Adat
Alesis Digital Audio Tape, commonly referred to as ADAT, is a magnetic tape format used for the Sound recording and reproduction, recording of eight digital audio tracks onto the same S-VHS tape used by consumer VCRs, and the basis of a series of multitrack recorders by Alesis. Although originally a tape-based format, the term ''ADAT'' later also referred to hard disk recorders like the Alesis ADAT HD24. In 2004, recognizing the ADAT for "beginning a revolution of affordable recording tools," it was inducted into the first-ever TEC Awards TECnology Hall of Fame. History Alesis announced the first ADAT model at the NAMM Show in Anaheim, California in January 1991, with the first ADAT recorders shipping over a year later in February or March 1992. This original ADAT model recorded up to 8 tracks of 16-bit digital audio on a standard S-VHS tape cartridge. Additionally, up to 16 ADATs could be connected to each other to record up to 128 tracks simultaneously with sample-accurate t ...

Digital Audio
Digital audio is a representation of sound recorded in, or converted into, digital signal (signal processing), digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical sampling (signal processing), samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 Hertz, times per second, each with 16-bit audio bit depth, resolution. Digital audio is also the name for the entire technology of sound recording and reproduction using audio signals that have been encoded in digital form. Following significant advances in digital audio technology during the 1970s and 1980s, it gradually replaced comparison of analog and digital recording, analog audio technology in many areas of audio engineering, record production and telecommunications in the 1990s and 2000s. In a digital audio system, an analog signal, analog electrical signal representing the sound is converted with an analog-to-digital converter (ADC) into a digital ...

Audiovisual Introductions In 1992
Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions. Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. The professional audio visual industry has companies that provide hardware, software and services. These organizations are commonly referred to as ''systems integrators'' and perform both the installation and integration of different types of AV equipment from multiple manufacturers into spaces to create the AV experience for the user or audience. Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology. Components Aside from equipment installation, two significant elements of audiovisual are wiring and system control. If either of ...

Digital Recording
In digital recording, an audio signal, audio or video signal is converted into a stream of discrete numbers representing the changes over time in air pressure for audio, or Color, chroma and luminance values for video. This number stream is saved to a storage device. To play back a digital recording, the numbers are retrieved and converted back into their original analog signal, analog audio or video forms so that they can be heard or seen. In a properly matched analog-to-digital converter (ADC) and digital-to-analog converter (DAC) pair, the analog signal is accurately reconstructed, within the constraints of the Nyquist–Shannon sampling theorem, which dictates the sampling rate and quantization error dependent on the Audio bit depth, audio or Bit depth (computer graphics), video bit depth. Because the signal is stored digitally, assuming proper error detection and correction, the recording is not degraded by copying, storage or interference. Timeline *October 3, 1938: ...

Audio Storage
Sound recording and reproduction is the electrical, Mechanical system, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustics, acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multitrack Recording
Multitrack recording (MTR), also known as multitracking, is a method of sound recording developed in 1955 that allows for the separate recording of multiple sound sources or of sound sources recorded at different times to create a cohesive whole. Multitracking became possible in the mid-1950s when the idea of simultaneously recording different audio channels to separate discrete ''tracks'' on the same reel-to-reel tape was developed. A ''track'' was simply a different channel recorded to its own discrete area on the tape whereby their relative sequence of recorded events would be preserved, and playback would be simultaneous or Synchronization, synchronized. A multitrack recorder allows one or more sound sources to different tracks to be simultaneously recorded, which may subsequently be processed and mixed separately. Take, for example, a band with vocals, guitars, a keyboard, bass, and drums that are to be recorded. The singer's microphone, the output of the guitars and keys, ...

Digital Tape Recording System
Digital Tape Recording System (DTRS) is a signal recording and playback medium developed by TASCAM, a division of the TEAC Corporation, that was stored on Hi8 video cassettes. It allowed up to 108 minutes of continuous digital multitrack recording on a single tape. Overview The first device to use the format was the DA-88. This modular, digital multitrack device uses tape as the recording medium and could record up to eight tracks simultaneously. It also allowed multiple DA-88 devices to be combined to record 16 or more tracks. The first models in the series (the TASCAM DA-88, DA-38, DA-98 and Sony PCM-800) recorded at 16-bit resolution. TASCAM later introduced the DA-98HR and DA-78HR, which recorded at 24-bit resolution and sample rates up to 48 kHz (for DA-78HR) and 192 kHz (for DA-98HR, suitable for recording high-resolution audio).

Digital Audio Stationary Head
The Digital Audio Stationary Head or DASH standard is a reel-to-reel, digital audio tape format introduced by Sony in early 1982 for high-quality multitrack studio recording and mastering, as an alternative to analog recording methods. DASH is capable of recording two channels of audio on a quarter-inch tape, and 24 or 48 tracks on tape on open reels of up to 14 inches. The data is recorded on the tape linearly, with a stationary recording head, as opposed to the DAT format, where data is recorded helically with a rotating head, in the same manner as a VCR. The audio data is encoded as linear PCM and boasts strong cyclic redundancy check (CRC) error correction, allowing the tape to be physically edited with a razor blade as analog tape would, e.g. by cutting and splicing, and played back with no loss of signal. In a two-track DASH recorder, the digital data is recorded onto the tape across nine data tracks: eight for the digital audio data and one for the CRC data; there ...

Digital Audio Tape
Digital Audio Tape (DAT or R-DAT) is a signal recording and playback medium developed by Sony and introduced in 1987. In appearance it is similar to a Compact Cassette, using 3.81 mm / 0.15" (commonly referred to as 4 mm) magnetic tape enclosed in a protective shell, but is roughly half the size at 73 mm × 54 mm × 10.5 mm. The recording is digital rather than analog. DAT can record at sampling rates equal to, as well as higher and lower than a CD (44.1, 48, or 32 kHz sampling rate respectively) at 16 bits quantization. If a comparable digital source is copied without returning to the analogue domain, then the DAT will produce an exact clone, unlike other digital media such as Digital Compact Cassette or non- Hi-MD MiniDisc, both of which use a lossy data-reduction system. Like most formats of videocassette, a DAT cassette may only be recorded and played in one direction, unlike an analog compact audio cassette, although many DAT recorders had ...

Phone Connector (audio)
A phone connector is a family of Cylinder, cylindrically-shaped electrical connectors primarily for Analog signal, analog audio signals. Invented in the late 19th century for Telephone switchboard, tele''phone'' switchboards, the phone connector remains in use for interfacing wired audio equipment, such as Headphone, head''phones'', Loudspeaker, speakers, Microphone, micro''phones'', mixing consoles, and electronic musical instruments (e.g. electric guitars, Electronic keyboard, keyboards, and effects units). A Gender of connectors and fasteners, ''male'' connector (a plug), is mated into a ''female'' connector (a socket), though #Other terms, other terminology is used. Plugs have 2 to 5 electrical contacts. The tip contact is indented with a groove. The sleeve contact is nearest the (conductive or Insulator (electricity), insulated) handle. Contacts are insulated from each other by a band of non-conductive material. Between the tip and sleeve are 0 to 3 ring contacts. Since ...
