(Variable Bit Rate (VBR) compatible)
. MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC (Ad-
vanced Audio Coding) are audio compres-
sion standards.
. This system can play MP3/WMA/AAC
files on CD-R, CD-RW discs, USB mem-
ory, 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.
Bit rate (kbps)
. This system can play only the first
session when using multi-session compa-
32 - 320
tible 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
CBR 48 - 192
title, track title and artist name in other
CBR 32 - 192
formats.
. WMA/AAC files can contain a WMA/
16 - 320
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.
. 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 recom-
mended.
. 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 pack-
etwrite software.
