- An MP3 player is a device for playing MP3 files.The MP3 player is the most recent in an evolution of music formats that have helped consumers enjoy their tunes. Records, 8-track tapes, cassette tapes and CDs -- none of these earlier music formats provide the convenience and control that MP3 players deliver. With an MP3 player in hand or pocket, a consumer can create personalized music lists and carry thousands of songs whereverthey go.
- In the early 1990s, Frauenhofer developed the first, however, unsuccessful MP3 player.WinPlay3 was the first real-time MP3 audio player for PCs running Windows. It was released by Fraunhofer IIS ("Institute for Integrated Circuits"), creators of the MP3 format, on 1995
- In 1997, Advanced Multimedia Products invented the AMP MP3 Playback Engine, the first successful MP3 player. Two university students, Justin Frankel and Dmitry Boldyrev ported AMP to Windows and created Winamp.
- In 1998, Winamp became a free MP3 music player boosting the success of MP3. Until the release of Winamp in 1997, WinPlay3 was the sole option for playing MP3-compressed music on Microsoft Windows.
- MP3 stands for MPEG Audio Layer III and it is a standard for audio compression that makes any music file smaller with little or no loss of sound quality. MP3 is part of MPEG, (Motion Pictures Expert Group), a family of standards for displaying video and audio using lossy compression.
- However it is the German company Fraunhofer-Gesellshaft that releases the license for the music technology.
- Without Data reduction, one second will end up to 1.400 Mbit of stereo music in CD quality. A WAV consisting of a few seconds of sound would be several megabytes in size. By using MPEG audio coding, you may shrink down the original sound data from a CD by a factor of 12, without losing sound quality.
- Although MP3 is perhaps the most well-known file format, there are other file formats that can be played on MP3 players like WMA, WAV, MIDI, AAC, OggVorbis
- ADPCM, ASF, VQF, and ATRAC
- As mp3 became very popular, companies started making portable players. These devices would change the history of the mp3 player. One of the first was MPMan, released in 1998 in South Korea.
- This was followed by the Rio PMP300. In 1999 Compaq created the PJB 100, which could store over 1,200 songs.
- MP3 players use solid-state memory. An MP3 player is no more than a data-storage device with an embedded software application that allows users to transfer MP3 files to the player.
- Specific components may vary, but here are the basic parts of a typical MP3 player:Data port, Memory, Microprocessor, Digital signal processor (DSP), Display, Playback controls, Audio port, Amplifier, Power supply

- This is how the mp3 player works
- MP3 players are as varied as the people who buy them. Choice is based on several factors, including how you plan to use it, the amount of music you want to carry in your MP3 player and how much you are prepared to pay. Let's take a look at the four basic types of MP3 players.
- The flash memory MP3 player is the smallest and lightest and typically stores fewer songs than hard drive players. Because it's small and contains no moving parts, it's ideal for exercisers. And with some models boasting up to 8 GB of storage (2,000 songs) and other models offering video and photo capability, it also appeals to the multimedia aficionado. Its batteries can last up to 28 hours.
- It can store up to 20,000 songs, photographs, data, and video and allow podcast recording. However, these features and the hard drive consume more power, with some batteries lasting eight to 20 hours for music playback and up to six hours for video playback.
- There is a breed of CD players available that plays MP3 and other digital files. These MP3 files are burned to CD-R/RW discs from your old CD collection and used in the MP3 CD player. A CD can hold about 10 hours of music.
- MP3 is no longer just a stand-alone technology. Technology companies are now offering MP3 capability in other consumer products, including satellite radios, personal digital assistants, DVD players, sunglasses, swim goggles and even a combination Swiss Army Knife-MP3 player.
- Around 2003 mp3 players and cell phones were combined for the first time. It was also around the time that artists started selling music as mp3 downloads. Eventually this would start a trend that continues to this day. The history of the mp3 player is an exciting one and it continues to evolve. The technology is advancing, improving the quality of the sound even more.
