What is MP3?
MP3 is an audio compression method and clas-
sified into audio layer 3 of MPEG standards.
This audio compression method has penetrated
into PC users and become a standard format.
This MP3 features the original audio data com-
pression to about 10 percent of its initial size
with a high sound quality. This means about 10
music CDs can be recorded on a CD-R disc or
CD-RW disc to allow a long listening time with-
out having to change CDs.

WMA is the abbreviation of Windows Media Au-
dio, an audio file format developed by Microsoft
