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).
* MPEG Layer-3 audio coding technology licensed from
Fraunhofer IIS and Thomson.
Note: MP3/WMA encoding and writing software is not
supplied with this unit.
