MP3/WMA files
MP3 (MPEG Audio Layer 3) and WMA
D
(Windows Media Audio) are audio
compression 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, add
D
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.
The player can play only the first ses-
D
sion using multi−session compatible
CDs.
MP3 files are compatible with the ID3
D
Tag Ver. 1.0, Ver. 1.1, Ver. 2.2, and Ver.
2.3 formats. The unit cannot display
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
D
only when playing MP3/WMA files re-
corded at 32, 44.1 and 48 kHz. (The
system can play MP3 files with sam-
pling frequencies of 16, 22.05, and 24
kHz. However, the emphasis function
is not available for files recorded at
these frequencies.)
The sound quality of MP3/WMA files
D
generally improves with higher bit rate-
s. In order to achieve a reasonable lev-
el of sound quality, discs recorded with
a bit rate of at least 128 kbps are rec-
ommended.
Playable bit rates
MP3 files:
MPEG1 LAYER3—64 to 320 kbps
MPEG2 LSF LAYER3—64 to 160 kbps
WMA files:
Ver. 7, 8 CBR—48 to 192 kbps
Ver. 9 CBR—48 to 320 kbps
The MP3/WMA player does not play
D
back MP3/WMA files from discs re-
corder using packet write data transfer
(UDF format). Discs should be re-
corded using "pre−mastering" software
rather than packet−write software.
The m3u playlists are not compatible
D
with 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).
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 levels
D
deep can be played. However, the
start of playback may be delayed when
using discs containing numerous lev-
els of folders. For this reason, we rec-
ommend creating discs with no more
than two levels of folders.
It is possible to play up to 192 folders or
D
255 files on one disc.
