2. Mp3 music files
One of the most popular ways to distribute music
on the Internet is through the use of MP3 music
files. The files use special algorithms that shrink
the size of the files while retaining CD-like quality.
3. Music from CD converts to the MP3
MP3 format so that it can be posted on the Internet . A
typical way to convert the music is to use a ripper a
piece of software that takes the music from the CD
and converts it to MP3 format. The software uses
special algorithms that shrink the size of the file
dramatically so that a typical song is under 3MB and
still maintains high quality. This mix of small size
and high quality is what sets the MP3 standard apart
from other Internet music formats.
4. The Way to Download MP3
● The file converted to an MP3 format is posted to
a site on the Internet
● Someone who wants to download the MP3 file
visit the site and download it to his computer.
5. MP3 and Copyright Protection
● Sometimes MP3 is
considered as a violation of
an artist's copyright. An
example is posting without
the artist's permission.
● As a measure of this
problem, there are some
restrictions for copying
MP3. It is called Digital
Rights Management
(DRM). This image is an
example of a mechanism of
DRM.
