MP3, those three figures stand for a new generation of music consumption. Changed into digital data, oodles of ear candies were packed, transmitted via Internet and saved on computers, CDs and memory cards. To hear Music via pc or via small and portable music players: MP3 promises cool sound to churn out.
MP3 is the shortcut for MPEG 2.5, Audio Layer 3 Standard and denotes a method to compress digital audio data. Simple verbalised, inaudible sound signals were leaved out or overlayed through others. The residual data will be packed, that it only takes 10 % of the actual storage space. With MP3, Music could be compressed and saved with the quality like a CD.
The beginning
Beginning of the 80's
Basics in coding speech and music were developed at the University Erlangen-Nuremberg. In cooperation with the Fraunhofer ISS, the audio coding scheme arises.
1987
The Fraunhofer ISS succeeds to code stereo signals in real time.
1992
The "Audiogruppe der Moving-Picture Expert Group" standardizes the audio encoding system as ISO / MPEG Layer-3 and gives them the shortcut "MP3".
In the middle of the 90's
the Bavarian scientists publish their patent in internet. US-Students are the first, who use the technique to exchange music via internet.
1998
the company "Saehan Information Systems" launches the first MP3-Player named "MPMan".
today
well-known producer offer radios with integrated decoder to receive radio transmission, digital and MP3-encoded. Radios, suitable to record music, is in development.
As the successor of the MP3-standard the MP4-standard has been established. The MP4-standard includes multimedia content like audio, video dates, subtitles 2D, 3D graphics and pictures.
MP3 - Technical Basics
The MP3 audio encoding is a method to pack digitised songs to the tenth part of their original dimension without distinguishable loss in the sound quality.
The compression of the data bases on psycho-acoustic viewpoints. Only frequencies which are not hearable, were filtered. Furthermore, the ear could notice the full acoustic noice only a few minutes later. So you could filter the not hearable sounds in this phase. The frequency separation and the signal-to-noise ratio rest unmodified.
For example Song with a length of 3 minutes needs disc space of 30 MB on a CD. Saved as MP3 file, the largeness of the same song is 3 MB. For comparison: a CD contains music for 74 minutes in "normal" form, but in MP3 it could back up music for 11 hours. Furthermore MP3 allows acceptable loading time for the transfer of audio data via internet.
With MP3 encoded hits, streaming is possible, namely, to hear music during the download phase. The condition is, that the bitrate, which is 128 Kbps in good music quality, is not higher than the speed of the internet connexion.
