MP3/WMA FILES
MP3 (MPEG Audio Layer 3) and WMA
(Windows Media Audio) are audio com-
pression standards.
The MP3/WMA player can play MP3
and WMA files on CD−ROM, CD −R and
CD− RW discs.
The unit can play disc recordings com-
patible with ISO 9660 level 1 and level
2 and with the Romeo and Joliet file
system.
When naming an MP3 or WMA file,
add the appropriate file extension (.mp3
or .wma).
The MP3/WMA player plays back files
with .mp3 or .wma file extensions as
MP3 or WMA files. To prevent noise
and playback errors, use the appropri-
ate file extensions.
Multi −session compatible CDs can also
be played.
MP3 files are compatible with the ID3
Tag Ver.1.0, Ver.1.1 and Ver.2.2, and
Ver. 2.3 formats. The unit cannot dis-
play disc title, track title and artist
name in other formats.
WMA files can contain a WMA tag that
is used in the same way as an ID3
tag. WMA tags carry information such
as track title, artist name.
The emphasis function is available only
when playing MP3/WMA files recorded
at 32, 44.1 and 48 kHz. (The system
can play MP3 files with sampling fre-
quencies of 16, 22.05, and 24 kHz.
However, the emphasis function is not
available for files recorded at these fre-
quencies.)
The sound quality of MP3/WMA files
generally improves with higher bit
rates. In order to achieve a reasonable
level of sound quality, discs recorded
with a bit rate of at least 128 kbps are
recommended.
Playable bit rates
MP3 files:
MPEG1 LAYER3—64 to 320 kbps
MPEG2 LSF LAYER3—64 to 160 kbps
WMA files:
Ver7, 8 CBR—48 to 192 kbps
Ver9 CBR—48 to 320 kbps
The MP3/WMA player does not play
back MP3/WMA files from discs record-
er using packet write data transfer
(UDF format). Discs should be re-
corded using “pre −mastering” software
rather than packet −write software.
M3u playlists are not compatible with
the audio player.
MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the au-
dio player.
The MP3 player is compatible with
VBR (Variable Bit Rate).
When playing back files recorded as
VBR (Variable Bit Rate) files, the play
time will not be correctly displayed if
fast −forward or reverse operations are
used.
It is not possible to check folders that
do not include MP3/WMA files.
MP3/WMA files in folders up to 8 lev-
els deep can be played. However, the
start of playback may be delayed when
using discs containing numerous levels
of folders. For this reason, we recom-
mend creating discs with no more than
two levels of folders.
It is possible to play up to 192 folders
or 255 files on one disc.

MP3/WMA player (front audio system)
The play order of the compact disc
with the structure shown on the left is
as follows:
MP3 player (rear seat entertainment sys-
tem)
001.mp3 002.mp3 . . . 006.mp3
MP3/WMA player (front audio system)
001.mp3 002.wma . . . 006.mp3
MP3 player (rear seat entertainment
system)—It is possible to play up to
253 folders on one disc.
MP3/WMA player (front audio sys-
tem)—It is possible to play up to 192
folders or 255 files on one disc.
The order changes depending on the
PC and MP3/WMA encoding software
you use. CDR and CDRW discs
CD−
R/CD− RW discs that have not been
subject to the “finalizing process” (a
process that allows discs to be played
on a conventional CD player) cannot
be played.
It may not be possible to play CD −
R/CD− RW discs recorded on a music
CD recorder or a personal computer
because of disc characteristics,
scratches or dirt on the disc, or dirt,
condensation, etc. on the lens of the
unit.
It may not be possible to play discs
recorded on a personal computer de-
pending on the application settings and
the environment. Record with the cor-
rect format. (For details, contact the
appropriate application manufacturers of
the applications.)
CD− R/CD− RW discs may be damaged
by direct exposure to sunlight, high
temperatures or other storage condi-
tions. The unit may be unable to play
some damaged di scs.
If you insert a CD −RW disc into the
MP3/WMA player, playback will begin
more slowly than with a conventional
CD or CD −R disc.

Recordings on CD−R/CD− RW cannot
be played using the DDCD (Double
Density CD) system. TERMS
Packet write—
This is a general term that describes the
process of writing data on
−demand to
CD− R, etc., in the same way that data is
written to floppy or hard discs.
ID3 Tag—
This is a method of embedding track −re-
lated information in an MP3 file. This em-
bedded information can include the track
title, the artist’s name, the album title, the
music genre, the year of production, com-
ments and other data. The contents can
be freely edited using software with ID3
tag editing functions. Although the tags
are restricted to the number of characters,
the information can be viewed when the
track is played back.
WMA Tag—
WMA files can contain a WMA tag that is
used in the same way as an ID3 tag.
WMA tags carry information such as track
title, artist name. ISO 9660 format—
This is the international standard for the
formatting of CD
−ROM folders and files.
For the ISO 9660 format, there are two
levels of regulations.
Level 1:
The file name is in 8.3 format (8 charac-
ter file names, with a 3 character file ex-
tension. File names must be composed of
one− byte capital letters and numbers. The
“_” symbol may also be included.)
Level 2:
The file name can have up to 31 charac-
ters (including the separation mark “.” and
file extension). Each folder must contain
fewer than 8 hierarchies.
m3u—
Playlists created using “WINAMP” software
have a playlist file extension (.m3u).
MP3—
MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on convention-
al discs.
