What is MP3/WMA?
MP3 (MPEG1/2 Audio Layer-III) and WMA
(Windows Media
TM
Audio) are the com-
pression formats of digital audio. The
former is developed by MPEG (Motion Pic-
ture 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).
Points to remember when making MP3/
WMA files
Common
 High bit rate and high sampling fre-
quency are recommended for high qual-
ity 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 circum-
stances. 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 play
back.
NOTE:
Never assign the “.mp3”, or “.wma” file
name extension to a file that is not in the
MP3/WMA format. This may not only pro-
duce 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 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 unnecessary folder on a disc.
 The name of an MP3/WMA file should
be added by rules as shown in the fol-
lowing descriptions and also comply with
the rules of each file system.
 The file extension “.mp3” or “.wma”
should be assigned to each file depend-
ing on the file format. You may encounter trouble in playing
MP3/WMA files or displaying the infor-
mation of MP3/WMA files recorded with
certain writing software or CD recorders.
 This unit does not have a play list func-
tion.
 Although Multi-session recording is sup-
ported, the use of Disc-at-Once is rec-
ommended.
