MP3/WMA FILES
MP3 (MPEG Audio Layer 3) and WMA
(Windows Media
Audio) are audio
compression 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.
The MP3/WMA player can play only
the first session using multi
−
session
compatible CDs.
MP3 player—MP3 files are compatible
with the ID3 Tag Ver. 1.0, Ver. 1.1, Ver.
2.2, and Ver. 2.3 formats. The unit can-
not display disc title, track title and art-
ist name in other formats.
USB memory—MP3 files are compat-
ible with the ID3 Tag Ver. 1.0, Ver. 1.1,
Ver. 2.2, Ver. 2.3 and Ver. 2.4 formats.
The unit cannot display 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 re-
corded at 32, 44.1 and 48 kHz.
