MP3 format can store audio files (sound recordings) on computers and related devices. As audio files are usually quite large, mp3 uses "lossy" compression, which digitally removes parts of the file that are not needed to accurately hear the file. MP3 files approach CDs for sound quality and most people cannot tell the difference. Once a user has downloaded music from CDs and web sites, they can transfer the music files to their mp3 player (Levenstein).
Mostly teenagers embrace MP3 technology today, although people in their 20's and 30's also find the technology attractive. MP3 technology offers something that previous technologies such as the Sony Walkman cannot offer; which is that enable users to download music files directly from websites such as Nap star. No need to go to the nearest music store to buy CDs or tapes. Moreover, MP3 technology allows users to manage his music files according to his taste and concept such as compiling music according to style such as rock, country, gospel, jazz, etc. Moreover, MP3 technology with the aid of a MP3 player allows the user to play music wherever and whenever he wants. MP3 players are replacing walkman and portable CD players rapidly due to its storage capacity and digital sound quality. Most mp3 player's memory can store hundreds of titles. MP3 players usually cost from $ 39 up to 299 depending on its features.
Karlheinz Brandenburg, a German researcher, was one of the inventors of MP3. He first began working on a way of making small sound files some 20 years ago as part of the doctorate thesis. He never projected his work to achieve the fame or infamy it has (MP3 creator speaks out). The MP3 standardized in 1991 by a team of engineers working in the framework of the ISO/IEC MPEG audio committee under the chairmanship of Professor Hans Musmann (University of Hannover - Germany) (MP3). It was designed greatly to reduce the amount of data required to represent audio, yet still sound like a realistic copy of the original uncompressed audio to most listeners.
MPEG-1 Audio Layer 2 encoding began as the Digital Audio Broadcast (DAB) project managed by Egon Meier-Engelen of the DFVLR (later on called DLR = Deutsche Luft und Raumfahrt = German Aerospace Agency) in Germany. This project was financed by the European Union as a part of the EUREKA research program where it was usually known as EU-147. EU-147 ran from 1987 to 1994 (MP3).
On July 7, 1994 the Fraunhofer Society released the first software MP3 encoder called l3enc. The filename extension .mp3 was chosen by the Fraunhofer team on July 14, 1995 (previously, the files had been named .bit) (MP3). With the first real-time software MP3 player Winplay3 (released September 9th, 1995) many people were able to encode and playback MP3 files on their PCs. Because of the moderately small hard drives back in that time ( 500 MB), the technology was necessary to store music for listening enjoyment on a computer (MP3).
In popular usage, MP3 also refers to files of sound or music recordings stored in the MP3 format on computers (MP3). The name is derived from "MPEG-1 Audio Layer 3" more formally known as ISO/IEC 11172-3 Layer 3. The files recorded in this format are saved with the .mp3 filename extension. This extension is also sometimes shared by audio
