MP3/WMA Player

What is MP3/WMA?
MP3 (MPEG Audio Layer-3) and WMA (Windows Media
TM
Audio) are the compression formats of digital audio. The
former is developed by MPEG (Motion Picture Experts
Group), and the latter is developed by Microsoft
Corporation. Using these compression formats, you can
record the contents of about 10 music CDs on a single
CD media (This figures refer to data recorded on a 650
MB CD-R or CD-RW at a fixed bit rate of 128 kbps and a
sampling frequency of 44.1 kHz).
Note: MP3/WMA encoding and writing software is not
supplied with this unit.
