What is MP3/WMA?
MP3 (MPEG audio layer 3) and WMA (Windows
Media™ 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. (These
fi gures refer to data recorded on a 650 MB CD-R
or CD-RW at a fi xed 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.
≥
CD writing software is not supplied with this unit.
Points to Remember
When Making MP3/WMA Files
Common:
≥
High bit rate and high sampling frequency are
recommended 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 software.
MP3:
≥
It is recommended to set the bit rate to “128 kbps
or more” and “fi xed”.
WMA:
≥
It is recommended to set the bit rate to “64 kbps
or more” and “fi xed”.
≥
Do not set the copy protect attribute on the WMA
fi le to enable this unit to playback.

Notes on MP3/WMA
Caution:
≥
Never assign the “.mp3”, or “.wma” fi le
name extension to a fi le that is not in the
MP3/WMA format. This may not only produce
noise from the speaker damage, but also
damage your hearing.

Recording MP3/WMA Files
on a CD-Media
≥
You are recommended to minimize the chances
of making a disc that contains both CD-DA fi les
and MP3/WMA fi les.
≥
If CD-DA fi les are on the same disc as MP3
or WMA fi les, 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 fi les other than MP3/WMA fi les and
unnecessary folder on a disc.
≥
The name of MP3/WMA fi le should be added by
rules as shown in the following descriptions and
also comply with the rules of each fi le system.
≥
You may encounter trouble in playing MP3/WMA
fi les or displaying the information of MP3/WMA
fi les recorded with certain writing software or CD
recorders.
≥
The fi le extension “.mp3” or “.wma” should be
assigned to each fi le depending on the fi le format.
≥
This unit does not have the play list function.
≥
Although Multi-session recording is supported,
the use of Disc-at-Once is recommended.
Supported fi le systems:
ISO 9660 Level 1/Level 2, Apple Extension to ISO
9660, Joliet, Romeo
Note:
≥
Apple HFS, UDF 1.50, Mix CD, CD Extra are not
