re-published in the 1858 compilation ''Chants et Chansons populaires de la France''. In the 1870 compilation ''Chansons et Rondes Enfantines'', only the first two verses of the original four were retained. Some sources report that "plume" (pen) was originally "lume" (an old word for "light" or "lamp"), which makes more sense of the song’s contextual framework. Much of the lyrics have sexual innuendos. In music Muzio Clementi's Op 48 is a Fantasia (musical form), fantasia on the tune A set of variations on the tune appears in François-Adrien Boieldieu, Boieldieu's opera Les voitures versées, Les voitures versees French composer Ferdinand Hérold wrote a set of variations for ...

Édouard-Léon Scott De Martinville
Édouard-Léon Scott de Martinville (; 25 April 1817 – 26 April 1879) was a French printer, bookseller and inventor. He invented the earliest known sound recording device, the phonautograph, which was patented in France on 25 March 1857. Early years As a printer by trade, he was able to read accounts of the latest scientific discoveries and became an inventor. Scott de Martinville was interested in recording the sound of human speech in a way similar to that achieved by the then-new technology of photography for light and image. He hoped for a form of stenography that could record the whole of a conversation without any omissions. His earliest interest was in an improved form of stenography, and he was the author of several papers on shorthand and a history of the subject (1849). He was married twice and had six children. Phonautograph From 1853, he became fascinated in a mechanical means of transcribing vocal sounds. While proofreading some engravings for a physics te ...

Lacquer Disc
An acetate disc (also known as a ''lacquer'', ''test acetate'', ''dubplate'', or ''transcription disc'') is a type of phonograph record generally used from the 1930s to the late 1950s for recording and broadcast purposes. Despite their name, "acetate" discs do not contain any acetate. Lacquer-coated discs are used for the production of records. Unlike ordinary vinyl records, which are quickly formed from lumps of plastic by a mass-production molding process, a lacquer master or acetate (instantaneous record) is created by using a recording lathe to cut an audio-signal-modulated groove into its surface – a sequential operation requiring expensive, delicate equipment and expert skill for good results. In addition to their use in the creation of masters, lacquers were widely used for many purposes before magnetic tape recorders became common, and in the modern era they are used by dance music DJs. They were used in radio broadcasting to archive live broadcasts, pre-record local p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
