MP3 files are compatible with the ID3 Tag
D
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 for-
mats.
WMA files can contain a WMA tag that is
D
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 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 gen-
D
erally 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 recom-
mended.
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 back
D
MP3/WMA files from discs recorded using
packet write data transfer (UDF format).
Discs should be recorded using "pre-
mastering" software rather than packet-
write software.
M3u playlists are not compatible with the
D
audio player.
MP3i (MP3 interactive) and MP3PRO for-
D
mats are not compatible with the audio
player.
The MP3 player is compatible with VBR
D
(Variable Bit Rate).
When playing back files recorded as VBR
D
(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
D
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 levels of fold-
ers. For this reason, we recommend
creating discs with no more than two le-
vels of folders.
It is possible to play up to 192 folders or
D
255 files on one disc.
