CD/MP3/WMA Mode Operations
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 compres-
sion to about 12 percent of its initial size with a
high quality sound. 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 Au-
dio, an audio file format developed by Microsoft
Corporation.
