MP3 and WMA files
• MP3 is short for MPEG Audio Layer 3 and
refers to an audio compression technology
standard.
• WMA is short for Windows Media
TM
Audio
and refers to an audio compression tech-
nology that is developed by Microsoft
Corporation. WMA data can be encoded
by using Windows Media Player version 7
or later.
• With some applications used to encode
WMA files, this unit may not operate cor-
rectly.
• With some applications used to encode
WMA files, album names and other text
information may not be correctly dis-
played.
• This unit allows playback of MP3/WMA
files on CD-ROM, CD-R and CD-RW discs.
Disc recordings compatible with level 1
and level 2 of ISO9660 and with the
Romeo and Joliet file system can be
played back.
• It is possible to play back multi-session
compatible recorded discs.
• MP3/WMA files are not compatible with
packet write data transfer.
• The maximum number of characters which
can be displayed for a file name, including
the extension (.mp3, .wma), is 64 , from
the first character.
• The maximum number of characters which
can be displayed for a folder name is 64 .
• In case of files recorded according to the
Romeo file system, only the first 64 char-
acters can be displayed.
• The folder selection sequence for playback
and other operations becomes the writing
sequence used by the writing software.
For this reason, the expected sequence at
the time of playback may not coincide with
the actual playback sequence. However,
there also is some writing software which
permits setting of the playback order.
MP3 additional infor-
mation
• Files are compatible with the ID3 Tag Ver.
1.0, 1.1, 2.2, 2.3 and 2.4 formats for dis-
play of album (disc title), track (track title),
artist (track artist) and comments. Ver. 2.x
of ID3 Tag is given priority when both Ver.
1.x and Ver. 2.x exist.
• The emphasis function is valid only when
MP3 files of 32, 44.1 and 48 kHz frequen-
cies are played back. (16, 22.05, 24, 32,
44.1, 48 kHz sampling frequencies can be
played back.)
• There is no m3u play list compatibility.
• There is no compatibility with the MP3i
(MP3 interactive) or mp3 PRO formats.
• The sound quality of MP3 files generally
becomes better with an increased bit
rates. This unit can play recordings with bit
rates from 8 kbps to 320 kbps, but in order
to be able to enjoy sound of a certain quali-
ty, we recommend using only discs
recorded with a bit rate of at least 128
kbps.
IMPORTANT
•
When naming an MP3/WMA
file, add the corresponding
filename extension (.mp3,
.wma).
•
This unit plays back files
with the filename extension
(.mp3, .wma) as an MP3/
WMA file. To prevent noise
and malfunctions, do not
use these extensions for
files other than MP3/WMA
files.
