CDDB
CDDB, short for Compact Disc Database, is a database for software applications to look up audio CD (compact disc) information over the Internet. This is performed by a client which calculates a (nearly) unique disc ID and then queries the database. As a result, the client is able to display the artist name, CD title, track list and some additional information. CDDB is a licensed trademark of Gracenote, Inc. The database is used primarily by media players and CD ripper software. If a CD is not recognized by a media player or CD ripper it can be added to the database if the user fills in the names and artists etc. in a media player such as iTunes or MusicMatch Jukebox. The need for CDDB is a direct consequence of the original design of the CD, which was conceived as an evolution of the gramophone record, and did not consider the audio tracks as data files to be identified and indexed. The audio CD format does not include the disc name or track names, so a supplemental database ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gracenote
Gracenote, Inc. is a company owned by Nielsen Holdings that provides music, video and sports metadata and automatic content recognition (ACR) technologies to entertainment services and companies, worldwide. Formerly CDDB ("Compact Disc Data Base"), Gracenote maintains and licenses an Internet-accessible database containing information about the contents of audio compact discs and vinyl records. History Gracenote began in 1993 as an open-source project involving a CD player program named xmcd and an associated database named CDDB. xmcd and CDDB were created by Ti Kan and Steve Scherf. Because CDs do not contain any digitally-encoded information about their contents, Kan and Scherf devised a technology that identifies and looks up CDs based on TOC information stored at the beginning of each disc. A TOC, or Table of Contents, is a list of offsets corresponding to the start of each track on a CD. Its original database was created from and continues to receive voluntary contribut ...

Freedb
Freedb was a database of compact disc track listings, where all the content was under the GNU General Public License. To look up CD information over the Internet, a client program calculated a hash function from the CD table of contents and used it as a disc ID to query the database. If the disc was in the database, the client was able to retrieve and display the artist, album title, track list and some additional information. It was originally based on the now-proprietary CDDB (Compact Disc DataBase). Because it inherited the CDDB limitations, there is no data field in the Freedb database for composer. This limits its usefulness for classical music CDs. Furthermore, CDs in a series are often introduced in the database by different people, resulting in inconsistent spelling and naming conventions across discs. the database held just under 2,000,000 CDs. As of 2007, MusicBrainz – a project with similar goals – had a Freedb gateway that allowed access to their own database. The ...

CD Ripper
A CD ripper, CD grabber, or CD extractor is software that rips raw digital audio in Compact Disc Digital Audio (CD-DA) format tracks on a compact disc to standard computer sound files, such as WAV or MP3. A more formal term used for the process of ripping audio CDs is digital audio extraction (DAE). History In the early days of computer CD-ROM drives and audio compression mechanisms (such as MP2), CD ripping was considered undesirable by copyright holders, with some attempting to retrofit copy protection into the simple ISO9660 standard. As time progressed, most music publishers became more open to the idea that since individuals had bought the music, they should be able to create a copy for their own personal use on their own computer. This is not yet entirely true; even with some current digital music delivery mechanisms, there are considerable restrictions on what an end user can do with their paid for (and therefore personally licensed) audio.

Database
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Four Seasons (Vivaldi)
''The Four Seasons'' ( it, Le quattro stagioni) is a group of four violin concertos by Italian composer Antonio Vivaldi, each of which gives musical expression to a season of the year. These were composed around 1718−1720, when Vivaldi was the court chapel master in Mantua. They were published in 1725 in Amsterdam, together with eight additional concerti, as (''The Contest Between Harmony and Invention''). ''The Four Seasons'' is the best known of Vivaldi's works. Though three of the concerti are wholly original, the first, "Spring", borrows patterns from a sinfonia in the first act of Vivaldi's contemporaneous opera ''Il Giustino''. The inspiration for the concertos is not the countryside around Mantua, as initially supposed, where Vivaldi was living at the time, since according to Karl Heller they could have been written as early as 1716–1717, while Vivaldi was engaged with the court of Mantua only in 1718. They were a revolution in musical conception: in them Vivaldi r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vivaldi
Antonio Lucio Vivaldi (4 March 1678 – 28 July 1741) was an Italian composer, virtuoso violinist and impresario of Baroque music. Regarded as one of the greatest Baroque composers, Vivaldi's influence during his lifetime was widespread across Europe, giving origin to many imitators and admirers. He pioneered many developments in orchestration, violin technique and programatic music. He consolidated the emerging concerto form into a widely accepted and followed idiom, which was paramount in the development of Johann Sebastian Bach's instrumental music. Vivaldi composed many instrumental concertos, for the violin and a variety of other musical instruments, as well as sacred choral works and more than fifty operas. His best-known work is a series of violin concertos known as '' the Four Seasons''. Many of his compositions were written for the all-female music ensemble of the '' Ospedale della Pietà'', a home for abandoned children. Vivaldi had worked as a Catholi ...

European Classical Music
Classical music generally refers to the art music of the Western world, considered to be distinct from Western folk music or popular music traditions. It is sometimes distinguished as Western classical music, as the term "classical music" also applies to non-Western art music. Classical music is often characterized by formality and complexity in its musical form and harmonic organization, particularly with the use of polyphony. Since at least the ninth century it has been primarily a written tradition, spawning a sophisticated notational system, as well as accompanying literature in analytical, critical, historiographical, musicological and philosophical practices. A foundational component of Western Culture, classical music is frequently seen from the perspective of individual or groups of composers, whose compositions, personalities and beliefs have fundamentally shaped its history. Rooted in the patronage of churches and royal courts in Western Europe, surviving ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
End-user
In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrators, database administrators, Information technology (IT) experts, software professionals and computer technicians. End users typically do not possess the technical understanding or skill of the product designers, a fact easily overlooked and forgotten by designers: leading to features creating low customer satisfaction. In information technology, end users are not "customers" in the usual sense—they are typically employees of the customer. For example, if a large retail corporation buys a software package for its employees to use, even though the large retail corporation was the "customer" which purchased the software, the end users are the employees of the company, who will use the software at work.

Fingerprint (computing)
In computer science, a fingerprinting algorithm is a procedure that maps an arbitrarily large data item (such as a computer file) to a much shorter bit string, its fingerprint, that uniquely identifies the original data for all practical purposesA. Z. Broder. Some applications of Rabin's fingerprinting method. In Sequences II: Methods in Communications, Security, and Computer Science, pages 143--152. Springer-Verlag, 1993 just as human fingerprints uniquely identify people for practical purposes. This fingerprint may be used for data deduplication purposes. This is also referred to as file fingerprinting, data fingerprinting, or structured data fingerprinting. Fingerprints are typically used to avoid the comparison and transmission of bulky data. For instance, a web browser or proxy server can efficiently check whether a remote file has been modified, by fetching only its fingerprint and comparing it with that of the previously fetched copy.Detecting duplicate and near-duplicate ...
