■CORRESPONDING BIT RATES
(Variable Bit Rate (VBR) compatible)
zMP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio com-
pression standards.
z This system can play MP3/WMA/AAC
files on CD-R, CD-RW, DVD-R, DVD-RW
discs and USB memory.
z This system can play disc recordings com-
patible with ISO 9660 level 1 and level 2
and with the Romeo and Joliet file system.
z When naming an MP3/WMA/AAC file,
add an appropriate file extension (.mp3/
.wma/.m4a).
z 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.
z This system can play only the first session
when using multi-session compatible CDs.
z MP3 files are compatible with the ID3 Tag
Ve r. 1 . 0 , Ve r. 1 .1 , Ve r. 2 . 2 a n d Ve r. 2 . 3 f o r -
mats. This system cannot display disc title,
track title and artist name in other formats.
z WMA/AAC files can contain a WMA/
AAC tag that is used in the same way as an
ID3 tag. WMA/AAC tags carry informa-
tion such as track title and artist name.
z The emphasis function is available only
when playing MP3/WMA files recorded at
32, 44.1 and 48 kHz.
z This system can play back AAC files
encoded by iTunes.

zThe 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 recommended.
z M3u playlists are not compatible with the
audio player.
z MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the audio
player.
z The player is compatible with VBR (Vari-
able Bit Rate).
z 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.
z It is not possible to check folders that do not
include MP3/WMA/AAC files.
z MP3/WMA/AAC 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
folders. For this reason, we recommend
creating discs with no more than 2 levels of
folders. z
The play order of the compact disc with the
structure shown above is as follows:
z The order changes depending on the per-
sonal computer and MP3/WMA/AAC
encoding software you use.

zThis is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is written
to floppy or hard discs.
z 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 func-
tions. Although the tags are restricted to a
number of characters, the information can
be viewed when the track is played back.
z 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. z
This is the international standard for the for-
matting of CD-ROM folders and files. For
the ISO 9660 format, there are 2 levels of
regulations.
z 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 capital letters and numbers. The
“_” symbol may also be included.)
z 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.
z 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.

zWMA (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.
z AAC is short for Advanced Audio Coding
and refers to an audio compression tech-
nology standard used with MPEG2 and
MPEG4.
