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. 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 programs) r ...

Audio Tape
An audio tape recorder, also known as a tape deck, tape player or tape machine or simply a tape recorder, is a sound recording and reproduction device that records and plays back sounds usually using magnetic tape for storage. In its present-day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal. Tape-recording devices include the reel-to-reel tape deck and the cassette deck, which uses a cassette for storage. The use of magnetic tape for sound recording originated around 1930 in Germany as paper tape with oxide lacquered to it. Prior to the development of magnetic tape, magnetic wire recorders had successfully demonstrated the concept of magnetic recording, but they never offered audio quality comparable to the other recording and broadcast standards of the time. This German invention was the start of a long string of innovations that have led to present-day magnetic ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compact Audio 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 and reel ...

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 to 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 most popular in the United States, the United Kingdom, Canada, New Zealand, Australia, Mexico, Spain, France, Germany, Italy, Sweden and Japan. One advantage of the 8-track tape cartridge was that it could play continuously, and did not have to be "flipped over" to play the entire tape. It is now considered to be obsolete, although there are collectors that refurbish these tapes and players as well as some bands that issue these tapes as a novelty(Cheap Trick's "The Latest" in 2009 and Dolly Parton's "A Holly Dolly Christmas" in 2020 with a track that's only available on the 8 track) The Stereo 8 Cartridge was created in 1964 by a consorti ...

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 called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photography, photographing actual scenes with a movie camera, motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of computer-generated imagery, CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still imag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arpeggio
A broken chord is a chord broken into a sequence of notes. A broken chord may repeat some of the notes from the chord and span one or more octaves. An arpeggio () is a type of broken chord, in which the notes that compose a chord are played or sung in a rising or descending order. An arpeggio may also span more than one octave. Being an Italian noun, its plural is ''arpeggi''. The word ''arpeggio'' comes from the Italian word ''arpeggiare'', which means ''to play on a harp''. Even though the notes of an arpeggio are not played or sung all together at the same time, listeners hear the sequence of notes as forming a chord. When an arpeggio also contains passing tones that are not part of the chord, different music theorists may analyze the same musical excerpt differently. Arpeggios enable composers writing for monophonic instruments that play one note at a time (e.g., flute, saxophone, trumpet), to voice chords and chord progressions in musical pieces. Arpeggios and brok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 radio transceivers and older vacuum tube audio systems, guitar amplifiers, 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, 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. Besides sounding annoying, motorboating can cause cl ...

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 platters coated with magnetic material. The platters are paired with 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 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 rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely on ...

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. 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. 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. Due to the complexity a ...

Buffer (computer Science)
In computer science, a data buffer (or just buffer) is a region of a memory used to temporarily store data 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 moving data between processes within a computer. This is 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, pointing at a location in the physical memory. In all cases, the data stored in a data buffer are stored on a physical storage medium. A majority of buffers are implemented in software, which typically use the faster RAM to store temporary data, due to the much faster access time compared with hard disk drives. Buffers are typically used when there is a difference between the rate at which data is received and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
