MP3/WMA FILES
MP3 (MPEG Audio Layer 3) and WMA
D
(Windows Media Audio) are audio com-
pression standards.
The MP3/WMA player can play MP3
D
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,
D
add the appropriate file extension (.mp3
or .wma).
The MP3/WMA player plays back files
D
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
D
be played.
MP3 files are compatible with the ID3
D
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
D
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
D
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
D
generally improves with higher
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
D
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
D
the audio player.
MP3i (MP3 interactive) and MP3PRO
D
formats are not compatible with the au-
dio player.
The MP3 player is compatible with
D
VBR (Variable Bit Rate).
bit
When playing back files recorded as
D
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
D
do not include MP3/WMA files.
MP3/WMA files in folders up to 8 lev-
D
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
D
or 255 files on one disc.
