Notes on playing MP3/WMA
This unit can play MP3(MPEG1, 2, 2.5 Audio Layer 3)/WMA. Note,
however, that the MP3/WMA recording media and formats
acceptable are limited. When writing MP3/WMA, pay attention to
the following restrictions.
Acceptable media
The MP3/WMA recording media acceptable to this unit are CD-ROM,
CD-R, and CD-RW.
When using CD-RW, do full format not quick format to prevent
malfunction.
Acceptable medium formats
The following formats are available for the media used in this unit. The
maximum number of characters used for file name including the
delimiter (".") and three-character extension are indicated in
parentheses.
• ISO 9660 Level 1 (12 characters)
• ISO 9660 Level 2 (31 characters)
• Joliet (64 characters)
• Romeo (128 characters)
Up to 200 characters can be displayed in the long file name format.
For a list of available characters, see the instruction manual of the
writing software and the section Entering file and folder names below.
The media reproducible on this unit has the following limitations:
• Maximum number of directory levels: 8
• Maximum number of files per folder: 255
• Maximum number of characters for folder name: 64
• Maximum number of folders: 50
MP3/WMA written in the formats other than the above may not be
successfully played and their file names or folder names are not
properly displayed.
Settings for your MP3/WMA encoder and CD writer
Do the following setting when compressing audio data in MP3/WMA
data with the MP3/WMA encoder.
• Transfer bit rate MP3: 8 —320 kbps
WMA: 48 —192 kbps
• Sampling frequency
MP3: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 kHz
WMA: 32, 44.1, 48 kHz
Play mode may not be possible when portions of the functions of
Windows Media Player 9 or higher are used.
When you use your CD writer to record MP3/WMA up to the
maximum disc capacity, disable additional writing. For recording on an
empty disc up to the maximum capacity at once, check Disc at Once.
Entering ID3 tag and Contents
Description
The Displayable ID3 tag is ID3 version
1.x.
For the character code, refer to the List
of Codes.
Entering file and folder names
The code list characters are the only file
names and folder names that can be
entered and displayed.
If you use any other character for entry,
the file and folder names are not displayed correctly. They may neither
be displayed correctly depending on the CD writer used.
The unit recognizes and plays only those MP3/WMA which have the
MP3/WMA extension (.MP3/.WMA).
A file with a name entered with characters not on the code list may not
play correctly.
Writing files into a medium
When a medium containing MP3/WMA data is loaded, the unit checks
all the data on the medium. If the medium contains a lot of folders or
non-MP3/WMA files, therefore, it takes a long time until the unit starts
playing MP3/WMA.
In addition, it may take time for the unit to move to the next MP3/WMA
file or a File Search or Folder Search may not be performed smoothly.
Loading such a medium may produce loud noise to damage the speakers.
• Do no attempt to play a medium containing a non-MP3/WMA
file
with the MP3/WMA extension.
The unit mistakes non-MP3/WMA
file
s for MP3/WMA data as long as
they have the MP3/WMA extension.
• Do not attempt to play a medium containing non MP3/WMA.
