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) includ-
ing 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.
