MP3/WMA files
MP3 (MPEG Audio Layer 3) and
WMA (Windows Media Audio) are
audio compression standards.
The MP3/WMA player can play MP3
and WMA files on CD-R and CD-RW
discs.
The unit can play disc recordings
compatible with ISO 9660 level 1
and level 2 and with the Romeo and
Joliet file system.
The USB player can play MP3 and
WMA files on USB memory device.
When naming an MP3 or WMA file,
add the appropriate file extension
(.mp3 or .wma).
The MP3/WMA player and USB
player play back files with .mp3
or .wma file extensions as MP3 or
WMA files. To prevent noise and
playback errors, use the appropriate
file extensions.
The player can play only the first
session using multi-session com-
patible CDs.
MP3 files are compatible with the
ID3 Tag Ver. 1.0, Ver. 1.1, Ver. 2.2,
Ver. 2.3 and Ver. 2.4 formats. The
unit cannot display disc title, track ti-
tle, artist name, and so on in other
formats.
WMA files can contain a WMA tag
that is used in the same way as an
ID3 tag. WMA tags carry informa-
tion such as track title, artist name.
The emphasis function is available
only when playing MP3/WMA files
recorded at 22.05, 32, 44.1 and 48
kHz. (The system can play MP3
files with sampling frequencies of 8,
11.025, 12, 16 and 24 kHz. How-
ever, the emphasis function is not
available for files recorded at these
frequencies.)
The sound quality of MP3/WMA files
generally improves with higher bit
rates. In order to achieve a rea-
sonable level of sound quality, discs
and USB memory device recorded
with a bit rate of at least 128 kbps
are recommended.
Playable bit rates
MP3 files:
MPEG1 LAYER3—32 to 320 kbps
MPEG2 LAYER3—8 to 160 kbps
MPEG2.5 LAYER3—8 to 160 kbps
WMA files:
Ver. 7, 8, 9—32 to 320 kbps
The MP3/WMA player does not play
back MP3/WMA files from discs re-
corder 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 formats 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 dis-
played if fast-forward or reverse op-
erations 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. How-
ever, the start of playback may be
delayed when using discs containing
numerous levels of folders. For this
reason, we recommend creating
discs and USB memory device with
no more than two levels of folders.
It is possible to play up to 255 fold-
ers or 999 files on one disc and USB
memory device.
