Loop Bin Duplicator
A loop bin duplicator is a specialized audio tape machine used in the duplication of pre-recorded audio cassettes and 8-track cartridges. Digital loop bin duplicators were first introduced in the early 1990s. They had fewer moving parts than previous systems, so were more reliable to operate. Analog loop bin duplicator An analog loop bin uses a long loop of either 1/2" wide (for cassette duplication) or 1" wide (for 8-track tape duplication) loaded in a large bin located in the front of the duplicator. This loop master tape is loaded into the duplicator's bin from a traditional open-reel of tape, where the program material has been recorded to it using a studio-type multitrack tape recorder in real-time beforehand. The loop tape for cassette duplication has 4 tracks on the loop bin master tape (2 stereo tracks for Side A recorded in one direction, and the other 2 for Side B recorded in the opposite direction), and for 8-tracks has all of the 8 tracks (4 2-track stereo progr ...

Audio Tape
Audiotape is magnetic tape used for storing audio. Information stored can be in the form of either an analog or digital signal. Audiotape can be used in various tape recorders including machines for reel-to-reel audio tape recording on open reels or they can be enclosed in cases that only have one reel ( tape cartridge) or two reels (cassette tape). History The use of magnetic tape for sound recording can be traced back to 1924 when German engineer, Kurt Stille, developed a dictation machine that used steel wires called the Poulsen wire recorder. Louis Blattner, a German engineer working in Britain, licensed Stille's technology the following year and started work on a machine that would be able to record on a magnetic steel tape. The machine would later be called the Blattnerphone. The machine used steel tape that was 6 mm wide and 0.08 mm thick. It travelled at 5 feet per second and was able to record up to 20 minutes of audio. Although the tape was used by some organizations l ...

Compact Audio 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—essentially ...

8-track Tape
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound recording technology that was popular from the mid-1960s until the early 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music. The format was commonly used in cars and was most popular in the United States and Canada and, to a lesser extent, in the United Kingdom, Ireland and Japan. One advantage of the 8-track tape cartridge was that it could play continuously in an endless loop, and did not have to be ejected, turned around and reinserted to play the entire tape. After about 80 minutes of playing time, the tape would start again at the beginning. Because of the loop, there is no rewind. The only options the user has are play, fast forward, record, and program (track) change. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Inches Per Second
The inch per second is a unit of speed or velocity. It expresses the distance in inches (''in'') traveled or displaced, divided by time in seconds (''s'', or ''sec''). The equivalent SI unit is the metre per second. Abbreviations include in/s, in/sec, ips, and less frequently in s−1. Conversions 1 inch per second is equivalent to: : = 0.0254 metres per second (exactly) : = or 0.08 feet per second (exactly) : = or 0.056 miles per hour (exactly) : = 0.09144 km·h−1 (exactly) 1 metre per second ≈ 39.370079 inches per second (approximately) 1 foot per second = 12 inches per second (exactly) 1 mile per hour = 17.6 inches per second (exactly) 1 kilometre per hour ≈ 10.936133 inches per second (approximately) Uses In magnetic tape sound recording, magnetic tape speed is often quoted in inches per second (abbreviated "ips ...

Film
A film, also known as a movie or motion picture, is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, emotions, or atmosphere through the use of moving images that are generally, since the 1930s, synchronized with sound and (less commonly) other sensory stimulations. Etymology and alternative terms The name "film" originally referred to the thin layer of photochemical emulsion on the celluloid strip that used to be the actual medium for recording and displaying motion pictures. Many other terms exist for an individual motion-picture, including "picture", "picture show", "moving picture", "photoplay", and "flick". The most common term in the United States is "movie", while in Europe, "film" is preferred. Archaic terms include "animated pictures" and "animated photography". "Flick" is, in general a slang term, first recorded in 1926. It originates in the verb flicker, owing to the flickering appearance of early films ...

Arpeggio
An arpeggio () is a type of Chord (music), chord in which the Musical note, notes that compose a chord are individually sounded in a progressive rising or descending order. Arpeggios on keyboard instruments may be called rolled chords. Arpeggios may include all notes of a musical scale, scale or a partial set of notes from a scale, but must contain notes of at least three Pitch (music), pitches (two-pitch sequences are known as Trill (music), trills). Arpeggios may sound notes within a single octave or span multiple octaves, and the notes may be sustained and overlap or be heard separately. An arpeggio for the chord of C major going up two octaves would be the notes (C, E, G, C, E, G, C). In musical notation, a very rapid arpeggiated chord may be written with a wavy vertical line in front of the chord. Typically these are read as to be played from the lowest to highest note, though composers may specify a high to low sequence by adding an arrow pointing down. Arpeggios ...

Motorboating (electronics)
In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones. It is a problem encountered particularly in transmitter, radio transceivers and older vacuum tube audio systems, guitar amplifiers, public address system, PA systems and is caused by some type of unwanted feedback in the circuit. The amplifying devices in audio and radio equipment are vulnerable to a variety of feedback problems, which can cause distinctive noise in the output. The term motorboating is applied to oscillations whose frequency is below the range of hearing, from 1 to 10 hertz (unit), hertz, so the individual oscillations are heard as pulses. Sometimes the oscillations can even be seen visually as the woofer cones in speakers slowly moving in and out. Be ...

XDR (audio)
XDR (expanded dynamic range), also known as SDR (super dynamic range) is a quality-control and duplication process for the mass-production of pre-recorded audio cassettes. It is a process designed to provide higher quality audio on pre-recorded cassettes by checking the sound quality at all stages of the tape duplication process. In this way, the dynamic range of audio recorded on an XDR-duplicated cassette can be up to 13 decibels greater. History XDR (Expanded Dynamic Range) was originally developed by Capitol Records in LA in their R&D facility. Before they had released anything Capitol Records-EMI of Canada was made aware of this activity and was able to release their own version called SDR (Super Dynamic Range) ahead of the American version. Capitol Records Canada was able to do this for the following reasons: :-Back in the early 80's Capitol Records Canada functioned separately from the US counterparts. :-Capitol Records Canada involved a three person team to bring this ...

Hard Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating hard disk drive platter, platters coated with magnetic material. The platters are paired with disk read-and-write head, magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual Block (data storage), blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small disk enclosure, rectangular box. Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for History of general-purpose CPUs, general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Digital-to-analog Converter
In electronics, a digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. An analog-to-digital converter (ADC) performs the reverse function. DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals. These two applications use DACs at opposite ends of the frequency/resolution trade-off. The audio DAC is a low-frequency, high-resolution type while the video DAC is a high-frequency low- to medium-resolution type. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others. Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application. Due to the complexity ...

Buffer (computer Science)
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes within a computer, comparable to buffers in telecommunication. Buffers can be implemented in a fixed memory location in hardware or by using a virtual data buffer in software that points at a location in the physical memory. In all cases, the data stored in a data buffer is stored on a physical storage medium. The majority of buffers are implemented in software, which typically use RAM to store temporary data because of its much faster access time when compared with hard disk drives. Buffers are typically used when there is a difference between the rate at which data is received and the rate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

S-VHS
S-VHS, the common initialism for Super VHS, is an analog video cassette format introduced by JVC in 1987 as an improved version of the VHS (Video Home System) format. S-VHS improved image quality by increasing the bandwidth of the luminance (brightness) signal, allowing for a horizontal resolution of approximately 400 lines, compared to the 240 lines typical of VHS. The format used the same physical cassette shell as VHS but required higher-grade magnetic tape and compatible recording and playback equipment. S-VHS decks are backward-compatible with standard VHS tapes, allowing them to play and record in VHS format. However, S-VHS tapes generally cannot be played in VHS-only machines, due to differences in the signal encoding. Despite its technical advantages, S-VHS struggled to gain widespread consumer adoption due to the higher cost of equipment and tapes, along with the limited availability of pre-recorded content. The format found moderate success in professional, educa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
