What is MP3/WMA?
Common
≥
High bit rate and high sampling frequency are
recommended for high quality sounds.
≥
Selecting VBR (Variable Bit Rate) is not recom-
mended 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 software.
MP3
≥
It is recommended to set the bit rate to “128 kbps
or more” and “fixed”.
WMA
≥
It is recommended to set the bit rate to “64 kbps
or more” and “fixed”.
≥
Do not set the copy protect attribute on the WMA
file to enable this unit to playback.
Caution:
≥
Never assign the “.mp3”, or “.wma” file name extension to a file that is not in the MP3/WMA format.
This may not only produce noise from the speaker damage, but also damage your hearing.

You are recommended to minimize the chances
of making 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 in-
tended 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
unnecessary 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.

Recording MP3/WMA files on a CD-media
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 sin-
gle 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 are not supplied with this unit.
≥
CD writing software is not supplied with this unit.
