MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio com-
pression standards.
 This system can play MP3/WMA/AAC files
on CD-R/CD-RW discs and USB memory.
 This system can play disc recordings com-
patible with ISO 9660 level 1 and level 2
and with the Romeo and Joliet file system
and UDF (2.01 or lower).
 When naming an MP3/WMA/AAC file, add
an appropriate file extension (.mp3/.wma/
.m4a).
 This system plays back files with .mp3/
.wma/.m4a file extensions as MP3/WMA/
AAC files respectively. To prevent noise
and playback errors, use the appropriate
file extension.
 This system can play only the first ses-
sion/border when using multi-session/bor-
der compatible discs.
 MP3 files are compatible with the ID3 Tag
Ver. 1.0, Ver. 1.1, Ver. 2.2 and Ver. 2.3 for-
mats. This system cannot display disc
title, track title and artist name in other for-
mats.
 WMA/AAC files can contain a WMA/AAC
tag that is used in the same way as an ID3
tag. WMA/AAC tags carry information
such as track title and artist name.
 The emphasis function is available only
when playing MP3 files.
 This system can play back AAC files
encoded by iTunes.

The sound quality of MP3/WMA files gen-
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.
 m3u playlists are not compatible with the
audio player.
 MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
 The player is compatible with VBR (Vari-
able Bit Rate).
 When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displayed if the fast for-
ward or reverse operations are used.
 It is not possible to check folders that do
not include MP3/WMA/AAC files.
 MP3/WMA/AAC 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 recommend
creating discs with no more than 2 levels
of folders. 
The play order of the compact disc with
the structure shown above is as follows:
 The order changes depending on the per-
sonal computer and MP3/WMA/AAC
encoding software you use.

This is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is writ-
ten to floppy or hard discs.
 This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track number, track title, the artist’s name,
the album title, the music genre, the year
of production, comments, cover art and
other data. The contents can be freely
edited using software with ID3 tag editing
functions. Although the tags are restricted
to a number of characters, the information
can be viewed when the track is played
back.
 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
and artist name.
 This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are 2 lev-
els of regulations.
 Level 1: The file name is in 8.3 format (8
character file names, with a 3 character
file extension. File names must be com-
posed of one-byte capital letters and num-
bers. The “_” symbol may also be
included.)
 Level 2: The file name can have up to 31
characters (including the separation mark
“.” and file extension). Each folder must
contain fewer than 8 hierarchies. 
Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
 MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
 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 decod-
ing formats for WMA files are Ver. 7, 8 and
9.
