MP3/WMA
 
What is MP3?
 
MP3 is an audio compression method and 
classified 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 
compression to about 10 percent of its initial 
size with a high sound quality. 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.
 
What is WMA?
 
WMA is the abbreviation of Windows Media 
Audio, an audio file format developed by 
Microsoft Corporation.
