ATRAC
Adaptive Transform Acoustic Coding (ATRAC) is a family of proprietary audio compression algorithms developed by Sony. MiniDisc was the first commercial product to incorporate ATRAC, in 1992. ATRAC allowed a relatively small disc like MiniDisc to have the same running time as a CD while storing audio information with minimal perceptible loss in quality. Improvements to the codec in the form of ATRAC3, ATRAC3plus, and ATRAC Advanced Lossless followed in 1999, 2002, and 2006 respectively. Files in ATRAC3 format originally had the extension; however, in most cases, the files would be stored in an OpenMG Audio container using the extension . Previously, files that were encrypted with OpenMG had the extension, which was replaced by starting in SonicStage v2.1. Encryption is no longer compulsory as of v3.2. Other MiniDisc manufacturers such as Sharp and Panasonic also implemented their own versions of the ATRAC codec. History ATRAC was developed for Sony's MiniDisc format. ATR ...

ATRAC CD
An ATRAC CD is a compressed audio optical disc containing audio compression (data), compressed digital audio in the ATRAC3 or ATRAC3plus formats, which are part of Sony's ATRAC (Adaptive Transform Acoustic Coding) family of proprietary audio compression algorithms. Description ATRAC CD was used with SonicStage Simple Burner software (Ver.1.0 / 1.1) in February 2003, and was subsequently replaced with SonicStage in 2004. The new Discman, CD Walkman product was called "ATRAC CD Walkman". In the following year (2004-2005), ATRAC CD boombox was introduced, as a new product. Software for burning ATRAC CD The ATRAC CD can be burned with SonicStage Simple Burner Ver.1.1, SonicStage 2.x to 3.x and SonicStage CP. This software is able to create a disk image from MP3 files and compact discs and can be Optical disc authoring, burned with the included Optical disc drive, CD-R/RW drive on a computer.

MiniDisc
MiniDisc (MD) is an erasable magneto-optical disc-based data storage format offering a capacity of 60, 74, or 80 minutes of digitized audio. Sony announced the MiniDisc in September 1992 and released it in November of that year for sale in Japan and in December in Europe, North America, and other countries. The music format was based on ATRAC audio data compression, Sony's own proprietary compression code. Its successor, Hi-MD, would later introduce the option of linear PCM digital recording to meet audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan and found moderate success in Europe. Although it was designed to succeed the cassette tape, it did not manage to supplant it globally. By March 2011, Sony had sold 22 million MD players, but discontinued further development. Sony ceased manufacturing and sold the last of the players by March 2013. On January 23, 2025, Sony announced they would end the production of recordable MD media ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SonicStage
SonicStage is a discontinued software product from Sony that is used for managing portable devices when they are plugged into a computer running Microsoft Windows. It comprises a music player and library manager, similar to iTunes, Windows Media Player and RealPlayer. It is used to manage the library of ATRAC (.omg and .oma) and MP3 recordings on a PC.

OpenMG
OpenMG is a digital rights management (DRM) system developed by Sony for managing and protecting digital music data on a personal computer. It was originally designed for audio files in ATRAC3 format; the compliant software, e.g. Sony SonicStage, is usually capable of transcoding MP3 and WAV files to OpenMG/ATRAC3. The file extensions OpenMG-encrypted files use are and . Sister technologies OpenMG Light (for mobile devices) and OpenMG X were also created. Development OpenMG was created alongside MagicGate in an effort to protect digital music copyright. It was released alongside the Memory Stick Walkman and VAIO Music Clip. It is compliant with the Secure Digital Music Initiative (SDMI) version 1.0 industry group specification formed in February 1999. There has been at least one reported case when a security update of Windows XP and Windows 2000 broke OpenMG-compliant software. This issue was later resolved. Method Audio files encrypted using OpenMG cannot be played on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio File Format
An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or audio compression (data), compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is usually embedded in a container format or an audio data format with defined storage layer. Format types It is important to distinguish between the audio coding format, the Container format (digital), container containing the Raw audio format, raw audio data, and an audio codec. A codec performs the encoding and decoding of the raw audio data while this encoded data is (usually) stored in a container file. Although most audio file formats support only one type of audio coding data (created with an audio codec, audio coder), a multimedia container format (as Matroska or Audio Video Interleave, AVI) may support multiple ...

Sony Dynamic Digital Sound
is a cinema sound system developed by Sony, in which compressed digital sound information is recorded on both outer edges of the 35mm film release print. The system supports up to eight independent channels of sound: five front channels, two surround channels and a single sub-bass channel. The eight channel arrangement is similar to large format film magnetic sound formats such as Cinerama and Cinemiracle. The five front channels are useful for very large cinema auditoriums where the angular distance between center and left/right channels may be considerable. SDDS decoders provide the ability to downmix to fewer channels if required. History Although originally slated to premiere with 1991's ''Hook'', the SDDS project was delayed and instead premiered on April 2, 1992. and on June 17, 1993 premiered it First Film Last Action Hero. Since then, over 2000 movies have been mixed and remastered in Sony Dynamic Digital Sound, and as early as 1999 over 6,750 movie theaters were ...

Walkman
is a brand of Personal stereo, portable audio players manufactured by Sony since 1979. It was originally introduced as a portable Compact Cassette, cassette player and later expanded to include a range of portable audio products. Since 2011, the brand has referred exclusively to digital flash memory players. The Walkman became widely popular during the 1980s for its portable design and private listening experience. It influenced popular culture by promoting individualized music consumption and supporting activities such as aerobics. Its widespread use gave rise to the "Walkman effect," a term describing how portable music devices and headphones allow listeners to control their sonic environment. In 1986, "Walkman" was added to the Oxford English Dictionary, and in some markets the term became a genericized trademark for portable audio players. The Walkman also contributed to the widespread adoption of the Compact Cassette format, which surpassed vinyl record sales in 1983. Son ...

Dolby Digital
Dolby Digital, originally synonymous with Dolby AC-3 (see below), is the name for a family of audio compression technologies developed by Dolby Laboratories. Called Dolby Stereo Digital until 1995, it is lossy compression (except for Dolby TrueHD). The first use of Dolby Digital was to provide digital sound in cinemas from 35 mm film prints. It has since also been used for TV broadcast, radio broadcast via satellite, digital video streaming, DVDs, Blu-ray discs and game consoles. Dolby AC-3 was the original version of the Dolby Digital codec. The basis of the Dolby AC-3 multi-channel audio coding standard is the modified discrete cosine transform (MDCT), a lossy audio compression algorithm. It is a modification of the discrete cosine transform (DCT) algorithm, which was proposed by Nasir Ahmed in 1972 for image compression. The DCT was adapted into the MDCT by J.P. Princen, A.W. Johnson and Alan B. Bradley at the University of Surrey in 1987. Dolby Laboratories adap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
