What
is
MP3?
MP3 is
an
audio compression method and
is
classified as audio layer 3 of the MPEG
standard.
This audio compression method has gained
ground into PC users and Become a standard
format.
This MP3 features original audio data
compression to about 10 percent of its initial
size while keeping high sound quality intact.
This means that about 10 music CDs can be
recorded
on
a CD-R disc or CD-RW disc to
allow a long listening time without having to
change CDs.
