A digital audio player (DAP) is a device that stores, organizes and plays digital music files. It is more commonly referred to as an MP3 player (because of that format's ubiquity), but DAPs often play many additional file formats. Some formats are proprietary, such as Windows Media Audio (WMA), and Advanced Audio Codec (AAC), and, to a degree, MP3. Some of these formats also may incorporate restrictive digital rights management (DRM) technology, such as WMA DRM, which are often part of certain paid download sites. Other formats are completely patent-free or otherwise open, such as Ogg Vorbis, FLAC, Speex (all part of the Ogg open multimedia project), and Module file formats.

There are three main types of digital audio players:

  • MP3 CD Players - Devices that play CDs. Often, they can be used to play both audio CDs and homemade data CDs containing MP3 or other digital audio files.
  • Flash-based Players - These are solid state devices that hold digital audio files on internal or external media, such as memory cards. These are generally low-storage devices, typically ranging from 128MB-4GB, which can often be extended with additional memory. As they are solid state and do not have moving parts, they are very resilient. Such players are generally integrated into USB keydrives.
  • Hard Drive-based Players or Digital Jukeboxes - Devices that read digital audio files from a hard drive. These players have higher capacities, ranging from 1.5GB to 100GB, depending on the hard drive technology. At typical encoding rates, this means that thousands of songs — perhaps an entire music collection — can be stored in one MP3 player. The Apple iPod and Creative Zen are examples of popular digital jukeboxes.

History

The precursors to DAPs were portable CD players and Mini disc players (neither being generally considered a "digital audio player"). Non-mechanical DAPs were introduced following the popularity of the precursors. A compact disc player or CD player is an electronic device to play audio from compact discs. ... The Sony MZ1 MiniDisc player, the first to hit the market in 1992. ...


The first non-mechanical digital audio player in the world was created by SaeHan Information Systems in 1997. The MPMan F10 was later OEMed to the American market through Eiger Labs. The first non-mechanical digital audio player on the American market was the Eiger Labs MPMan F10, a 32MB portable that appeared in the summer of 1998. It was a very basic unit and wasn't user expandable, though owners could upgrade the memory to 64MB by sending the player back to Eiger Labs with a cheque for $69 + $7.95 shipping. EIkeke, notaw gristi MP3 londaw, eta fimie 1998. ...


The second DAP was the Rio PMP300 from Diamond Multimedia, introduced in September 1998. The Rio was a big success during the Christmas 1998 season as sales significantly exceeded expectations, spurring interest and investment in digital music. The Recording Industry Association of America soon filed a lawsuit alleging that the device abetted illegal copying of music, but Diamond won a legal victory on the shoulders of Sony Corp. v. Universal City Studios and digital audio players were ruled legal devices. The Rio PMP-300 portable mp3 player The top view shows the face of the player. ...

Other early DAPs includes Sensory Science's Rave MP2100, the I-Jam IJ-100, and the Creative Labs Nomad. These portables were small and light, but only held enough memory to hold around 7 to 20 songs at normal 128 kbit/s compression rates. They also used slower parallel port connections to transfer files from PC to player, necessary as most PCs then used the Windows 95 and NT operating systems, which did not support the then newer USB connections well enough to be considered for use. When in the year 2000 USB became more common, most (if not all) players adopted the USB standard. Windows 95 (codename Chicago) is a hybrid 16-bit/32-bit graphical user interface-based operating system released on August 24, 1995 by the Microsoft Corporation. ...

By the end of 1999, Compaq made a significant improvement in DAPs' space limitations by using a laptop hard drive for song storage rather than low-capacity flash memory. The Personal Jukebox (PJB-100), manufactured under license by HanGo Electronics, had 4.8GB of storage space, which held about 1200 songs (or 100 CDs, hence the name PJB-100), and was the beginning of what would be called the jukebox segment of digital audio players. This segment eventually became the dominant type of DAP. Compaq was a personal computer company founded in 1982 by Rod Canion, Jim Harris and Bill Murto. ... Typical hard drives of the mid-1990s. ...

The Empeg Car (renamed the Rio Car after it was acquired by SonicBLUE and added to its Rio line of MP3 products) offered players in several capacities ranging from 5GB to 28GB. The unit didn't catch on as SonicBLUE had hoped, however, and was discontinued in the autumn of 2001. empeg Mark 1 unit Rio branded empeg Mark 2a unit The empeg car is the first in-dash MP3 player developed. ...

Equipment

Generally speaking, digital audio players are portable, employing internal or replaceable batteries and headphones, although users often connect players to car and home stereos. Some DAPs also include FM radio tuners and/or microphones for voice recording. Many players can encode audio directly to MP3 or other digital audio formats directly from a line in audio signal.

Usage

As digital audio players have spread, new uses have been found for them.

Even a low-capacity digital audio player can store several hours of podcasts. Podcasting is the distribution of audio or video files, such as radio programs or music videos, over the internet using either RSS or Atom syndication for listening on mobile devices and personal computers. ...


Audio acquisition

Most, if not all, digital audio players can play music that has been ripped from Compact Discs via computer. In addition to ripped CD tracks, many digital audio players can accept downloaded music from online music stores. However, due to the complexity of DRM, not all audio file formats will play on certain digital audio players. Some proprietary audio file formats will also restrict users from transferring songs to non-compatible digital audio players.

Most MOD files are composed by individuals who allow them to be freely distributed, unlike MP3 files ripped from commercial CD tracks. While today's digital audio players generally do not support MOD files directly, progress is being made on that front with projects such as the TRAXMOD [2] digital audio player. For everyone else, it is possible to convert MOD music into MP3 format using software such as Winamp. If this is not the type of module you are looking for, see Module // Modules Module files (MODs) are a class of file formats used to represent music on a computer. ...
