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] |
Direct Stream Digital
Direct Stream Digital (DSD) is a trademark used by Sony and Philips for their system for digitally encoding audio signals for the Super Audio CD (SACD). DSD uses pulse-density modulation encoding - a technology to store audio signals on digital storage media which are used for the SACD. The signal is stored as delta-sigma modulated digital audio, which is a sequence of single-bit values at a sampling rate of 2.8224 MHz (64 times the CD audio sampling rate of 44.1 kHz, but only at \tfrac of its 16-bit resolution). Noise shaping occurs by use of the 64-times oversampled signal to reduce noise and distortion caused by the inaccuracy of quantization of the audio signal to a single bit. Therefore, it is a topic of discussion whether it is possible to eliminate distortion in one-bit delta-sigma conversion. Development DSD is a method of storing a delta-sigma signal before applying a decimation process that converts the signal to a PCM signal. Delta-sigma conversion wa ...

Optical Disc
In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc that encodes binary data (bits) in the form of pits and lands on a special material, often aluminum, on one of its flat surfaces. Its main uses are physical offline data distribution and long-term archival. Changes from pit to land or from land to pit correspond to a binary value of 1; while no change, regardless of whether in a land or a pit area, corresponds to a binary value of 0. Non-circular optical discs exist for fashion purposes; see shaped compact disc. Design and technology The encoding material sits atop a thicker substrate (usually polycarbonate) that makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data are stored on the disc with a laser or stamping machine, and can be accesse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mbit/s
In telecommunications, data-transfer rate is the average number of bits (bitrate), characters or symbols (baudrate), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s). For example, the data rates of modern residential high-speed Internet connections are commonly expressed in megabits per second (Mbit/s). Standards for unit symbols and prefixes Unit symbol The ISQ symbols for the bit and byte are ''bit'' and ''B'', respectively. In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet. The abbreviation bps is often used to mean bit/s, so that when a ''1 Mbps'' connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per second), or about 0.1192 MiB/s (mebibyte per second).

Areal Density (computer Storage)
Density is a measure of the quantity of information bits that can be stored on a given length (''linear density'') of track, area of surface (''areal density''), or in a given volume (''volumetric density'') of a computer storage medium. Generally, higher density is more desirable, for it allows more data to be stored in the same physical space. Density therefore has a direct relationship to storage capacity of a given medium. Density also generally affects the performance within a particular medium, as well as price. Storage device classes Solid state media Solid state drives use flash memory to store non-volatile media. They are the latest form of mass produced storage and rival magnetic disk media. Solid state media data is saved to a pool of NAND flash. NAND itself is made up of what are called floating gate transistors. Unlike the transistor designs used in DRAM, which must be refreshed multiple times per second, NAND flash is designed to retain its charge state eve ...

Stereophonic Sound
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and internet. Etymology The word ''stereophonic'' derives from the Greek language, Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and i ...

Pulse-code Modulation
Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. Linear pulse-code modulation (LPCM) is a specific type of PCM in which the quantization levels are linearly uniform. This is in contrast to PCM encodings in which quantization levels vary as a function of amplitude (as with the A-law algorithm or the μ-law algorithm). Though ''PCM'' is a more general term, it is often used to describe data encoded as LPCM. A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the sampling rate, which is the number of times per second that samples are taken; and the bit depth, which determines the ...

London Symphony Orchestra
The London Symphony Orchestra (LSO) is a British symphony orchestra based in London. Founded in 1904, the LSO is the oldest of London's orchestras, symphony orchestras. The LSO was created by a group of players who left Henry Wood's Queen's Hall Orchestra because of a new rule requiring players to give the orchestra their exclusive services. The LSO itself later introduced a similar rule for its members. From the outset the LSO was organised on co-operative lines, with all players sharing the profits at the end of each season. This practice continued for the orchestra's first four decades. The LSO underwent periods of eclipse in the 1930s and 1950s when it was regarded as inferior in quality to new London orchestras, to which it lost players and bookings: the BBC Symphony Orchestra and the London Philharmonic Orchestra in the 1930s and the Philharmonia Orchestra, Philharmonia and Royal Philharmonic Orchestra, Royal Philharmonic after the Second World War. The profit-sharing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago Symphony Orchestra
The Chicago Symphony Orchestra (CSO) was founded by Theodore Thomas in 1891. The ensemble makes its home at Orchestra Hall in Chicago and plays a summer season at the Ravinia Festival. The music director is Riccardo Muti, who began his tenure in 2010. The CSO is one of five American orchestras commonly referred to as the " Big Five". History In 1890, Charles Norman Fay, a Chicago businessman, invited Theodore Thomas to establish an orchestra in Chicago. Under the name "Chicago Orchestra," the orchestra played its first concert October 16, 1891 at the Auditorium Theater. It is one of the oldest orchestras in the United States, along with the New York Philharmonic, the Boston Symphony Orchestra and the Saint Louis Symphony Orchestra. Orchestra Hall, now a component of the Symphony Center complex, was designed by Chicago architect Daniel H. Burnham and completed in 1904. Maestro Thomas served as music director for thirteen years until his death shortly after the orchestra' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genesis (band)
Genesis are an English rock band formed at Charterhouse School, Godalming, Surrey, in 1967. The band's most commercially successful line-up consisted of keyboardist Tony Banks, bassist/guitarist Mike Rutherford and drummer/singer Phil Collins. The 1970s line-up, featuring singer Peter Gabriel and guitarist Steve Hackett, was among the pioneers of progressive rock. The group were formed by five Charterhouse pupils, including Banks, Rutherford, Gabriel, and Anthony Phillips, and named by former Charterhouse pupil Jonathan King, who arranged for them to record several singles and their debut album ''From Genesis to Revelation'' in 1968. After splitting from King, the band began touring, signed with Charisma Records and became a progressive rock band on ''Trespass'' (1970). Following Phillips' departure, Genesis recruited Collins and Hackett and recorded ''Nursery Cryme'' (1971). Their live shows began to feature Gabriel's theatrical costumes and performances.

Sacred Love
''Sacred Love'' is the seventh studio album by Sting. The album was released on 29 September 2003. The album featured smoother, R&B-style beats and experiments collaborating with hip-hop artist Mary J. Blige and sitar player Anoushka Shankar. Some songs like "Inside" and "Dead Man's Rope" were well received; and Sting had experimented with new sounds, in particular the more rock-influenced "This War". Sting adapted the first quatrain of William Blake's ''Auguries of Innocence'' for the first four sung lines of "Send Your Love". Sting's collaboration with Blige, "Whenever I Say Your Name", won the Grammy Award for Best Pop Collaboration with Vocals at the 46th Grammy Awards in 2004. The first single "Send Your Love" was also nominated for the Grammy Award for Best Male Pop Vocal Performance, but it lost to " Cry Me a River" by Justin Timberlake. In August 2015, Mylène Farmer and Sting duetted on ''Stolen Car'' and released it as the lead single from Farmer's tenth stud ...

Avalon (Roxy Music Album)
''Avalon'' is the eighth and final studio album by English rock band Roxy Music, released on 28 May 1982 by E.G. Records, and Polydor. It was recorded between 1981 and 1982 at Compass Point Studios in Nassau, Bahamas, and is regarded as the culmination of the smoother, more adult-oriented sound of the band's later work. The first single, " More Than This", preceded the album and was a top 10 hit in Britain, Australia, and several European countries. "Avalon", the second single, reached the top 20; "Take a Chance with Me" reached the top 30. In the United States, "More Than This" and "Take a Chance with Me" reached 103 and 104. ''Avalon'' is Roxy Music's most successful studio album. It stayed at number one on the UK Albums Chart for three weeks, and stayed on the chart for over a year.
