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
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:
Ver. 7, 8 CBR—48 to 192 kbps
Ver. 9 CBR—48 to 320 kbps

The MP3/WMA player does not play
back MP3/WMA files from discs record-

corded using "per−mastering" software
rather than packet−write software.

the audio player.

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.
D
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.
D
It is possible to play up to 192 folders
or 255 files on one disc.
