Gold CD
A gold compact disc is one in which gold is utilized in place of the high-purity aluminium or silver commonly used as the reflective coating on ordinary CDs and CD-Rs respectively. Gold disks are available as both CDs and CD-Rs as well, and are compatible with standard players and recorders. The advantage of the gold reflection layer lies in its corrosion resistance. As such, gold CDs were seen as a potential solution to the incidence of CD rot on early CDs (mainly manufactured by PDO UK). In 2014, Audio Fidelity, an American publisher of audiophile CDs, announced that it was abandoning the gold format and moving to the hybrid Super Audio CD (SACD) format for future releases.

Extended Resolution Compact Disc
Extended Resolution Compact Disc (XRCD) is a mastering and manufacture process patented by JVC (Victor Company of Japan, Ltd) for producing Red Book compact discs. It was first introduced in 1995. An XRCD is priced about twice as high as a regular full-priced CD. JVC attributes this to the higher cost of quality mastering and manufacturing. Technical overview The XRCD definition refers to the mastering and manufacture process; the resulting CD and the contained data conform to the redbook standard and are encoded at 16 bits, 44.1 kHz. Hence, XRCDs are playable on any compact disc player. JVC uses advanced dither algorithms (though without noise shaping) in their K2 technology to transfer the analog or digital source to physical disc. The company claims to have studied how inferior CD-remastering techniques degrade the master tape sound and strives to minimize this loss. Unlike HDCD, the extra four bits cannot be recovered, as this method of mastering only aims to improv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Fidelity Sound Lab
Mobile Fidelity Sound Lab (MFSL or MoFi) is a record label that specialized in the production of audiophile issues. The company produces reissued vinyl LP records, compact discs, and Super Audio CDs and other formats. History Recording engineer Brad Miller (1939–1998) released the first recordings on the Mobile Fidelity label in March 1958, a recording of a Southern Pacific steam locomotive. Later LPs included other steam trains, environmental sounds and orchestral music, and a few pop and orchestral recordings. In 1977 Mobile Fidelity Sound Labs was founded and began releasing Original Master Recording LPs, using a half-speed mastering process. From 1985-1992, MoFi sourced recordings from the Soviet Union’s Melodiya Records archives. In November 1999, Mobile Fidelity Sound Lab shut down after the bankruptcy of M. S. Distributing. In 2001 MFSL's assets were acquired by Jim Davis of Music Direct. Products LPs In 1977, Mobile Fidelity began to produce a line of recor ...

Audiophile
An audiophile (from + ) is a person who is enthusiastic about high-fidelity sound reproduction. The audiophile seeks to achieve high sound quality in the audio reproduction of recorded music, typically in a quiet listening space in a room with good acoustics. Audiophile values may be applied at all stages of music reproduction—the initial audio recording, the production process, the storage of sound data, and the playback (usually in a home setting). In general, the values of an audiophile are seen to be antithetical to the growing popularity of more convenient but lower-quality music, especially lossy digital file types like MP3, lower-definition music streaming services, laptop or cell phone speakers, and low-cost headphones. The term '' high-end audio'' refers to playback equipment used by audiophiles, which may be bought at specialist shops and websites. High-end components include turntables, digital-to-analog converters, equalization devices, preamplifiers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Album
Music recording certification is a system of certifying that a music recording has shipped, sold, or streamed a certain number of units. The threshold quantity varies by type (such as album, single, music video) and by nation or territory (see List of music recording certifications). Almost all countries follow variations of the RIAA certification categories, which are named after precious materials (gold, platinum and diamond). The threshold required for these awards depends upon the population of the territory where the recording is released. Typically, they are awarded only to international releases and are awarded individually for each country where the album is sold. Different sales levels, some perhaps 10 times greater than others, may exist for different music media (for example: videos versus albums, singles, or music download). History The original gold and silver record awards were presented to artists by their own record companies to publicize their sales achie ...

CD Rot
Disc rot is the tendency of compact disc, CD, DVD, or other optical discs to become unreadable because of chemical deterioration. The causes include oxidation of the reflective layer, reactions with contaminants, ultra-violet light damage, and de-bonding of the adhesive used to adhere the layers of the disc together. Causes In CDs, the reflective layer is immediately beneath a thin protective layer of lacquer, and is also exposed at the edge of the disc. The lacquer protecting the edge of an optical disc can usually be seen without magnification. It is rarely uniformly thick; thickness variations are usually visible. The reflective layer is typically aluminium, which reacts easily with several commonly encountered chemicals such as oxygen, sulfur, and certain Ion, ions carried by liquid water. In ordinary use, a surface layer of aluminium oxide is formed quickly when an aluminium surface is exposed to the atmosphere; it serves as Passivation (chemistry), passivation for the bulk alu ...

Remaster
A remaster is a change in the sound or image quality of previously created forms of media, whether Mastering (audio), audiophonic, Cinematography, cinematic, or Videography, videographic. The resulting product is said to be remastered. The terms digital remastering and digitally remastered are also used. In a wider sense, remastering a product may involve other, typically smaller inclusions or changes to the content itself. They tend to be distinguished from remakes, based on the original. Mastering A master recording is the definitive recording version that will be replicated for the end user, commonly into other formats (e.g. LP records, Magnetic tape, tapes, Compact disc, CDs, DVDs, Blu-rays, etc.). A batch of copies is often made from a single original master recording, which might itself be based on previous recordings. For example, sound effects (e.g. a door opening, punching sounds, falling down the stairs, a bell ringing) might have been added from copies of sound e ...

Super Audio CD
Super Audio CD (SACD) is an optical disc format for audio storage introduced in 1999. It was developed jointly by Sony and Philips Electronics and intended to be the successor to the compact disc (CD) format. The SACD format allows multiple audio channels (i.e. surround sound or multichannel sound). It also provides a higher bit rate and longer playing time than a conventional CD. An SACD is designed to be played on an SACD player. A hybrid SACD contains a Compact Disc Digital Audio (CDDA) layer and can also be played on a standard CD player. History The Super Audio CD format was introduced in 1999, and is defined by the ''Scarlet Book'' standard document. Philips and Crest Digital partnered in May 2002 to develop and install the first SACD hybrid disc production line in the United States, with a production capacity of up to three million discs per year. SACD did not achieve the level of growth that compact discs enjoyed in the 1980s, and was not accepted by the mainstr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compact Disc Bronzing
Compact disc bronzing, or CD bronzing, is a specific, uncommon variant of disc rot, a type of corrosion that affects the reflective layer of compact discs and renders them unreadable over time. The phenomenon was first reported by John McKelvey in the September/October 1994 issue of ''American Record Guide''. John McKelvey, American Record Guide, pg. 73, September 1994 Affected discs show an uneven brownish discolouring that usually starts at the edge of the disc and slowly works its way toward the center. The top or label layer is affected before the bottom layer. The disc becomes progressively darker over time; tracks at the end of the disc (near the outer edge) show an increasing number of disc-read errors before becoming unplayable. CD bronzing seems to occur mostly with audio CDs manufactured by Philips and Dupont Optical (PDO) at its plant in Blackburn, Lancashire, UK, between the years 1988 and 1993. Most, but not all, of these discs have "Made in U.K. by PDO" etched into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD Player
A CD player is an electronic device that plays audio compact discs, which are a digital audio, digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music or audiobooks. CD players may be part of home stereo systems, car audio systems, personal computers, or portable CD players such as CD boomboxes. Most CD players produce an output signal via a headphone jack or RCA jacks. To use a CD player in a home stereo system, the user connects an RCA cable from the RCA jacks to a hi-fi (or other power amplifier, amplifier) and loudspeakers for listening to music. To listen to music using a CD player with a headphone output jack, the user plugs headphones or earphones into the headphone jack. Modern units can play audio formats other than the original CD PCM audio coding, such as MP3, Advanced Audio Coding, AAC and Windows Media Audio, WMA. DJs playing dance music at clubs often use specialize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
