(Variable Bit Rate (VBR) compatible)
. MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC (Advanced Audio Coding) are audio compression standards.
. This system can play MP3/WMA/AAC
files on CD-R, CD-RW discs, USB memory, and Bluetooth device.
. This system can play disc recordings
compatible with ISO 9660 level 1 and level
2 and with the Romeo and Joliet file
system.
. 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
session when 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
formats. This system cannot display disc
title, track title and artist name in other
formats.
. 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/WMA files recorded at
32, 44.1 and 48 kHz.
. This system can play back AAC files
encoded by iTunes.
. The sound quality of MP3/WMA files
generally 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.
. The MP3/WMA player does not play
back MP3/WMA files from discs recorded
using packet write data transfer (UDF
format). Discs should be recorded using
“pre-mastering” software rather than
“packet write” software.

. M3u playlists are not compatible with
the audio device.
. MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the audio
device.
. The 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 the fast
forward 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
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.
