Microcassette
The Microcassette (often written generically as microcassette) is an audio storage medium, introduced by Olympus in 1969. It has the same width of magnetic tape as the Compact Cassette but in a cassette roughly one quarter the size. By using thinner tape and half or a quarter the tape speed, microcassettes can offer comparable recording time to the compact cassette but in a smaller package. History Microcassettes have mostly been used for recording voice. In particular, they are commonly used in dictation machines and answering machines. Microcassettes have also been used in computer data storage and to record music. For the latter purpose, devices for recording in stereo were produced in 1982 and, for higher fidelity, microcassettes using Type IV ("metal", i.e. coated with pure metal particles rather than oxide) tape were sold. This was an attempt by Olympus to cash in on the burgeoning Walkman market; one model, the Olympus SR-11, had a built-in radio and offered a stere ...

Answering Machine
An answering machine, answerphone or message machine, also known as telephone messaging machine (or TAM) in the United Kingdom, UK and some Commonwealth countries, ansaphone or ansafone (from a trade name), or telephone answering device (TAD), was used for answering telephones and recording callers' messages. If a phone rings a number of times predetermined by the phone's owner, and nobody is present to answer the incoming call, the answering machine will activate and play either a generic announcement or the voice of the person being called announcing that nobody is able to come to the phone at the moment. Following the announcement is a beeping tone which prompts the caller to record a message after the tone concludes. Unlike voicemail, which can be a centralized or networked system that covers, and mostly extends, similar functions, an answering machine is set up in the user's premises alongside—or incorporated within—the user's land-line telephone. Unlike operator mes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compact Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge an ...

Dictaphone
Dictaphone was an American company founded by Alexander Graham Bell that produced dictation machines. It is now a division of Nuance Communications, based in Burlington, Massachusetts. Although the name "Dictaphone" is a trademark, it has become genericized as a means to refer to any dictation machine. History The Volta Laboratory was established by Alexander Graham Bell in Washington, D.C. in 1881. When the Laboratory's sound recording inventions were sufficiently developed with the assistance of Charles Sumner Tainter and others, Bell and his associates created the Volta Graphophone Company, which later merged with the American Graphophone Company, which itself later evolved into Columbia Records. The name "Dictaphone" was trademarked by the Columbia Graphophone Company in 1907, which soon became the leading manufacturer of such devices. This perpetuated the use of wax cylinders for voice recording, which had otherwise been eclipsed by disc-based technology. Di ...

Mini-cassette
The Mini-Cassette, often written minicassette, is a magnetic tape audio cassette format introduced by Philips in 1967. It is used primarily in dictation machines and was also employed as a data storage for the Philips P2000 home computer. As of August 2021, Phillips still produces mini-cassette players along with new mini-cassette tapes. Design Unlike the Compact Cassette, also designed by Philips, and the later Microcassette, introduced by Olympus, the Mini-Cassette does not use a capstan drive system; instead, the tape is propelled past the tape head by the reels. This is mechanically simple and allows the cassette to be made smaller and easier to use, but produces a system unsuited to any task other than voice recording, as the tape speed is not constant (averaging 2.4 cm/s) and prone to wow and flutter. However, the lack of a capstan and a pinch roller drive means that the tape is well-suited to being repeatedly shuttled forward and backward short distances as co ...

Olympus Corporation
is a Japanese manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus holds roughly a 70-percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Its global headquarters are located in Shinjuku, Tokyo, Japan. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO and the matter snowballed into a corporate corruption investigation with multiple arrests. It paid $646 million in kickback fines in 2016. Products Cameras and audio In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. The first innovative camera series from Olympus was the Pen, launched in 1959. It used a half-frame forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picocassette
Picocassette is an audio storage medium introduced by Dictaphone in collaboration with JVC in 1985. The Picocassette was introduced to compete with the Microcassette, introduced by Olympus, and the Mini-Cassette, by Philips. Size It is approximately half the size of the previous Microcassette, and was intended for highly portable dictation devices. With a tape speed of 9 millimeters per second, each cassette could hold up to 60 minutes of dictation, May 27, 1985, '' Time.com'', Retrieved 2010-04-06 30 minutes per side. The |
Philips
Koninklijke Philips N.V. (), commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, it has been mostly headquartered in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was formerly one of the largest electronics companies in the world, but is currently focused on the area of health technology, having divested its other divisions. The company was founded in 1891 by Gerard Philips and his father Frederik, with their first products being light bulbs. It currently employs around 80,000 people across 100 countries. The company gained its royal honorary title (hence the ''Koninklijke'') in 1998 and dropped the "Electronics" in its name in 2013, due to its refocusing from consumer electronics to healthcare technology. Philips is organized into three main divisions: Personal Health (formerly Philips Consumer Electronics and Philips Domestic Appliances and Personal Care), Connecte ...

Lo-fi Music
Lo-fi (also typeset as lofi or low-fi; short for low fidelity) is a music or production quality in which elements usually regarded as imperfections in the context of a recording or performance are present, sometimes as a deliberate choice. The standards of sound quality ( fidelity) and music production have evolved throughout the decades, meaning that some older examples of lo-fi may not have been originally recognized as such. Lo-fi began to be recognized as a style of popular music in the 1990s, when it became alternately referred to as DIY music (from "do it yourself"). Harmonic distortion and " analog warmth" are sometimes confused as core features of lo-fi music. Traditionally, lo-fi has been characterized by the inclusion of elements normally viewed as undesirable in professional contexts, such as misplayed notes, environmental interference, or phonographic imperfections (degraded audio signals, tape hiss, and so on). Pioneering, influential, or otherwise significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Collage
In music, montage (literally "putting together") or sound collage ("gluing together") is a technique where newly branded sound objects or compositions, including songs, are created from collage, also known as montage. This is often done through the use of sampling, while some playable sound collages were produced by gluing together sectors of different vinyl records. In any case, it may be achieved through the use of previous sound recordings or musical scores. Like its visual cousin, the collage work may have a completely different effect than that of the component parts, even if the original parts are completely recognizable or from only one source. History The origin of sound collage can be traced back to the works of Biber's programmatic sonata ''Battalia'' (1673) and Mozart's ''Don Giovanni'' (1789), and some critics have described certain passages in Mahler symphonies as collage, but the first fully developed collages occur in a few works by Charles Ives, whose piece ...

Field Recording
Field recording is the term used for an audio recording produced outside a recording studio, and the term applies to recordings of both natural and human-produced sounds. It also applies to sound recordings like electromagnetic fields or vibrations using different microphones like a passive magnetic antenna for electromagnetic recordings or contact microphones. For underwater field recordings, a field recordist uses hydrophones to capture the sounds and/or movements of whales, or other aquatic organisms. These recordings are very useful for sound designers. Field recording of natural sounds, also called phonography (a term chosen to illustrate its similarities to photography), was originally developed as a documentary adjunct to research work in the field, and foley work for film. With the introduction of high-quality, portable recording equipment, it has subsequently become an evocative artform in itself. In the 1970s, both processed and natural phonographic recordings, (p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Music
Experimental music is a general label for any music or music genre that pushes existing boundaries and genre definitions. Experimental compositional practice is defined broadly by exploratory sensibilities radically opposed to, and questioning of, institutionalized compositional, performing, and aesthetic conventions in music. Elements of experimental music include indeterminate music, in which the composer introduces the elements of chance or unpredictability with regard to either the composition or its performance. Artists may also approach a hybrid of disparate styles or incorporate unorthodox and unique elements. The practice became prominent in the mid-20th century, particularly in Europe and North America. John Cage was one of the earliest composers to use the term and one of experimental music's primary innovators, utilizing indeterminacy techniques and seeking unknown outcomes. In France, as early as 1953, Pierre Schaeffer had begun using the term ''musique expérimentale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
