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 .
153-486: The first phonograph cylinders were manufactured in 1888, followed by Edison's foundation of the Edison Phonograph Company in the same year. The recorded wax cylinders, later replaced by Blue Amberol cylinders, and vertical-cut Diamond Discs, were manufactured by Edison's National Phonograph Company from 1896 on, reorganized as Thomas A. Edison, Inc. in 1911. Until 1910 the recordings did not carry
306-498: A telephone hybrid for putting telephone calls on the air, a POTS codec for receiving remote broadcasts , a dead air alarm for detecting unexpected silence , and a broadcast delay for dropping anything from coughs to profanity . In the U.S., stations licensed by the Federal Communications Commission (FCC) also must have an Emergency Alert System decoder (typically in the studio), and in
459-410: A turntable , is a device for the mechanical and analogue reproduction of sound . The sound vibration waveforms are recorded as corresponding physical deviations of a helical or spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a record . To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and
612-419: A "cue lever", a device that mechanically lowers the tonearm on to the record. It enables the user to locate an individual track more easily, to pause a record, and to avoid the risk of scratching the record, which may require practice to avoid when lowering the tonearm manually. Early developments in linear turntables were from Rek-O-Kut (portable lathe/phonograph) and Ortho-Sonic in the 1950s, and Acoustical in
765-614: A 12-inch (300 mm) disc, but problems occurred (notably with broken groove walls and overall low volume, often only 40% of that of the regular discs), and the disc failed. In August 1927, discs began to be electrically recorded, making Edison the last major label to adopt electrical recording (over two years after Victor, Columbia, and Brunswick had converted from acoustical recording). Concurrently, Edison tried to freshen its catalogues by recording popular dance bands such as those of B. A. Rolfe and Harry Reser (whose "Six Jumping Jacks" group appeared on Edison as "Earl Oliver's Jazz Babies"),
918-684: A 3000+ playback quota for the Blue Amberol. In that same year, the Edison Disc Record came out. In 1910, artists' names began to be added to the records; previously, Edison's policy was to promote his cylinders (and up until 1915, discs) based on the recognition of composers and the works recorded thereon in lieu of the performers themselves. Thomas A. Edison, Inc. , successor to the National Phonograph Company, continued selling cylinders until they went out of
1071-474: A Graphophone and my mother was a phonograph." Most of the disc machines designed at the Volta Lab had their disc mounted on vertical turntables. The explanation is that in the early experiments, the turntable, with disc, was mounted on the shop lathe, along with the recording and reproducing heads. Later, when the complete models were built, most of them featured vertical turntables. One interesting exception
1224-484: A definite method for accomplishing the reproduction. On April 30, 1877, he deposited a sealed envelope containing a summary of his ideas with the French Academy of Sciences , a standard procedure used by scientists and inventors to establish priority of conception of unpublished ideas in the event of any later dispute. An account of his invention was published on October 10, 1877, by which date Cros had devised
1377-400: A device that could replicate the function of the human ear. Scott coated a plate of glass with a thin layer of lampblack . He then took an acoustic trumpet, and at its tapered end affixed a thin membrane that served as the analog to the eardrum . At the center of that membrane, he attached a rigid boar's bristle approximately a centimetre long, placed so that it just grazed the lampblack. As
1530-541: A different machine that played nonrecordable discs (although Edison's original Phonograph patent included the use of discs. ) In Australian English , "record player" was the term; "turntable" was a more technical term; "gramophone" was restricted to the old mechanical (i.e., wind-up) players; and "phonograph" was used as in British English . The "phonograph" was first demonstrated in Australia on 14 June 1878 to
1683-401: A different machine, which records the combined signals (called printing ) to a 1 ⁄ 2 -inch two-track stereo tape, called a master . Before digital recording, the total number of available tracks onto which one could record was measured in multiples of 24, based on the number of 24-track tape machines being used. Most recording studios now use digital recording equipment, which limits

An alternative approach is to take a high-resolution photograph or scan of each side of the record and interpret the image of the grooves using computer software . An amateur attempt using a flatbed scanner lacked satisfactory fidelity. A professional system employed by the Library of Congress produces excellent quality. Recording studio A recording studio
1989-750: A home studio is challenging because they are usually the loudest instruments. Acoustic drums require sound isolation in this scenario, unlike electronic or sampled drums. Getting an authentic electric guitar amp sound including power-tube distortion requires a power attenuator or an isolation cabinet , or booth. A convenient compromise is amplifier modeling , whether a modeling amp, preamp/processor, or software-based guitar amp simulator. Sometimes, musicians replace loud, inconvenient instruments such as drums, with keyboards, which today often provide somewhat realistic sampling . The capability of digital recording introduced by ADAT and its comparatively low cost, originally introduced at $ 3995, were largely responsible for
2142-660: A human voice was conducted on April 9, 1860, when Scott recorded someone singing the song " Au Clair de la Lune " ("By the Light of the Moon") on the device. However, the device was not designed to play back sounds, as Scott intended for people to read back the tracings, which he called phonautograms. This was not the first time someone had used a device to create direct tracings of the vibrations of sound-producing objects, as tuning forks had been used in this way by English physicist Thomas Young in 1807. By late 1857, with support from
2295-413: A large role in the recording process. With software, a powerful, good quality computer with a fast processor can replace the mixing consoles , multitrack recording equipment, synthesizers, samplers and effects unit (reverb, echo, compression, etc.) that a recording studio required in the 1980s and 1990s. A computer thus outfitted is called a digital audio workstation , or DAW. While Apple Macintosh
2448-444: A lesser amount of diffused reflections from walls to make a good-sounding room. A drummer, vocalist, or guitar speaker cabinet, along with microphones, is acoustically isolated in the isolation booth. A typical professional recording studio today has a control room , a large live room , and one or more small isolation booths . All rooms are soundproofed by varying methods, including but not limited to, double-layer 5/8" sheetrock with
2601-550: A longer playing time (up to five minutes) than laterals and could only be played to their full advantage on Edison Diamond Disc Phonographs. This combination produced audio fidelity superior to any other home record playing system of the time. However, Edison Discs and phonographs were more expensive than their competitors'. This, together with the incompatibility of the Edison system with other discs and machines, had an adverse effect on Edison's market share. Nonetheless, Edison Discs for
2754-709: A meeting of the Royal Society of Victoria by the Society's Honorary Secretary, Alex Sutherland who published "The Sounds of the Consonants, as Indicated by the Phonograph" in the Society's journal in November that year. On 8 August 1878 the phonograph was publicly demonstrated at the Society's annual conversazione , along with a range of other new inventions, including the microphone . The phonautograph
2907-517: A mixture of sodium carbonate, sodium hydroxide, and distilled water) made better records, and the wax could be manufactured in a shorter period of time. Using hydrated alumina resulted in more desirable blanks, with fewer defects and shorter production time. The Columbia Phonograph Company used Edison recording blanks until 1894. The North American Phonograph Company was dissolved in the fall of 1894, and Edison quit supplying blanks to Columbia, who had purchased 70,000 blanks from 1889 to 1894. Columbia
3060-522: A more direct procedure: the recording stylus could scribe its tracing through a thin coating of acid-resistant material on a metal surface and the surface could then be etched in an acid bath, producing the desired groove without the complication of an intermediate photographic procedure. The author of this article called the device a phonographe , but Cros himself favored the word paleophone , sometimes rendered in French as voix du passé ('voice of
3213-508: A regular stage or film set. In the era of acoustical recordings (prior to the introduction of microphones, electrical recording and amplification), the earliest recording studios were very basic facilities, being essentially soundproof rooms that isolated the performers from outside noise. During this era it was not uncommon for recordings to be made in any available location, such as a local ballroom, using portable acoustic recording equipment. In this period, master recordings were made by cutting
SECTION 20
#17327720503173366-399: A role in the development of the gramophone , whose inventor, Emile Berliner, worked with the phonautograph in the course of developing his own device. Charles Cros , a French poet and amateur scientist, is the first person known to have made the conceptual leap from recording sound as a traced line to the theoretical possibility of reproducing the sound from the tracing and then to devising
3519-410: A rotating cylinder (later disc) made from wax. Performers were typically grouped around a large acoustic horn (an enlarged version of the familiar gramophone horn). The acoustic energy from the voices or instruments was channeled through the horn to a diaphragm to a mechanical cutting lathe , which inscribed the signal as a modulated groove directly onto the surface of the master. Electrical recording
3672-446: A saponifying agent. It was found these records were much more durable. Problems arose, however, since there was no tempering agent and hot weather caused these records to decompose. Two problems contributed to this, stearic quality varied from different makers; Aylsworth purchased some from Proctor & Gamble and found it contained too much oleic acid. Stearic acid without a tempering agent takes on moisture, and after many experiments, it
3825-497: A selection of instruments in their live room, typically instruments, amplifiers and speaker cabinets that are large, heavy, and difficult to transport (e.g., a Hammond organ ) or infeasible (as in the case of a grand piano ) to hire for a single recording session. Having musical instruments and equipment in the studio creates additional costs for a studio, as pianos have to be tuned and instruments and associated equipment needs to be maintained. General-purpose computers rapidly assumed
3978-402: A signal from one or more of the microphones in the studio could be routed to the loudspeaker in the echo chamber; the sound from the speaker reverberated through the chamber and the enhanced signal was picked up by the microphone at the other end. This echo-enhanced signal, which was often used to sweeten the sound of vocals, could then be blended in with the primary signal from the microphone in
4131-437: A similar machine. On the early phonograph's reproductive capabilities he wrote in retrospect: "It sounded to my ear like someone singing about half a mile away, or talking at the other end of a big hall; but the effect was rather pleasant, save for a peculiar nasal quality wholly due to the mechanism, although there was little of the scratching that later was a prominent feature of the flat disc. Recording for that primitive machine
4284-414: A single take. In the 1970s the large recording companies began to adopt multi-track recording and the emphasis shifted to isolation and sound-proofing, with treatments like echo and reverberation added separately during the mixing process, rather than being blended in during the recording. Generally, after an audio mix is set up on a 24-track tape machine, the tracks are played back together, mixed and sent to
4437-402: A slightly earlier one that is believed to preserve the voice of U.S. President Rutherford B. Hayes , but as of May 2014 they have not yet been scanned. These antique tinfoil recordings, which have typically been stored folded, are too fragile to be played back with a stylus without seriously damaging them. Edison's 1877 tinfoil recording of Mary Had a Little Lamb , not preserved, has been called
4590-422: A small, simple machine about which few preliminary remarks were offered. The visitor without any ceremony whatever turned the crank, and to the astonishment of all present the machine said: 'Good morning. How do you do? How do you like the phonograph?' The machine thus spoke for itself, and made known the fact that it was the phonograph..." The music critic Herman Klein attended an early demonstration (1881–82) of
4743-480: A stylus with a small diamond or sapphire tip that runs in the record groove. The stylus eventually becomes worn by contact with the groove, and it is usually replaceable. Styli are classified as spherical or elliptical, although the tip is actually shaped as a half-sphere or a half- ellipsoid . Spherical styli are generally more robust than other types, but do not follow the groove as accurately, giving diminished high frequency response. Elliptical styli usually track

4896-415: A table then put in lukewarm water. The water caused the records to shrink in diameter so that they could be removed. The records were then trimmed, dried and cleaned, then later put on warm mandrels for 2 hours where they shrank evenly. Jonas Aylsworth developed this formula. In 1908, Edison introduced Amberol Records which had a playing time of just over 4 minutes. The process of making the finished record
5049-622: A time became the third best selling brand in the United States, behind Victor and Columbia Records . With World War I various materials used in Edison Discs came in short supply, and many discs pressed during the war were made hastily and with inferior materials, notably a reformulated phenolic finishing varnish that was introduced when European chemical supplies were cut off. This resulted in problems with surface noise even on new records, and Edison's market share shrank. Prior to
5202-408: A vibrant acoustic signature as the natural reverb enhanced the sound of the recording. In this period large, acoustically live halls were favored, rather than the acoustically dead booths and studio rooms that became common after the 1960s. Because of the limits of the recording technology, which did not allow for multitrack recording techniques, studios of the mid-20th century were designed around
5355-428: Is a key goal, the musicians, singers, audio engineers and record producers still need to be able to see each other, to see cue gestures and conducting by a bandleader. As such, the live room, isolation booths, vocal booths and control room typically have windows. Amplified instruments, like electric guitars and digital keyboards, may be connected directly to the recording console using DI units and performance recorded in
5508-473: Is a soft oily wax and would not hold up over many plays. They could be a number of formulas tested by Jonas Aylsworth, Thomas Edison 's chemist. Most of the surviving 1888 recordings would be formulated from a combination of ceresin wax, carnauba wax, stearic acid , and beeswax . A record of this kind has a cigar-like smell and is physically very soft when first molded. In a year's time, the record would harden quite considerably. To play these first cylinders,
5661-613: Is a specialized facility for recording and mixing of instrumental or vocal musical performances, spoken words, and other sounds. They range in size from a small in-home project studio large enough to record a single singer-guitarist, to a large building with space for a full orchestra of 100 or more musicians. Ideally, both the recording and monitoring (listening and mixing) spaces are specially designed by an acoustician or audio engineer to achieve optimum acoustic properties (acoustic isolation or diffusion or absorption of reflected sound reverberation that could otherwise interfere with
5814-409: Is especially important for playback of quadraphonic recordings. A few specialist laser turntables read the groove optically using a laser pickup. Since there is no physical contact with the record, no wear is incurred. However, this "no wear" advantage is debatable, since vinyl records have been tested to withstand even 1200 plays with no significant audio degradation, provided that it is played with
5967-409: Is essential to preserving the ability to fine-tune lines up to the last minute. Sometimes, if the rapport between the lead actors is strong enough and the animation studio can afford it, the producers may use a recording studio configured with multiple isolation booths in which the actors can see each another and the director. This enables the actors to react to one another in real time as if they were on
6120-588: Is often identified as the oldest surviving playable sound recording, although the evidence advanced for its early date is controversial. Wax phonograph cylinder recordings of Handel 's choral music made on June 29, 1888, at The Crystal Palace in London were thought to be the oldest-known surviving musical recordings, until the recent playback by a group of American historians of a phonautograph recording of Au clair de la lune recorded on April 9, 1860. The 1860 phonautogram had not until then been played, as it

Later improvements through the years included modifications to the turntable and its drive system, stylus, pickup system, and the sound and equalization systems. The disc phonograph record was the dominant commercial audio distribution format throughout most of the 20th century, and phonographs became the first example of home audio that people owned and used at their residences.

At first, the only customers were entrepreneurs who installed nickel-in-the-slot phonographs in amusement arcades, saloons and other public places. At that time, a phonograph cost the equivalent of several months' wages for the average worker and was driven by an electric motor powered by hazardous, high-maintenance wet cell batteries. After more affordable spring-motor-driven phonographs designed for home use were introduced in 1895,

In early acoustic phonographs, the stylus vibrated a diaphragm that produced sound waves coupled to the open air through a flaring horn , or directly to the listener's ears through stethoscope -type earphones. The phonograph was invented in 1877 by Thomas Edison ; its use would rise the following year. Alexander Graham Bell 's Volta Laboratory made several improvements in

The molds with mandrels placed in the center were heated and dipped in a tank of the molten wax. These were removed and trimmed while still hot and put on

#17327720503177956-575: The Unique Quartet . A significant technological development at the Edison Laboratories was devising a method to mass-produce pre-recorded phonograph cylinders in molds. This was done by using very slightly tapered cylinders and molding in a material that contracted as it set. To Edison's disappointment, the commercial potential of this process was not realized for some years. Most of the regional Edison distributors were able to fill
8109-499: The model B reproducer must be used. The other later reproducers (such as C) were only designed for the harder black "wax" records. A later reproducer would shave down the grooves very fast, and the sound would be lost forever. In late 1888, metallic soaps were tried. At first, a lead stearate was used, but in the summer months, these records started to sweat and decompose. In 1889, Aylsworth developed an aluminum wax, using acetate of alumina and stearic acid with sodium hydroxide added as

In the 1890s, Emile Berliner initiated the transition from phonograph cylinders to flat discs with a spiral groove running from the periphery to near the centre, coining the term gramophone for disc record players, which
8568-461: The 1940s as record players or turntables, the movements of the stylus are transformed into an electrical signal by a transducer . This signal is then converted back into sound through an amplifier and one or more loudspeakers . The term "phonograph", meaning "sound writing", originates from the Greek words φωνή (phonē, meaning 'sound' or 'voice') and γραφή (graphē, meaning 'writing'). Similarly,
8721-577: The 1950s and 1960s, the sound of pop recordings was further defined by the introduction of proprietary sound processing devices such as equalizers and compressors, which were manufactured by specialist electronics companies. One of the best known of these was the Pultec equalizer which was used by almost all the major commercial studios of the time. With the introduction of multi-track recording , it became possible to record instruments and singers separately and at different times on different tracks on tape. In

By 1987, phonograph use had declined sharply due to the popularity of cassettes and the rise of the compact disc . However, records have undergone a revival since the late 2000s . This resurgence has much to do with vinyl records' sparing use of audio processing, resulting in a more natural sound on high-quality replay equipment, compared to many digital releases that are highly processed for portable players in high-noise environmental conditions. However, unlike "plug-and-play" digital audio, vinyl record players have user-serviceable parts, which require attention to tonearm alignment and

11322-489: The concept of grouping musicians (e.g., the rhythm section or a horn section ) and singers (e.g., a group of backup singers ), rather than separating them, and placing the performers and the microphones strategically to capture the complex acoustic and harmonic interplay that emerged during the performance. In the 2000s, modern sound stages still sometimes use this approach for large film scoring projects that use large orchestras. Because of their superb acoustics, many of
11475-480: The consideration of the physical dimensions of the room itself to make the room respond to sound in the desired way. Acoustical treatment includes and the use of absorption and diffusion materials on the surfaces inside the room. To control the amount of reverberation, rooms in a recording studio may have a reconfigurable combination of reflective and non-reflective surfaces. Soundproofing provides sonic isolation between rooms and prevents sound from entering or leaving
11628-436: The control room. This greatly enhances the communication between the producer and engineer with the player, as studio mics, headphones and talkback are unnecessary. Recording studios are carefully designed around the principles of room acoustics to create a set of spaces with the acoustical properties required for recording sound with accuracy. Architectural acoustics includes acoustical treatment and soundproofing and also
11781-426: The cylinder was rotated and slowly progressed along its axis , the airborne sound vibrated a diaphragm connected to a stylus that indented the foil into the cylinder's groove, thereby recording the vibrations as "hill-and-dale" variations of the depth of the indentation. By 1890, record manufacturers had begun using a rudimentary duplication process to mass-produce their product. While the live performers recorded
11934-551: The device to audiences for a fee. The tinfoil phonograph was not fit for any real practical use and public interest soon waned. In 1887, Edison turned his attention back to improving the phonograph and the phonograph cylinder . The following year, the Edison company debuted the Perfected Phonograph. Edison introduced wax cylinders approximately 4 + 1 ⁄ 4 inches (11 cm) long and 2 + 1 ⁄ 4 inches (5.7 cm) in external diameter, which became
12087-581: The earliest sound recordings available to the public. The phonautograms were then digitally converted by scientists at the Lawrence Berkeley National Laboratory in California, who were able to play back the recorded sounds, something Scott had never conceived of. Prior to this point, the earliest known record of a human voice was thought to be an 1877 phonograph recording by Thomas Edison . The phonautograph would play
12240-508: The earliest verified recordings by the famous that have survived to the present. Alexander Graham Bell and his two associates took Edison's tinfoil phonograph and modified it considerably to make it reproduce sound from wax instead of tinfoil. They began their work at Bell's Volta Laboratory in Washington, D. C., in 1879, and continued until they were granted basic patents in 1886 for recording in wax. Although Edison had invented
12393-485: The early 1960s. These were eclipsed by more successful implementations of the concept from the late 1960s through the early 1980s. The pickup or cartridge is a transducer that converts mechanical vibrations from a stylus into an electrical signal. The electrical signal is amplified and converted into sound by one or more loudspeakers . Crystal and ceramic pickups that use the piezoelectric effect have largely been replaced by magnetic cartridges . The pickup includes
12546-494: The employees were transferred to manufacturing radios. Edison's remaining wax masters and thousands of metal master molds, including unissued experimental recordings dating to several years before Diamond Discs were commercially introduced (many in a never-released 12-inch (300 mm) format), were purchased by Henry Ford , and became part of the collection of the Henry Ford Museum . They were recently deaccessioned by
12699-494: The fall of 1955, for the price of $ 59.95. The October 1955 issue of Radio & Television News magazine (page 41), had a full page detailed article on Philco's new consumer product. The all-transistor portable phonograph TPA-1 and TPA-2 models played only 45rpm records and used four 1.5 volt "D" batteries for their power supply. The "TPA" stands for "Transistor Phonograph Amplifier". Their circuitry used three Philco germanium PNP alloy-fused junction audio frequency transistors. After
12852-571: The first Dictaphone . After the Volta Associates gave several demonstrations in the City of Washington, businessmen from Philadelphia created the American Graphophone Company on March 28, 1887, in order to produce and sell the machines for the budding phonograph marketplace. The Volta Graphophone Company then merged with American Graphophone, which itself later evolved into Columbia Records . A coin-operated version of
13005-549: The first instance of recorded verse . On the occasion of the 50th anniversary of the phonograph, Edison recounted reciting Mary Had a Little Lamb to test his first machine. The 1927 event was filmed by an early sound-on-film newsreel camera, and an audio clip from that film's soundtrack is sometimes mistakenly presented as the original 1877 recording. Wax cylinder recordings made by 19th-century media legends such as P. T. Barnum and Shakespearean actor Edwin Booth are amongst
13158-407: The glass plate was slid horizontally in a well formed groove at a speed of one meter per second, a person would speak into the trumpet, causing the membrane to vibrate and the stylus to trace figures that were scratched into the lampblack. On March 25, 1857, Scott received the French patent #17,897/31,470 for his device, which he called a phonautograph. The earliest known surviving recorded sound of
13311-410: The groove more accurately, with increased high frequency response and less distortion. For DJ use, the relative robustness of spherical styli make them generally preferred for back-cuing and scratching. There are a number of derivations of the basic elliptical type, including the shibata or fine line stylus, which can more accurately reproduce high frequency information contained in the record groove. This
13464-424: The grooves of the cylinders were square, and the sound waves were saw-tooth-shaped and deep. The records came out scratchy and it was very time-consuming. The Gold Molded process involved taking a wax master and putting it in a vacuum chamber. The master record was put on a spinning mandrel, a pump removes the air from a glass bell jar, and two pieces of gold leaf were attached to an induction coil. Electrical current
13617-476: The hard rubber used to make the discs with a shellac compound. Berliner's early records had poor sound quality, however. Work by Eldridge R. Johnson eventually improved the sound fidelity to a point where it was as good as the cylinder. In the 1930s, vinyl (originally known as vinylite) was introduced as a record material for radio transcription discs , and for radio commercials. At that time, virtually no discs for home use were made from this material. Vinyl
13770-486: The industry of producing recorded entertainment cylinders for sale to the general public began in earnest. Blank records were an important part of the business early on. Most phonographs had or could be fitted with attachments for the users to make their own recordings. One important early use, in line with the original term for a phonograph as a "talking machine", was in business for recording dictation. Attachments were added to facilitate starting, stopping, and skipping back
13923-505: The industry standard. They had a maximum playing time of about 3 minutes at 120 RPM , but around the turn of the century the standard speed was increased to (first 144) and then 160 RPM to improve clarity and volume, reducing the maximum to about 2 minutes and 15 seconds. Several experimental wax cylinder recordings of music and speech made in 1888 still exist. The wax entertainment cylinder made its commercial debut in 1889 (a relatively well-preserved and freely available example from that year
14076-412: The inherent sound of the large recording rooms, many of the best studios incorporated specially-designed echo chambers , purpose-built rooms which were often built beneath the main studio. These were typically long, low rectangular spaces constructed from hard, sound-reflective materials like concrete, fitted with a loudspeaker at one end and one or more microphones at the other. During a recording session,
14229-611: The larger studios were converted churches. Examples include George Martin 's AIR Studios in London, Columbia Records 30th Street Studio in New York City, and Pythian Temple studio in New York. Facilities like the Columbia Records 30th Street Studio in New York and Abbey Road Studios in London were renowned for their identifiable sound—which was (and still is) easily identifiable by audio professionals—and for
14382-609: The local Edison retailers early practice of producing recordings in small numbers for regional markets, and helped concentrate the USA recording industry in the New York City – New Jersey area, already the headquarters of the nation's Tin Pan Alley printed music industry. In 1902, Edison's National Phonograph Company introduced Edison Gold Moulded Records , cylinder records of improved hard black wax, capable of being played hundreds of times before wearing out. These new records were under
14535-400: The master phonograph, up to ten tubes led to blank cylinders in other phonographs. Until this development, each record had to be custom-made. Before long, a more advanced pantograph -based process made it possible to simultaneously produce 90–150 copies of each record. However, as demand for certain records grew, popular artists still needed to re-record and re-re-record their songs. Reportedly,
14688-566: The matrixes to stamp disc can be shipped to other printing plants for a global distribution of recordings; cylinders could not be stamped until 1901–1902, when the gold moulding process was introduced by Edison. Through experimentation, in 1892 Berliner began commercial production of his disc records and "gramophones". His " phonograph record " was the first disc record to be offered to the public. They were five inches (13 cm) in diameter and recorded on one side only. Seven-inch (17.5 cm) records followed in 1895. Also in 1895 Berliner replaced
14841-492: The medium's first major African-American star George Washington Johnson was obliged to perform his " The Laughing Song " (or the separate "The Whistling Coon") up to thousands of times in a studio during his recording career. Sometimes he would sing "The Laughing Song" more than fifty times in a day, at twenty cents per rendition. (The average price of a single cylinder in the mid-1890s was about fifty cents.) Lambert 's lead cylinder recording for an experimental talking clock
14994-584: The mid-20th century often lacked isolation booths, sound baffles , and sometimes even speakers. A major reason that isolation was not used was that recordings in this period were typically made as live ensemble takes and all the performers needed to be able to see each other and the ensemble leader while playing. The recording engineers who trained in this period learned to take advantage of the complex acoustic effects that could be created through leakage between different microphones and groups of instruments, and these technicians became extremely skilled at capturing
15147-422: The mid-20th century, recordings were analog , made on 1 ⁄ 4 -inch or 1 ⁄ 2 -inch magnetic tape , or, more rarely, on 35 mm magnetic film , with multitrack recording reaching 8 tracks in the 1950s, 16 in 1968, and 32 in the 1970s. The commonest such tape is the 2-inch analog, capable of containing up to 24 individual tracks. Throughout the 1960s many pop classics were still recorded live in
15300-468: The mixture, and how to process it, but no idea as to what the ingredients actually were. It took over a year for Columbia to come up with the formula for cylinders. Columbia placed an ad in the Soap Makers' Journal for a practical man to work with metallic soaps. Adolph Melzer, a soap manufacturer from Evansville, Indiana took the job. Melzer devised a formula comparable to Edison's with the exception of
15453-580: The museum and sent to the Edison Historic Site (National Park Service) in New Jersey. Some of the Edison catalogue is in the public domain and available for download at the Library of Congress website. Phonograph A phonograph , later called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910), and since the 1940s a record player , or more recently
15606-458: The name by competing disc record manufacturers was rigorously challenged in court. However, in 1910, an English court decision ruled that the term had become generic; In American English , "phonograph", properly specific to machines made by Edison, was sometimes used in a generic sense as early as the 1890s to include cylinder-playing machines made by others. But it was then considered strictly incorrect to apply it to Emile Berliner 's Gramophone,
15759-435: The names of the artists. The company began to lag behind its rivals in the 1920s, both technically and in the popularity of its artists, and halted production of recordings in 1929. Thomas A. Edison invented the phonograph , the first device for recording and playing back sound, in 1877. After patenting the invention and benefiting from the publicity and acclaim it received, Edison and his laboratory turned their attention to
15912-402: The names of the components used by Edison were not labeled with ingredients but were instead indicated by number (i.e. 1, 2, 3) keeping the identities of these components a secret. Paraffin , ceresine , and ozokerite all look similar, making the tempering agent even more difficult to identifify by the wax mixer. Wax mixers were given instructions on how much of each numbered component to put in
16065-544: The new Blue Amberol Records , made out of a type of smooth, hard plastic similar to celluloid invented by Edison labs, were introduced for public sale. The first release was number 1501, a performance of the Rossini 's overture to his opera Semiramide , performed by the American Standard Orchestra. The plastic Blue Amberol records were much more durable than wax cylinders. The Edison lab claimed
16218-464: The next five years developing the New York City electric light and power system. Meanwhile, Bell, a scientist and experimenter at heart, was looking for new worlds to conquer after having patented the telephone . According to Sumner Tainter , it was through Gardiner Green Hubbard that Bell took up the phonograph challenge. Bell had married Hubbard's daughter Mabel in 1879 while Hubbard
16371-524: The number of available tracks only on the basis of the mixing console 's or computer hardware interface's capacity and the ability of the hardware to cope with processing demands. Analog tape machines are still used in some cases for their unique sonic characteristics. Radio studios are very similar to recording studios, particularly in the case of production studios which are not normally used on-air , such as studios where interviews are taped for later broadcast. This type of studio would normally have all of
16524-527: The past'). Cros was a poet of meager means, not in a position to pay a machinist to build a working model, and largely content to bequeath his ideas to the public domain free of charge and let others reduce them to practice, but after the earliest reports of Edison's presumably independent invention crossed the Atlantic he had his sealed letter of April 30 opened and read at the December 3, 1877 meeting of
16677-496: The phonograph in 1877, the fame bestowed on him for this invention was not due to its efficiency. Recording with his tinfoil phonograph was too difficult to be practical, as the tinfoil tore easily, and even when the stylus was properly adjusted, its reproduction of sound was distorted, and good for only a few playbacks; nevertheless Edison had discovered the idea of sound recording . However immediately after his discovery he did not improve it, allegedly because of an agreement to spend
16830-483: The platter, either underneath it or entirely outside of it, and is connected to the platter or counter-platter by a drive belt made from elastomeric material. The direct-drive turntable was invented by Shuichi Obata, an engineer at Matsushita (now Panasonic). In 1969, Matsushita released it as the Technics SP-10, the first direct-drive turntable on the market. The most influential direct-drive turntable
16983-502: The property. A Recording studio in an urban environment must be soundproofed on its outer shell to prevent noises from the surrounding streets and roads from being picked up by microphones inside. Equipment found in a recording studio commonly includes: Not all music studios are equipped with musical instruments. Some smaller studios do not have instruments, and bands and artists are expected to bring their own instruments, amplifiers, and speakers. However, major recording studios often have
17136-522: The record business in November 1929. However, from January 1915 onwards these were simply dubs of their commercial disc records intended for customers who still used cylinder phonographs purchased years before. The book, "Edison Cylinder Records, 1889-1912," by Allen Koenigsberg, APM Press, lists and dates all American Edison wax cylinders (2-4 min.); ISBN 0-937-612-07-3 . Cylinders that are mentioned from 1888 are sometimes called "yellow paraffin" cylinders, but these cylinders are not paraffin , which
17289-401: The recording for dictation and playback by stenographers. The business phonograph eventually evolved into a separate device from the home entertainment phonograph. Edison's brand of business phonograph was called The Ediphone ; see Phonograph cylinder and Dictaphone . Edison also holds the achievement of being one of the first companies to record the first African-American quartet to record:
17442-459: The rise of project studios in the 1990s. Today's project studios are built around software-based DAWs running on standard PC hardware. An isolation booth is either a partially enclosed area in the live room or a completely separate small room built adjacent to the live room that is both soundproofed to keep out external sounds and keep in the internal sounds. Like all the other recording rooms in sound industry, isolation booths designed for having
17595-444: The same equipment that any other audio recording studio would have, particularly if it is at a large station, or at a combined facility that houses a station group, but is also designed for groups of people to work collaboratively in a live-to-air situation. Broadcast studios also use many of the same principles such as sound isolation, with adaptations suited to the live on-air nature of their use. Such equipment would commonly include
17748-401: The saxophone players position their instruments so that microphones were virtually inside the mouth of the horn. The unique sonic characteristics of the major studios imparted a special character to many of the most famous popular recordings of the 1950s and 1960s, and the recording companies jealously guarded these facilities. According to sound historian David Simons, after Columbia took over
17901-508: The seams offset from layer to layer on both sides of the wall that is filled with foam, batten insulation, a double wall, which is an insulated wall built next to another insulated wall with an air gap in-between, by adding foam to the interior walls and corners, and by using two panes of thick glass with an air gap between them. The surface densities of common building materials determines the transmission loss of various frequencies through materials. Thomas A. Watson invented, but did not patent,
18054-523: The skill of their staff engineers. As the need to transfer audio material between different studios grew, there was an increasing demand for standardization in studio design across the recording industry, and Westlake Recording Studios in West Hollywood was highly influential in the 1970s in the development of standardized acoustic design. In New York City, Columbia Records had some of the most highly respected sound recording studios, including
18207-490: The small early market for recordings by mechanical duplication of a few dozen cylinders at a time. Molded cylinders did not become a significant force in the marketplace until the end of the 1890s, which was when molding was slow and was used only to create pantograph masters. Before using metal cylinders though Edison used paraffin paper. Mass-producing cylinders at the Edison recording studio in New Jersey largely ended
18360-501: The smaller independent studios were often owned by skilled electronics engineers who designed and built their own desks and other equipment. A good example of this is Gold Star Studios in Los Angeles, the site of many famous American pop recordings of the 1960s. Co-owner David S. Gold built the studio's main mixing desk and many additional pieces of equipment and he also designed the studio's unique trapezoidal echo chambers. During
18513-474: The sound and keep it from bleeding into the other microphones, allowing better independent control of each instrument channel at the mixing console . In animation, vocal performances are normally recorded in individual sessions, and the actors have to imagine (with the help of the director or a reader) they are involved in dialogue. Animated films often evolve rapidly during both development and production, so keeping vocal tracks from bleeding into each other
18666-408: The sound for analog or digital recording . The engineers and producers listen to the live music and the recorded "tracks" on high-quality monitor speakers or headphones . Often, there will be smaller rooms called isolation booths to accommodate loud instruments such as drums or electric guitar amplifiers and speakers, to keep these sounds from being audible to the microphones that are capturing
18819-401: The sound heard by the listener). Recording studios may be used to record singers, instrumental musicians (e.g., electric guitar, piano, saxophone, or ensembles such as orchestras), voice-over artists for advertisements or dialogue replacement in film, television, or animation, Foley , or to record their accompanying musical soundtracks. The typical recording studio consists of a room called
18972-445: The soundproof booth for use in demonstrating the telephone with Alexander Graham Bell in 1877. There are variations of the same concept, including a portable standalone isolation booth and a guitar speaker isolation cabinet. A gobo panel achieves the same effect to a much more moderate extent; for example, a drum kit that is too loud in the live room or on stage can have acrylic glass see-through gobo panels placed around it to deflect
19125-474: The sounds from other instruments or voices, or to provide "drier" rooms for recording vocals or quieter acoustic instruments such as an acoustic guitar or a fiddle . Major recording studios typically have a range of large, heavy, and hard-to-transport instruments and music equipment in the studio, such as a grand piano , Hammond organ , electric piano , harp , and drums . Recording studios generally consist of three or more rooms: Even though sound isolation
19278-444: The specific needs of an individual artist or are used as a non-commercial hobby. The first modern project studios came into being during the mid-1980s, with the advent of affordable multitrack recording devices, synthesizers and microphones. The phenomenon has flourished with falling prices of MIDI equipment and accessories, as well as inexpensive direct to disk recording products. Recording drums and amplified electric guitar in
19431-435: The studio and mixed into the track as the master recording was being made. Special equipment was another notable feature of the classic recording studio. The biggest studios were owned and operated by large media companies like RCA, Columbia and EMI, who typically had their own electronics research and development divisions that designed and built custom-made recording equipment and mixing consoles for their studios. Likewise,
19584-490: The stylus, which thus described a spiral, recording 150 grooves to the inch. The basic distinction between the Edison's first phonograph patent and the Bell and Tainter patent of 1886 was the method of recording. Edison's method was to indent the sound waves on a piece of tin foil, while Bell and Tainter's invention called for cutting, or "engraving", the sound waves into a wax record with a sharp recording stylus. In 1885, when
19737-541: The tempering agent (using cocinic acid, derived from coconut oil instead.) In 1901 The Gold Molded (originally spelled Moulded) process was perfected for commercial use by Thomas Edison and Jonas Aylsworth (Edison's Chemist) with input from Walter Miller, the Recording Manager of Edison Records. This discussion was gleaned from facts provided by Walter Miller, Jonas Aylsworth, Thomas Edison, Adolphe Melzer, and Charles Wurth. At first, no method of mass production
19890-405: The tension between the styli to control recording volume and tracking. The Edison team experimented with Vacuum Deposited Gold masters as early as 1888, and it has been reported that some brown wax records were molded, although this is unproven. The Edison Record, "Fisher Maiden", was an early record that was experimented with for the process. The 1888 experiments were not successful due to the fact
20043-531: The terms "gramophone" and "graphophone" have roots in the Greek words γράμμα (gramma, meaning 'letter') and φωνή (phōnē, meaning 'voice'). In British English , "gramophone" may refer to any sound-reproducing machine that utilizes disc records . These were introduced and popularized in the UK by the Gramophone Company . Initially, "gramophone" was a proprietary trademark of the company, and any use of
20196-458: The time, but they sold poorly not only because Edison's market share had declined to the point where it was no longer one of the leading companies and Edison had few distributors compared to leaders like Victor , Columbia , and Brunswick , but also because their brief existence did not allow them to establish any kind of market presence. After Edison Records closed down in October 1929, many of
20349-420: The time. Although several hundred lateral cut masters and stampers had been made by January 1929, the first "Needle Cut" discs were not released until August, and new titles were issued at a rate of only a few at a time each week for ten weeks before the company ceased record sales, thus only about 100 titles ever commercially appeared. The audio fidelity was often comparable to the best of other record companies of
20502-571: The unique acoustic properties of their studios and the musicians in performance. It was not until the 1960s, with the introduction of the high-fidelity headphones that it became common practice for performers to use these to monitor their performance during recording and listen to playbacks. The use of different kinds of microphones and their placement around the studio is a crucial part of the recording process, and particular brands of microphones are used by engineers for their specific audio characteristics. The smooth-toned ribbon microphones developed by
20655-412: The war Edison Records started a marketing campaign, hiring prominent singers and vaudeville performers to perform alongside and alternating with Edison records of their performances played on top-of-the-line "Laboratory Model" Edison Diamond Disc Phonographs. At various stages during the performances, all lights in the theater would be darkened and the audience challenged to guess if what they were hearing
20808-585: The wear and choice of stylus, the most critical component affecting turntable sound. The terminology used to describe record-playing devices is not uniform across the English-speaking world. In modern contexts, the playback device is often referred to as a "turntable", "record player", or " record changer ". Each of these terms denotes distinct items. When integrated into a DJ setup with a mixer , turntables are colloquially known as "decks". In later versions of electric phonographs, commonly known since
20961-568: The working title of "Edison Hi-Speed Extra Loud Moulded Records", running at the speed of 160 RPM instead of the usual (ca. 1898–1902) speed of 144 RPM or (ca. 1889–1897) 120 RPM. Until ca. 1898, Edison's speed was 125 RPM. In 1908, Edison introduced a new line of cylinders (called Amberol ) playing 4 rather than 2 minutes of music on the same sized record, achieved by shrinking the grooves and spacing them twice as close together. New machines were sold to play these records, as were attachments for modifying existing Edison phonographs. In November 1912,
21114-548: Was a comparatively simple matter. I had to keep my mouth about six inches away from the horn and remember not to make my voice too loud if I wanted anything approximating to a clear reproduction; that was all. When it was played over to me and I heard my own voice for the first time, one or two friends who were present said that it sounded rather like mine; others declared that they would never have recognised it. I daresay both opinions were correct." The Argus newspaper from Melbourne, Australia, reported on an 1878 demonstration at
21267-441: Was a horizontal seven inch turntable. The machine, although made in 1886, was a duplicate of one made earlier but taken to Europe by Chichester Bell . Tainter was granted U.S. patent 385,886 on July 10, 1888. The playing arm is rigid, except for a pivoted vertical motion of 90 degrees to allow removal of the record or a return to starting position. While recording or playing, the record not only rotated, but moved laterally under
21420-452: Was applied, and a magnet was spun around the outside to turn the mandrel, and the gold vaporized applying a very thin coating on the master. This master was put on a motor in a plating tank and copper was used to back the gold. The master record was melted, then taken out of the mold to reveal a negative of the grooves in the metal. The master cylinder had to have the wider feed as the grooves shrink in length through each process. The master mold
21573-461: Was available for cylinder records. Copies were made by having the artist play over and over or by hooking two machines together with rubber tubing (one with a master cylinder and the other a blank) or copying the sound mechanically. By the late 1890s, an improved mechanical duplicator, the pantograph , was developed which used mechanical linkage. One mandrel had a playback stylus and the other for recording, while weights and springs were used to adjust
21726-413: Was caused by the repetition of the convivial song of 'He's a jolly good fellow,' which sounded as if it was being sung by an old man of 80 with a cracked voice." Edison's early phonographs recorded onto a thin sheet of metal, normally tinfoil , which was temporarily wrapped around a helically grooved cylinder mounted on a correspondingly threaded rod supported by plain and threaded bearings . While
21879-442: Was common by the early 1930s, and mastering lathes were electrically powered, but master recordings still had to be cut into a disc, by now a lacquer, also known as an Acetate disc . In line with the prevailing musical trends, studios in this period were primarily designed for the live recording of symphony orchestras and other large instrumental ensembles. Engineers soon found that large, reverberant spaces like concert halls created
22032-466: Was essentially the same as the Gold Molded records, however, a harder wax compound was used. In 1912, celluloid was used in place of wax, and the name was changed to Blue Amberol, as the dye was blue. What differed from earlier process was that a steam jacketed mold with an air bladder in the center was used. Celluloid tubing was put in the mold and the end gate was closed. The rubber bladder expanded
22185-548: Was found that Ceresine was ideal. To make the wax hard, sodium carbonate was added. Even so, a few batches of records still had problems and became fogged. The fog problem arose from acetic acid left in the wax and was solved when higher temperatures were used to make sure the acetic acid was boiled out of the wax. As such, the records from 1889 to 1894 are a reddish-brown color due to the long cooking time. By 1896, Edison started using hydrated alumina in place of acetate of alumina. The use of hydrated alumina (sheet aluminum dissolved in
22338-554: Was frantic to find a solution to make cylinder blanks in-house, and the recipe for making Edison's wax was a well-kept secret. Thomas MacDonald experimented with wax alloys with poor results: the records fogged or decomposed in the summer, just like the early Edison blanks. The Columbia company had a deadline to either supply recordings, or have their contracts canceled and be sued for loss of records. Columbia resorted to hiring old Edison Phonograph Works employees, such as Mr. Storms, in order to learn their secrets. Unfortunately for Columbia,
22491-605: Was invented on March 25, 1857, by Frenchman Édouard-Léon Scott de Martinville , an editor and typographer of manuscripts at a scientific publishing house in Paris. One day while editing Professor Longet's Traité de Physiologie , he happened upon that customer's engraved illustration of the anatomy of the human ear, and conceived of "the imprudent idea of photographing the word." In 1853 or 1854 (Scott cited both years) he began working on "le problème de la parole s'écrivant elle-même" ("the problem of speech writing itself"), aiming to build
22644-523: Was live or recorded; accounts often said that much of the audience was astonished when the lights went back up to reveal only the Edison Phonograph on stage. According to a book published by the Edison company titled Composers and Artists whose Art is Re-Created by Edison's New Art (ca. 1920), the first such comparison test or "tone test" as Edison copywriters referred to them, took place at Carnegie Hall on April 28, 1916 with Marie Rappold of
22797-592: Was only a transcription of sound waves into graphic form on paper for visual study. Recently developed optical scanning and image processing techniques have given new life to early recordings by making it possible to play unusually delicate or physically unplayable media without physical contact. A recording made on a sheet of tinfoil at an 1878 demonstration of Edison's phonograph in St. Louis, Missouri, has been played back by optical scanning and digital analysis. A few other early tinfoil recordings are known to survive, including
22950-443: Was practical and their machines were durable. But it would take several more years and the renewed efforts of Edison and the further improvements of Emile Berliner and many others, before the recording industry became a major factor in home entertainment . Discs are not inherently better than cylinders at providing audio fidelity. Rather, the advantages of the format are seen in the manufacturing process: discs can be stamped, and
23103-601: Was president of the Edison Speaking Phonograph Co., and his organization, which had purchased the Edison patent, was financially troubled because people did not want to buy a machine that seldom worked well and proved difficult for the average person to operate. The sound vibrations had been indented in the wax that had been applied to the Edison phonograph. The following was the text of one of their recordings: "There are more things in heaven and earth, Horatio, than are dreamed of in your philosophy. I am
23256-669: Was the Technics SL-1200 , which, following the spread of turntablism in hip hop culture, became the most widely-used turntable in DJ culture for several decades. In some high quality equipment the arm carrying the pickup, known as a tonearm, is manufactured separately from the motor and turntable unit. Companies specialising in the manufacture of tonearms include the English company SME . More sophisticated turntables were (and still are) frequently manufactured so as to incorporate
23409-399: Was used for the popular 78-rpm V-discs issued to US soldiers during World War II . This significantly reduced breakage during transport. The first commercial vinylite record was the set of five 12" discs " Prince Igor " (Asch Records album S-800, dubbed from Soviet masters in 1945). Victor began selling some home-use vinyl 78s in late 1945; but most 78s were made of a shellac compound until
