Amarok (audio)
Amarok is a free and open-source music player. It is available for Unix-like, as well as for Windows and macOS systems. Although Amarok is part of the KDE project, it is released independently of the central KDE Software Compilation release cycle. Amarok is released under the terms of the GPL-2.0-or-later. History The project was originally started by Mark Kretschmann as a means of improving XMMS due to several usability problems, which interfered with the addition of new files to the playlist due to several user interface elements existing for one task. The original amaroK was created based upon the idea of a two-pane interface seen in Midnight Commander, and the first version of the software released solely by Kretschmann, was based upon the ideal of allowing users to drag-and-drop music into an interface in which the playlist was displayed on the right and information on the left. After the initial release of AmaroK, several developers joined the project to form the †... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qt (software)
Qt (pronounced "cute") is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open-source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses. Purposes and abilities Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a ''widget toolkit''. ...

Advanced Audio Coding
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate. AAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications.ISO (2006ISO/IEC 13818-7:2006 - Information technology -- Generic coding of moving pictures and associated audio information -- Part 7: Advanced Audio Coding (AAC), Retrieved on 2009-08-06ISO (2006, Retrieved on 2009-08-06 Part of AAC, HE-AAC ("AAC+"), is part of MPEG-4 Audio and is adopted into digital radio standards DAB+ and Digital Radio Mondiale, and mobile television standards DVB-H and ATSC-M/H. AAC supports inclusion of 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 16 low frequency effects ( LFE, limited to 120 Hz) channels, up to 16 "coupling" or dialog channels, and up to 16 data streams.

Creative NOMAD
The NOMAD was a range of digital audio players designed and sold by Creative Technology Limited, and later discontinued in 2004. Subsequent players now fall exclusively under the MuVo and ZEN brands. The NOMAD series consisted of two distinct brands: * ''NOMAD'' (and later ''NOMAD MuVo'') - Players that use flash memory. This brand eventually became the MuVo line. * ''NOMAD Jukebox'' - Players that use microdrives. The brand evolved into the ''ZEN'' line. NOMAD and NOMAD MuVo These models appear as a USB mass storage device to the operating system so that the device can be accessed like any other removable disk, a floppy disk for example. Older MuVo devices and all Jukebox models use a custom protocol named PDE (''Portable Digital Entertainment'', a Creative internal device designation) that requires the installation of drivers before the device can be recognised by the operating system. Creative's foray into the MP3 player market began with the ''Creative NOMAD'', a rebrande ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IPod
The iPod is a discontinued series of portable media players and multi-purpose mobile devices designed and marketed by Apple Inc.

Ogg Vorbis
Vorbis is a free and open-source software project headed by the Xiph.Org Foundation. The project produces an audio coding format and software reference encoder/decoder (codec) for lossy audio compression. Vorbis is most commonly used in conjunction with the Ogg container format and it is therefore often referred to as Ogg Vorbis. Vorbis is a continuation of audio compression development started in 1993 by Chris Montgomery. Intensive development began following a September 1998 letter from the Fraunhofer Society announcing plans to charge licensing fees for the MP3 audio format. The Vorbis project started as part of the Xiphophorus company's Ogg project (also known as OggSquish multimedia project). Chris Montgomery began work on the project and was assisted by a growing number of other developers. They continued refining the source code until the Vorbis file format was frozen for 1.0 in May 2000. Originally licensed as LGPL, in 2001 the Vorbis license was changed to the BSD li ...

Digital Rights Management
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures (TPM) such as access control technologies can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification, and distribution of copyrighted works (such as software and multimedia content), as well as systems that enforce these policies within devices. Laws in many countries criminalize the circumvention of DRM, communication about such circumvention, and the creation and distribution of tools used for such circumvention. Such laws are part of the United States' Digital Millennium Copyright Act (DMCA), and the European Union's Information Society Directive (the French DADVSI is an example of a member state of the European Union implementing the directive). DRM techniques include licensing agreements and encryption. The industry has expanded the usage of DRM to various hardware products, such as K ...
