MP3/WMA FILES
• The sound quality of MP3/WMA files is generally better
at higher bit rates. In order to achieve an acceptable
level of sound quality, it is recommended to use
discs recorded at a bit rate of at least 128 kbps.
• MP3 (MPEG Audio Layer 3) and WMA (Windows
Media Audio) are audio compression standards.
• The MP3/WMA player enables playback of MP3 and
WMA files on CD-ROM, CD-R and CD-RW discs.
Playable bit rates
MP3 files:
MPEG1 LAYER3 - 64 to 320 kbps
MPEG2 LSF LAYER3 - 64 to 160 kbps
WMA files:
The drive can play disc recordings compatible with
ISO 9660 levels 1 and 2 and the Romeo and Joliet
file systems.
Ver7, 8 CBR - 48 to 192 kbps
Ver9 CBR - 48 to 320 kbps
• When naming an MP3 or WMA file, specify the
appropriate file name extension (.mp3 or .wma).
• The MP3/WMA player does not play MP3/WMA files
from discs recorded using packet data transfer
recording (UDF format).
• The MP3/WMA player plays files with a .mp3 or .wma
file name extension as MP3 or WMA files.
Discs should be recorded using "pre-
mastering" software rather than packet
burning software.
To avoid noise and malfunctions, use the
appropriate terminal.
• M3u playlists are not compatible with this audio player.
• It is also possible to play multi-session compatible
discs.
• MP3i (MP3 interactive) or MP3PRO formats are not
• MP3 files are compatible with ID3 Tags format Ver.

compatible with this audio player.
2.3. In other formats, the unit cannot
display disc name, track name and artist
name.
• The MP3 player is compatible with VBR (Va-riable Bit
Rate).
• WMA files can contain WMA tags, which are used in
the same way as ID3 tags. WMA tags contain
information such as track title, artist name.
• When playing files recorded as VBR (Variable Bit Rate)
files, the playback time will not be displayed correctly
if you use the fast forward or fast reverse operation.
• The highlight function is effective only when MP3/WMA
files sampled at 32, 44.1 and 48 kHz are played. (The
system can play MP3 files with sampling rates of 16,
22.05 and 24 kHz. However, the highlight function is
not available for files recorded at these frequencies.)
• Folders that do not contain MP3/WMA files cannot be
checked.
• MP3/WMA files up to 8 folder levels can be played.
However, discs with more folder levels will
experience a delay in starting playback. For this
reason, we recommend creating discs that have no
more than 2 levels of folders.
• Up to 192 folders or 255 files can be played on one
disc.
