175 MP3/WMA files
MP3 (MPEG Audio Layer 3) and WMA
(Windows Media Audio) are audio com-
pression 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 compat-
ible 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 play-
back errors, use the appropriate file ex-
tensions.
The player can play only the first session
using multi−session compatible CDs.
MP3 files are compatible with the ID3 Tag
Ver. 1.0, Ver. 1.1, Ver. 2.2, and Ver. 2.3 for-
mats. The unit cannot display disc title,
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 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-
erally improves with higher bit rates. In or-
der 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 recorder using
packet write data transfer (UDF format).
Discs should be recorded using “pre−
mastering” software rather than packet−
write software.
The m3u playlists are not compatible with
the audio player.
MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
The MP3 player is compatible with VBR
(Variable Bit Rate).
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.
MP3/WMA files in folders up to 8 levels
deep can be played. However, the start of
playback may be delayed when using
discs containing numerous levels of fol-
ders. For this reason, we recommend
creating discs with no more than two lev-
els of folders.
It is possible to play up to 192 folders or
255 files on one disc.

179 TERMS
Packet write—
This is a general term that describes the pro-
cess of writing data on−demand to CD−R,
etc., in the same way that data is written to
floppy or hard discs.
ID3 Tag—
This is a method of embedding track−related
information in an MP3 file. This embedded in-
formation can include the track title, the art-
ist’s name, the album title, the music genre,
the year of production, comments and other
data. The contents can be freely edited using
software with ID3 tag editing functions. Al-
though the tags are restricted to the number
of characters, the information can be viewed
when the track is played back.
WMA Tag—
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.ISO 9660 format—
This is the international standard for the for-
matting of CD−ROM folders and files. For the
ISO 9660 format, there are two levels of regu-
lations.
Level 1:
The file name is in 8.3 format (8 character file
names, with a 3 character file extension. File
names must be composed of one−byte capi-
tal letters and numbers. The “_” symbol may
also be included.)
Level 2:
The file name can have up to 31 characters
(including the separation mark “.” and file ex-
tension). Each folder must contain fewer than
8 hierarchies.m3u—
Playlists created using “WINAMP” software
have a playlist file extension (.m3u).
MP3—
MP3 is an audio compression standard deter-
mined by a working group (MPEG) of the ISO
(International Standard Organization). MP3
compresses audio data to about 1/10 the size
of that on conventional discs.
WMA—
WMA (Windows Media Audio) is an audio
compression format developed by Microsoft.
It compresses files into a size smaller than
that of MP3 files. The decoding formats for
WMA files are Ver. 7, 8, and 9.
