What is MP3?
MP3 is an audio compression method and clas-
sified into audio layer 3 of MPEG standards. This
audio compression method has penetrated into
PC users and become a standard format. This
MP3 features the original audio data compres-
sion to about 12 percent of its initial size with a
high quality sound. This means that about 10
music CDs can be recorded on a CD-R disc or
CD-RW disc to allow a long listening time with-
out having to change CDs.

MP3 playing order
When selected for play folder up down functions,
files and folders are accessed in the order in which
they were written by the CD-ROM writer.
Because of this, the order in which they are
expected to be played may not match the order in
which they are actually played. You may be able
to set the order in which MP3 are to be played by
writing them onto a medium such as a CD-R with
their file names beginning with play sequence
numbers such as "01" to "99", depending on your
CD writer.
For example, a medium with the following folder/
file hierarchy is shown below.
