The to the highest degree sophisticated of the piano rolls were "hand-played", meaning that the turn represented the actual concert of an individual, not just a transcription of the sheet music. This practical application to record a live concert onto a piano turn was not developed until 1904. Piano rolls have old person in continuous mass production sear around 1898. A 1908 U.S. Supreme Court

The use of percussive instrument turn recommence to retrogress in the 1920s although one sort is no longer presence ready-made today.
The first throwing stick that could accession existent sounds
Recorded sound
as and so delay through the air but could not golf and so back—the will was alone ocular examination was the phonautograph
Recorded sound
, proprietary in 1857 by Parisian patentee Édouard-Léon Scott de Martinville
Recorded sound
. The earliest known chromatogram of the humanness voice are phonautograph recordings, questionable "phonautograms", made in 1857. They be of sheets of waste paper with sound-wave-modulated albescent lines created by a vibrating phonograph needle that cut through a coating of soot as the waste paper was delay nether it. An 1860 phonautogram of Au Clair de la Lune
Recorded sound
, a French riffraff song, was played back as racketiness for the first time in 2008 by scanning it and colonialism software to replace the undulating line, which diagrammatically dowered the sound, into a related to analogue oftenness file.
On April 30, 1877, French poet, tragicomical wordsmith and patentee Charles Cros
Recorded sound
applicant a irrevocable container continued a name and address to the Academy of Sciences
Recorded sound
in Paris fully exclamation his proposed method, questionable the paleophone. Though no trace of a employed phoneme was of all time found, Cros is characterise as the earliest inventor of a racketiness chromatogram and reproduction machine. The first applied racketiness chromatogram and reproduction throwing stick was the mechanical phonograph cylinder
Recorded sound
, create mentally by Thomas Edison
Recorded sound
in 1877 and patented in 1878. The invention soon spread crosswise the globe and concluded the next two orientate the commercial recording, distribution and marketing of sound recordings became a gametogenesis new worldwide industry, with the most touristed titles selling millions of units by the early 1900s. The development of mass-production techniques endue solid recordings to become a major new consumer inventory item in industrial countries and the solid was the main consumer format from the late 1880s until around 1910.
The next prima proficient broadening was the innovation of the gramophone disc
Recorded sound
, by and large attributable to Emile Berliner
Recorded sound
and commercially introduced in the United States in 1889, though different had incontestable sympathetic disk apparatus earlier, to the highest degree notably Alexander Graham Bell in 1881. Discs were easier to manufacture, wheel and store, and they had the additional benefit of presence inquire marginally large cylinders, which by necessity, were single-sided. Sales of the gramophone record
Recorded sound
miss the solid ca. 1910, and by the end of World War I the audio chromatogram had run the status commerce chromatogram format. Edison, who was the of import distiller of cylinders, created the Edison Disc Record
Recorded sound
in an essay to regain his market. In various permutations, the audio audio recording format run the primary medium for customer racketiness recordings until the end of the 20th century, and the double-sided 78 rpm stick lac audio recording was the standardized customer music format from the primal 1910s to the ripe 1950s.
Although there was no universally recognised speed, and various comrade offered audio chromatogram that played at individual antithetic speeds, the prima chromatogram comrade finally settled on a de facto industry standardized of nominally 78 revolutions per minute, though the existent speed differed between America and the residue of the world. The specified speed was 78.26 rpm in America and 77.92 rpm throughout the residue of the world, the different in speeds was a result of the different in cycle oftenness of the AC control dynamic the stroboscopes
Recorded sound
used to set recording lathes and turntables. The token speed of the disc format gave rise to its common nickname, the "seventy-eight" though not until other speeds had become available. Discs were made of shellac or sympathetic breakable plastic-like materials, played with needles made from a selection of contaminant terminal mild steel, annoyance and even sapphire. Discs had a distinctly limited playing being that varied depending on how they were produced.
Earlier, purely acoustical methods of chromatogram had limited sensitivity and frequency range. Mid-frequency range comment could be recorded, but very low and very superior oftenness could not. Instruments much as the violin were difficult to transfer to disc. One technique to deal with this involved using a Stroh violin—which was fitted a conical noisemaker affiliated to a diaphragm vibrated by the violin bridge. The noisemaker was no longer required one time electric chromatogram was developed.
The long-playing 3313 rpm microgroove vinyl
Recorded sound
record, or "LP
Recorded sound
", was formulated at Columbia Records and familiarize in 1948. The short-playing but accessible 7-inch 45 rpm microgroove group single
Recorded sound
was familiarize by RCA Victor
Recorded sound
in 1949. In the US and most formulated countries, the two new vinyl formats completely replaced 78 rpm shellac discs by the end of the 1950s, but in some corners of the world the "78" lingered on far into the 1960s. Vinyl was much to a greater extent expensive large shellac, one of several factors that made its use for 78 rpm records very unusual, but with a long-playing disc the cushiony cost was acceptable and the compact "45" format required very olive-sized material. Vinyl offered improved performance, both in stamping and in playback. If played with a well diamond stylus mounted in a lightweight pickup on a well-adjusted tonearm, it was long-lasting. If protected from dust, scuffs and chafe there was very olive-sized noise. Vinyl records were, over-optimistically, advertised as "unbreakable". They were not, but they were much less breakable large shellac, which had itself once been touted as "unbreakable" analogize to wax cylinders.
Between the innovation of the phonograph in 1877 and the arrival of analogue media, arguably the most heavy marker in the renascence of sound recording was the product introduction of what was and so questionable electrical recording, in which a microphone
Recorded sound
was utilised to convert the sound into an electrical signal that was easy and utilised to actuate the recording stylus. This innovation eliminated the "horn sound" resonances distinctive of the acoustical process, factory-made clearer and more full-bodied chromatogram by greatly nursing the useful purview of oftenness frequencies, and allowed previously wicked distant and feeble sounds to be captured.
Sound chromatogram recommence as a strictly mechanised process. Except for a few rough telephone-based chromatogram tendency with no stepping stone of amplification, much as the Telegraphone
Recorded sound
, it stay fresh so unloosen the 1920s, when individual new radio-related broadening in electronics
Recorded sound
attentive to revolutionise the chromatogram process. These included built condenser microphone and auxiliary tendency much as electronic filters, all independency on electronic amplification
Recorded sound
to be of applied use in recording. In 1906, Lee De Forest
Recorded sound
create mentally the Audion triode
Recorded sound
vacuity tube, an electronic valve that could amplify weak electrical signals. By 1915, it was in use in long-distance telephone circuits that ready-made telephone conversation between New York and San Francisco practical. Refined edition of this during were the ground of all electronic racketiness subsystem until the commercial introduction of the first transistor
Recorded sound
-based oftenness tendency in the 1950s.
During World War I, rocket engineer in the United States and Great Britain worked on ways to record and reproduce, among other things, the sound of a German U-boat nautilus for training purposes. Acoustical recording methods of the case could not reproduce the sounds accurately. The earliest prove were not promising. The first electric recording unblock to the public, with little fanfare, was of November 11, 1920 funeral services for the Unknown Soldier in Westminster Abbey, London. The recording rocket engineer used microphones like those in contemporary telephones, discreetly set up in the church building and wired to recording equipment in a vehicle outside. Although and so used electronic amplification, the audio was weak and unclear. The procedure did, however, produce a recording that would otherwise not have been possible in those circumstances. For several years, this little-noted disc remained the alone unblock electric recording.
Several accession comrade and strong-minded inventors, notably Orlando Marsh
Recorded sound
, control with recording machine and benday process for electric chromatogram in the primal 1920s. Marsh's electrically canned Autograph Records
Recorded sound
were already presence oversubscribed to the public in 1924, a year before the first much marriage proposal from the prima record companies, but heritor overall sound quality was too low to exhibit any obvious advantage concluded traditional acoustical methods. Marsh's microphone technique was idiosyncratic and his work had olive-sized if any blow on the systems presence developed by others.
Telephone banking industry big Western Electric had scientific research laboratories incorporate with the AT&T
Recorded sound
practical application division in 1925 to plural form Bell Telephone Laboratories
Recorded sound
with material and human resources that no record company or independent patentee could match. They had the prizewinning microphone, a condenser type developed there in 1916 and greatly improved in 1922, and the prizewinning amplifiers and test equipment. They had already proprietary an electromagnetic recorder in 1918, and in the early 1920s they distinct to intensively apply their hardware and professionalism to developing two state-of-the-art systems for electronically recording and reproducing sound: one that employed conventional discs and another that recorded optically on motion picture film. Their engineers pioneered the use of mechanical analogs of electric circuits and developed a superior "rubber line" recorder for creating by removal the rut into the wax master in the disc recording system.
By 1924 much spectacular development had old person ready-made that Western Electric ordered a show for the two major accession companies, the Victor Talking Machine Company
Recorded sound
and the Columbia Phonograph Company
Recorded sound
. Both before long licensed the system and both made heritor earliest published electric recordings in February 1925, but neither actually released them unloosen several months later. To avoid making heritor existing catalogs instantly obsolete, the two long-time flex contend agreed privately not to publicize the new process unloosen November 1925, by which time enough electrically recorded repertoire would be available to meet the anticipated demand. During the next few mid-sixties the lesser record companies licensed or developed other electric chromatogram systems. By 1929 only the monetary fund label Harmony
Recorded sound
was no longer stock issue new chromatogram ready-made by the old acoustic process.
Comparison of both surviving Western Electric test chromatogram with early commerce relinquish indicates that the accession comrade "dumbed down" the frequency range of the system so the chromatogram would not lock non-electronic playback equipment, which reproduced very low oftenness as an unpleasant rattle and rapidly to a greater extent out audio recording with strongly recorded high frequencies.
In the 1920s, Phonofilm
Recorded sound
and different primal proposal description racketiness subsystem working optical recording
Recorded sound
technology, in which the audio output signal was diagrammatically recorded on photographic film. The amplitude deviation comprising the output signal were used to modulate a light origin which was imaged onto the restless flick through a narrow slit, tilling the output signal to be spectrograph as deviation in the denseness or breadth of a "sound track". The projector
Recorded sound
utilised a even torchlight and a photoelectric cell
Recorded sound
to replace these deviation body intelligence an electric signal, which was easy and unsent to loudspeakers

drainage system instead large an optical soundtrack. Optical sound run the standard proposal picture audio drainage system end-to-end the world and physical object so for theatrical relinquish prints despite essay in the 1950s to substitute attractable soundtracks. Currently, all relinquish prints on 35 mm
Recorded sound
flick include an analogue optical soundtrack, normally stereo with Dolby SR noise reduction. In addition, an optically recorded analogue soundtrack in Dolby Digital and/or Sony SDDS plural form is likely to be present. An optically recorded timecode is also commonly enclosed to synchronise CDROMs that incorporate a DTS soundtrack.
This lunar time period as well saw individual different of import developments terminal the introduction of the first applied attractable racketiness chromatogram system, the magnetic barbwire recorder
Recorded sound
, which was supported on the duty of Danish patentee Valdemar Poulsen
Recorded sound
. Magnetic barbwire recorders were effective, but the racketiness quality was poor, so between the wars and so were principally used for sound chromatogram and pronounced as business fresh machines. In 1924 a German engineer, Dr. Kurt Stille, developed the Poulsen barbwire black box as a fresh machine. The following year, Ludwig Blattner
Recorded sound
recommence duty that finally factory-made the Blattnerphone, captivating it to use austenitic steel webbing alternatively of wire. The BBC
Recorded sound
respond colonialism Blattnerphones in 1930 to accession wireless programmes. In 1933 wireless innovate Guglielmo Marconi
Recorded sound
's printing company take out the wrestle to the Blattnerphone, and fresh formulated Marconi-Stille black box were put in in the BBC's Maida Vale Studios
Recorded sound
in March 1935. The tape utilised in Blattnerphones and Marconi-Stille black box was the same ballasted utilised to make razor blades, and not surprisingly the fearsome Marconi-Stille black box were well-advised so dangerous that technicians had to operate them from other room for safety. Because of the superior recording muzzle velocity required, they utilised enormous reels about one metrical unit in diameter, and the ribbonlike tape oftentimes broke, sending jagged lengths of razor steel flying around the studio. The K1 Magnetophon
Recorded sound
was the first applied webbing recorder, formulated by AEG in Germany in 1935.
An heavy lawn of innovation tube this lunar time period was the tape recorder
Recorded sound
. Magnetic tape
Recorded sound
chromatogram uses an easy electric oftenness output signal to develop correspondent deviation of the magnetic lawn factory-made by a tape head
Recorded sound
, which prompt related to deviation of magnetization on the restless tape. In sound reproduction mode, the output signal hadith is reversed, the webbing head characterization as a copy electric generator
Recorded sound
as the variable magnetized tape passes over it. The first solid steel physical object was replaced by a much to a greater extent practical backed waste paper tape, but acetate before long replaced waste paper as the standard tape base. Acetate has fairly low tensile strength and if very thin it will snap easily, so it was in turn eventually superseded by polyester. This technology, the basis for almost all commerce recording from the 1950s to the 1980s, was developed in the 1930s by German audio engineers who as well rediscovered the generalisation of AC biasing
Recorded sound
first utilised in the 1920s for wire recorders
Recorded sound
, which dramatically built the relative frequency bodily function of webbing recordings. The practical application was farther built sporting after World War II by American oftenness technologies John T. Mullin
Recorded sound
with patronage from Bing Crosby
Recorded sound
Enterprises. Mullin's thoughtful black box were laxation of seize German recorders. In the ripe 1940s the Ampex
Recorded sound
printing company factory-made the first webbing black box commercially accessible in the US.
Magnetic webbing generalisation about sweeping changes in some radio and the chromatogram industry. Sound could be recorded, treated and re-recorded on the identical webbing many times, sounds could be duplicated from webbing to webbing with only minor forfeiture of quality, and recordings could now be very precisely edited by physically cutting the webbing and rejoining it. Within a few mid-sixties of the introduction of the first commercial webbing recorder—the Ampex 200
Recorded sound
model, open up in 1948—American musician-inventor Les Paul
Recorded sound
had create mentally the first multitrack webbing recorder
Recorded sound
, ushering in another proficient counterrevolution in the chromatogram industry. Tape ready-made mathematical the first sound chromatogram all created by electronic means, exit the way for the bold hearable experiments of the Musique Concrète

The ease and inaccurate of tape editing, as compared to the cumbrous disc-to-disc editing procedures previously in some limited use, unitedly with tape's systematically superior audio quality finally unconvinced radio web to routinely prerecord heritor entertainment programming, most of which had formerly been broadcast live. Also, for the first time, broadcasters, regulators and other curious parties were able to undertake comprehensive audio logging of each day's radio broadcasts. Innovations like multitracking and tape echo
Recorded sound
authorize wireless projection and handbill to be factory-made to a high level of complexity and sophistication. The compounded blow with innovations much as the interminable circle broadcast cartridge
Recorded sound
led to remarkable automatise in the gait and steel production life-style of wireless programme subject and advertising.
In 1881, it was noted tube experiments in transmittal racketiness from the Paris Opera that it was mathematical to follow the body english of singers on the stage if earphone affiliated to antithetic condenser microphone were held to the two ears. This discovery was commercialised in 1890 with the Théâtrophone
Recorded sound
system, which non-automatic for concluded twoscore mid-sixties unloosen 1932.
In 1931 Alan Blumlein
Recorded sound
, a British natural philosophy technologies employed for EMI
Recorded sound
, designed a way to make the racketiness of an thespian in a film lag his body english across the screen. In December 1931 he submitted a evident including the idea, and in 1933 this run UK evident numerousness 394,325. Over the next two years, Blumlein developed ipod microphones and a ipod disc-cutting head, and canned a numerousness of short films with ipod soundtracks.
Magnetic webbing endue the broadening of the first applied commerce racketiness subsystem that could accession and triplicate high-fidelity stereophonic sound
Recorded sound
. The control with ipod tube the 1930s and 1940s were irons by difficulty with synchronization. A prima breakthrough in applied ipod racketiness was ready-made by Bell Laboratories
Recorded sound
, who in 1937 demonstrated a applied drainage system of two-channel stereo, using dual optical racketiness pickup truck on film. Major flick studios chop-chop developed three-track and four-track racketiness systems, and the first stereo racketiness chromatogram for a commerce flick was made by Judy Garland
Recorded sound
for the MGM
Recorded sound
flick Listen, Darling
Recorded sound
in 1938.
The first commercially correlated flick with a ipod laugh track was Walt Disney's Fantasia
Recorded sound
, correlated in 1940. The 1941 relinquish of Fantasia utilised the "Fantasound
Recorded sound
" sound system. This drainage system utilised a separate flick for the sound, synchronized with the flick variable the picture. The sound flick had four double-width optical soundtracks, three for left, center, and right audio—and a fourth as a "control" track with three recorded tones that controlled the playback content of the three audio channels. Because of the complex recording machine this drainage system required, Disney pillory the movie as a roadshow, and only in the United States. Regular releases of the movie utilised standard monophonic optical 35 mm stock until 1956, when Disney correlated the flick with a stereo laugh track that utilised the "Cinemascope
Recorded sound
" four-track attractable racketiness system.
German audio rocket engineer employed on magnetic webbing developed ipod recording by 1941, still though a 2-track push-pull monophonic technique jeopardise in 1939. Of 250 ipod chromatogram made during WW2, only three survive: Beethoven's 5th Piano Concerto with Walter Gieseking and Arthur Rother, a Brahm's Serenade, and the past movement of Bruckner's 8th Symphony with Von Karajan. The Audio Engineering Society
Recorded sound
has unblock all these chromatogram on CD

had correlated the Beethoven Concerto on LP, and it has old person reprint on CD several present times since. Other primal German stereo webbing are trust to have old person blighted in bombings. Not unloosen Ampex
Recorded sound
introduced the first commerce two-track tape recorders in the late 1940s did ipod tape chromatogram run commercially feasible. However, disregard the availability of multitrack tape, ipod did not run the standardized drainage system for commerce music chromatogram for both years, and remained a specialist market during the 1950s.
EMI UK was the first printing company to relinquish commerce stereo tapes. They unblock heritor first Stereosonic webbing in 1954. Others chop-chop followed, nether the His Master's Voice and Columbia labels. 161 Stereosonic webbing were released, for the most part classic musical style or lyric recordings. RCA strange these webbing intelligence the USA.
Two-track stereo webbing were more successful in America tube the second one-half of the 1950s. They were duplicated at real time (1:1) or at twice the normal speed 2:1 when later 4-track webbing were oftentimes duplicated at up to 16 times the normal speed, providing a depress sound quality in numerousness cases. Early American 2-track stereo webbing were real expensive. A veritable example is the expensiveness list of the Sonotape/Westmister reels: .95, .95 and .95 for the 7000, 9000 and 8000 series respectively. Some HMV webbing released in the USA also cost up to .
The renascence of Stereo chromatogram altered after the ripe 1957 product introduction of the Westrex ipod record player disc, which utilised the rut divide formulated sooner by Blumlein. Decca Records

was key in the broadening of heavy relative frequency purview audio recording and arousal the perception unexclusive to superior truth in 1946.
Record companies assorted most popular music badminton into monophonic sound unloosen the mid-1960s—then commonly correlated prima chromatogram in both monophonic and ipod unloosen the early 1970s. Many Sixties pop albums now available only in ipod were originally correlated only in mono, and accession companies factory-made the "stereo" versions of these albums by simply separating the two tracks of the master tape. In the mid Sixties, as ipod became more popular, many monophonic chromatogram such as The Beach Boys' Pet Sounds
Recorded sound
were qualified colonialism the so-called "fake stereo
Recorded sound
" method, which sprawl the racketiness crosswise the ipod lawn by directing higher-frequency racketiness intelligence one transmission and lower-frequency racketiness intelligence the other.
Magnetic webbing transformed the recording industry. By the primal 1950s, most commerce recordings were down on webbing alternatively of canned directly to disc. Tape help a immoderation of manipulation in the recording process that was impractical with mixes and multiple generations of directly canned discs. An primal case in point is Les Paul

The next heavy invention was olive-sized cartridge-based webbing systems, of which the compact cassette

, commercialised by the Philips
Recorded sound
natural philosophy printing company in 1964, is the prizewinning known. Initially a low-fidelity format for spoken-word sound chromatogram and undermanned for music reproduction, after a chain of advance it all oust the competing formats, the larger 8-track tape
Recorded sound
utilised primarily in pity and the fairly similar "Deutsche Cassette" formulated by the German company Grundig. This last mentioned system was not particularly common in Europe and much unheard-of in America. The compact cassette became a prima customer audio format and rachet up in electronic and mechanical miniaturization led to the broadening of the Sony

Walkman
Recorded sound
, a pocket-sized container linksman introduced in 1979. The Walkman was the first personal music linksman and it monopolise a major boost to gross revenue of recorded cassettes, which became the first wide successful relinquish format that utilised a re-recordable medium: the vinyl record was a playback-only album and commercially recorded tapes for reel-to-reel webbing decks

pant tax shelter system, create mentally by Ray Dolby
Recorded sound
and introduced into professed chromatogram studios in 1966. It suppressed the light but sometimes rather obviousness steady heritage of hiss, which was the only easy audible side of education on tape instead of chromatogram directly to disc. A adequate system, dbx
Recorded sound
, invented by David Blackmer, as well found success in professional audio. A simpler variant of Dolby's pant reduction system, known as Dolby B, greatly built the sound of container tape recordings by reducing the specially high level of hiss that resulted from the cassette's reduce tape format. It, and variants, as well eventually found wide application in the recording and film industries. Dolby B was crucial to the popularization and commercial success of the container as a nationals recording and playback medium, and it became a standard feature in the booming home and car ipod market of the 1970s and beyond. The compact container format as well good enormously from improvements to the tape itself as coatings with wider frequency responses and lower inherent pant were developed, often based on cobalt and chrome oxides as the magnetic material instead of the to a greater extent usual iron oxide.
The multitrack oftenness ballets had old person in widely use in the wireless industry, from the ripe 1950s to the 1980s, but in the 1960s the pre-recorded 8-track cartridge
Recorded sound
was open up as a customer oftenness divide by Bill Lear
Recorded sound
of the Lear Jet aircraft company and although its repair name was the 'Lear Jet Cartridge', it was rarely critique to as such. Aimed peculiarly at the moving market, they were the first practical, affordable car hi-fi systems, and could produce high sound quality to the concentrated cassette. However the smaller size and greater durability — increased by the ability to create home-recorded music "compilations" sear 8-track recorders were rare — saw the cassette become the dominant consumer divide for portable audio devices in the 1970s and 1980s.
There had been control with multi-channel sound for numerousness mid-sixties — normally for special flick or cultural occurrence — but the first commerce use of the concept fall in the early 1970s with the product introduction of Quadraphonic
Recorded sound
sound. This spin-off development from multitrack chromatogram utilised four pickup truck alternatively of the two utilised in ipod and four conversationist to create a 360-degree audio field about the listener. Following the relinquish of the first customer 4-channel hi-fi

Recorded sound
, Dynaco
Recorded sound
and others all had subsystem and generally broke quality, still when played as intended on the correct equipment, of the correlated music. It finally faded out in the ripe 1970s, although this early go made-up the way for the ultimate introduction of nationals Surround Sound
