CDDB
CDDB, short for Compact Disc Database, is a database for application software, 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 Identifier, 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 player (application software), media players and CD ripper software. If a CD is not recognized by a media player (application software), 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 ...

Freedb
Freedb was a database of User-generated content, user-submitted 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 Optical disc authoring#TOC, 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. Freedb was launched in 2001 based on the CDDB (Compact Disc DataBase) after it had been changed to a Proprietary software, proprietary license and renamed "Gracenote". the Freedb 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 Freedb gateway was shut down on March 18, 2019. In 2020, Freedb was shut down by Magix, a German company that had acquired it in 2006. History Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CD Ripper
A CD ripper is software that ripping, extracts raw digital audio in Compact Disc Digital Audio 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 MPEG-1 Audio Layer II, MP2), CD ripping was considered undesirable by copyright holders, with some attempting to retrofit copy protection into the ISO 9660 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. Etymology The Jargon File entry for ''rip'' notes that the term originated in Amiga slang, where it referred to the extraction of multimedia content from program data. Design As an intermediate step, some ripping programs save the extracted audio in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Database
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS 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 application associated with the database. Before digital storage and retrieval of data have become widespread, index cards were used for data storage in a wide range of applications and environments: in the home to record and store recipes, shopping lists, contact information and other organizational data; in business to record presentation notes, project research and notes, and contact information; in schools as flash c ...

Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity sh ... [...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'' that purchased the software, the end users are the employees of the company, who will use the software at work. Context End users are one of the thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fingerprint (computing)
In computer science, a fingerprinting algorithm is a procedure that maps an arbitrarily large data item (remove, as a computer file) to a much shorter bit string, its ''fingerprint'', that uniquely identifies the original data for all practical purposes 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 remove, web browser or proxy server can efficiently check whether a remote, by fetching only its fingerprint and comparing it with that of the previously fetched copy. Fingerprint functions may be seen as high-performance hash functions used to uniquely identify substantial blocks of data where cryptographic functions may be. Special algorithms exist for audio and video fingerpr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
