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 ste ...

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), is used for answering telephone calls and recording callers' messages. When a telephone rings a set number of times predetermined by the call's recipient the answering machine will activate and play either a generic announcement or a customized greeting created by the recipient. Unlike voicemail, an answering machine is placed at the user's premises alongside—or incorporated within—the user's landline telephone, and unlike operator messaging, the caller does not talk to a human. As landlines become less important due to the shift to cell phone technology, and as unified communications evolve, the installed base of TADs is shrinking. History Most 20th-century answering machines used magnetic recording, which Valdemar Poulsen invent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philips
Koninklijke Philips N.V. (), simply branded Philips, is a Dutch multinational health technology company that was founded in Eindhoven in 1891. Since 1997, its world headquarters have been situated in Amsterdam, though the Benelux headquarters is still in Eindhoven. The company gained its royal honorary title in 1998. Philips was founded by Gerard Philips and his father Frederik, with their first products being light bulbs. Through the 20th century, it grew into one of the world's largest electronics conglomerates, with global market dominance in products ranging from kitchen appliances and electric shavers to light bulbs, televisions, cassettes, and compact discs (both of which were invented by Philips). At one point, it played a dominant role in the entertainment industry (through PolyGram). However, intense competition from primarily East Asian competitors throughout the 1990s and 2000s led to a period of downsizing, including the divestment of its lighting and c ...

Compact Cassette
The Compact Cassette, also commonly called a 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, the Compact Cassette was released in August 1963. Compact Cassettes come in two forms, either 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 used to refer to the Compact Cassette because of its ubiquity. From 1983 to 1991 the cassette tape was the most popular audio format for new music sales in the United States. Compact Cassettes contain two miniature spools, between which the magnetically coated, polyester-type plastic film (magnetic tape) is passed and wound—essentia ...

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 stylistic choice. The standards of sound quality (fidelity) and music production have evolved over 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"). Some subsets of lo-fi music have become popular for their perceived nostalgic and/or relaxing qualities, which originate from the imperfections that define the genre. Traditionally, lo-fi has been characterized by the inclusion of elements normally viewed as undesirable in most professional contexts, such as misplayed notes, environmental interference, or phonographic imperfections (degraded audio signals, ...

Sound Collage
In music, montage (literally "putting together") or sound collage ("gluing together") is a technique where newly branded sound objects or Musical composition, compositions, including songs, are created from collage, also known as musique concrète. This is often done through the use of sampling (music), sampling, while some sound collages are produced by gluing together sectors of different vinyl records. Like its visual cousin, sound collage works may have a completely different effect than that of the component parts, even if the original parts are recognizable or from a single source. Audio collage was a feature of the audio art of John Cage, Fluxus, postmodern music, postmodern hip-hop and postconceptual digital art. History The origin of sound collage can be traced back to the works of Heinrich Ignaz Biber, Biber's programmatic sonata ''Battalia'' (1673) and Wolfgang Amadeus Mozart, Mozart's ''Don Giovanni'' (1789), and certain passages in Gustav Mahler, Mahler symphonies as ...

Field Recording
Field recording is the production of audio recordings outside recording studios, and the term applies to recordings of both natural and human-produced sounds. It can also include the recording of electromagnetic fields or vibrations using different microphones like a passive magnetic antenna for electromagnetic recordings or contact microphones, or underwater field recordings made with hydrophones to capture the sounds and/or movements of whales, or other sealife. These recordings are often regarded as being very useful for sound designers and foley artists. Field recording of natural sounds, also called phonography (a term chosen because of the similarity of the practice 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 rec ...

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 Indeterminacy in music, indeterminacy, in which the composer introduces the elements of chance or unpredictability with regard to either the composition or its performance. Artists may 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 (music), indeterminacy techniques and seeking unknown outcomes. In France, as early as 1953, Pierre Schaeffer had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underground Music
Underground music is music with practices perceived as outside, or somehow opposed to, Popular music, mainstream popular music culture. Underground styles lack the commercial success of popular music movements, and may involve the use of avant-garde or abrasive approaches. Underground music may be perceived as expressing sincerity and creative freedom in opposition to those practices deemed formulaic or market-driven. Notions of individuality and non-conformity are also commonly deployed. The term has been applied to artists in styles such as psychedelic music, psychedelia, punk music, punk, alternative rock, electronica, industrial music, and wider strains of experimental music. Overview The term "underground music" has been applied to various artistic movements, for instance the psychedelic music movement of the mid-1960s, but the term has in more recent decades come to be defined by any musicians who tend to avoid the trappings of the mainstream commercial music industry.

Bias Current
In electronics, biasing is the setting of DC (direct current) operating conditions (current and voltage) of an electronic component that processes time-varying signals. Many electronic devices, such as diodes, transistors and vacuum tubes, whose function is processing time-varying ( AC) signals, also require a steady (DC) current or voltage at their terminals to operate correctly. This current or voltage is called ''bias''. The AC signal applied to them is superposed on this DC bias current or voltage. The operating point of a device, also known as bias point, quiescent point, or Q-point, is the DC voltage or current at a specified terminal of an active device (a transistor or vacuum tube) with no input signal applied. A bias circuit is a portion of the device's circuit that supplies this steady current or voltage. Overview In electronics, 'biasing' usually refers to a fixed DC voltage or current applied to a terminal of an electronic component such as a diode, transistor ...

Walkman
is a brand of Personal stereo, portable audio players manufactured by Sony since 1979. It was originally introduced as a portable Compact Cassette, cassette player and later expanded to include a range of portable audio products. Since 2011, the brand has referred exclusively to digital flash memory players. The Walkman became widely popular during the 1980s for its portable design and private listening experience. It influenced popular culture by promoting individualized music consumption and supporting activities such as aerobics. Its widespread use gave rise to the "Walkman effect," a term describing how portable music devices and headphones allow listeners to control their sonic environment. In 1986, "Walkman" was added to the Oxford English Dictionary, and in some markets the term became a genericized trademark for portable audio players. The Walkman also contributed to the widespread adoption of the Compact Cassette format, which surpassed vinyl record sales in 1983. Son ...
