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 650MB CD-R or CD-RW at a fixed bit rate of 128 kbps and a sampling frequency of 44.1 kHz).
Notes:
¡
MP3/WMA encoding and writing software is not supplied with this unit.
¡
CD writing software is not supplied with this unit.
Points to remember when making MP3/WMA files

High bit rate and high sampling frequency are recom-
mended for high quality sounds.
¡
Selecting VBR (Variable Bit Rate) is not recommended
because playing time is not displayed properly and sound
may be skipped.
¡
The playback sound quality differs depending on the
encoding circumstances. For details, refer to the user
manual of your own encoding software and writing soft-
ware.

Recording MP3/WMA files on a CD-media
¡
You are recommended to minimize the chances of mak-
ing a disc that contains both CD-DA files and MP3/WMA
files.
¡
If CD-DA files are on the same disc as MP3 or WMA
files, the songs may not play in the intended order, or
some songs may not play at all.
¡
When storing MP3 data and WMA data on the same
disc, use different folders for each data.
¡
Do not record files other than MP3/WMA files and unnec-
essary folder on a disc.
¡
The name of MP3/WMA file should be added by rules as
shown in the following descriptions and also comply with
the rules of each file system.
¡
You may encounter trouble in playing MP3/WMA files or
displaying the information of MP3/WMA files recorded
with certain writing software or CD recorders.
¡
The file extension “mp3” or “wma” should be assigned to
each file depending on the file format.
¡
This unit does not have the play list function.
¡
Although Multi-session recording is supported, the use of
Disc-at-Once is recommended.
