When the digital audio player market was taking off, MP3 was widely adopted as the standard hence the popular name "MP3 player". Sony was an exception and used their own ATRAC codec taken from their MiniDisc format, which Sony claimed was better. [ 123 ]
Karlheinz Brandenburg (born 20 June 1954) is a German electrical engineer and mathematician. [1] Together with Ernst Eberlein, Heinz Gerhäuser (former Institutes Director of Fraunhofer IIS), Bernhard Grill, Jürgen Herre and Harald Popp (all Fraunhofer IIS), he developed the widespread MP3 method for audio data compression.
MP3 CD/DVD players: Portable CD players that can decode and play MP3 audio files stored on CDs. Such players were typically a less expensive alternative than either the hard drive or flash-based players when the first units of these were released. The blank CD-R media they use is inexpensive.
The first portable CD player released was the D-50 by Sony. [58] The D-50 was made available on the market in 1984, [59] and adopted for Sony's entire portable CD player line. In 1998, portable MP3 players began to compete with portable CD players.
An audio format is a medium for sound recording and reproduction. The term is applied to both the physical recording media and the recording formats of the audio content —in computer science it is often limited to the audio file format , but its wider use usually refers to the physical method used to store the data.
The CD+G format takes advantage of the channels R through W. These six bits store the graphics information. CD + Extended Graphics (CD+EG, also known as CD+XG) is an improved variant of the Compact Disc + Graphics (CD+G) format. Like CD+G, CD+EG uses basic CD-ROM features to display text and video information in addition to the music being played.

Discs are written in the "Yellow Book" standard data format (used for CD-ROMs and DVD-ROMs), as opposed to the Red Book standard audio format (used for CD-DA audio CDs).
The development of the MP3 audio file format, and legal issues involved in copying such files, has driven most of the innovation in music distribution since their introduction in the late 1990s. As hard disk capacities and computer CPU speeds increased at the end of the 1990s, hard disk recording became more popular. As of early 2005 hard disk ...
