About "MP3"
What is the MP3
MP3 (MPEG 1 Audio Layer-3) is a standard technology
and format for compressing a sound sequence. The file
is compressed to about 1/10 of its original size.
Sounds outside the range of human hearing are
compressed while the sounds we can hear are not
compressed.
Playable "MP3" files on the player
You can only play MP3 files recorded by following
requirements.
Usable media
CD-Rs and CD-RWs
Usable disc format
You can use ISO 9660 Level 1, Level 2 and Joliet
extension format discs. In some cases, MP3 files that
are recorded in a format other than these formats may
not play normally or the file and folder names may not
be displayed correctly.
The major specifications of the usable disc format are
as follows:
• Maximum directory steps: 8
• Usable characters for a file/folder name: A - Z, a - z,
0 - 9 and _ (underscore)
• Maximum number of characters for a file name: 16 (8)
including quotation marks and a 3-character
extension code
Notes
• When naming, be sure to add the file extension "mp3"
to the file name.
• If you put the extension "mp3" to a file other than an
MP3 file, the player cannot recognize the file properly
and will generate random noise that could damage
your speaker.
• The file name does not correspond to the ID tag.
The usable number of folders/files
• Maximum number of folders and files: 512 (in total)
Settings for compression software and writing
software
• To compress a source for an MP3 file, we
recommend setting the transfer bit rate of the
compression software to "44.1 kHz", "128 kbps" and
"Constant Bit Rate".
• To record up to the maximum capacity, set to the
"halting of writing".
• To record at one time up to the maximum capacity on
media that has nothing recorded it, set to "Disc at
Once".
Notes for saving files on the media
When the disc is inserted, the player reads all the files
on that disc. If there are many folders or non-MP3 files
on the disc, it may take a long time for play to begin or
for the next MP3 file to start play.
Do not save unnecessary folders or files other than
MP3 ones in the disc to be used for MP3 listening.
We recommend that you do not save other types of files
or unnecessary folders on a disc that has MP3 files.
About "ID3 tag"
ID3 tag is a format for adding certain information (track
title, artist name and album title, etc.) to MP3 files.
This player conforms to Version 1.1 of the ID3 tag
information, "track title", "artist name" and "album title"
can be displayed.
Note
If you use a version other than 1.1, ID3 tag information
will not be displayed correctly.
