About MP3 files

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.

Notes on discs/"Memory Stick"
You can play MP3 files recorded on CD-ROMs,
CD-Rs, and CD-RWs.
The disc must be in the ISO 9660* level 1 or
level 2 format, or Joliet in the expansion
format.
* ISO 9660 Format
The most common international standard
for the logical format of files and folders on
a CD-ROM.
There are several specification levels. In
level 1, file names must be in the 8.3 format
(no more than 8 characters in the name, no
more than 3 characters in the extension
".MP3") and in capital letters. Folder names
can be no longer than 8 characters. There can
be no more than 8 nested folder levels. Level
2 specifications allow file names up to 31
characters long.
Each folder can have up to 8 trees.
For Joliet in the expansion format, make sure
of the contents of the writing software, etc.
Notes
• With formats other than ISO 9660 level 1 and
level 2, folder names or file names may not be
displayed correctly.
• 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 MP3, the player cannot recognize the file
properly and will generate random noise that
could damage your speakers.
• The following discs/"Memory Stick" take a
longer time to start playback.
— a disc/"Memory Stick" recorded with
complicated tree structure.
— a disc to which data can be added.
• A high-bit rate MP3 file such as 320 kbps may not
play back properly.
The playback order of the MP3 files
The playback order of the folders and files is as
follows:
32 k, 44.1 k, 48 k
128 k
Tip
To specify a desired playback order, before the
folder or file name, input the order by number
(e.g., "01," "02"), then record contents onto a disc
(The order differs depending on the writing
software).
