What is MP3 ?

MP3, short for MPEG-1 audio Layer III, is a file format that stores audio files on a
computer. MPEG is an acronym for Moving Picture Experts Group, which is an international
subcommittee that develops standards for digital audio and video compression.
The human hearing range is between 20Hz to 20Khz and it is most sensitive between 2 to 4 KHz.
This MP3 model among other techniques tries to eliminate the frequencies which the human ear is
unable to hear keeping all the hearing frequencies leaving intact the hearing experience.
Through the use of such advanced compression techniques, entire songs can be recorded
and stored for a fraction of the space other wise needed.

MP3’s have provided the means for people to compress their favorite songs at up to
a 12 to 1 compression ratio without loosing the quality of the original recording.
A song that would have been an unwieldy 50 megs in size, would compress into a
neat little package coming in around 4 or 5 megs.

On a CD, each minute of music takes up about 10 megabytes of space.
Very few people would want to download a 40-megabyte file just to hear four
minutes of music. With MP3 compression, the same four-minute song would take up
about four megabytes, and would sound almost as good as the original
