MP3 and WMA File Playback
MP3 (MPEG 1 Audio Layer-3) or WMA
(Windows media audio) is a standard
technology and format for compressing
audio data. This allows a more efficient
use of the media.
You can play MP3 files recorded on
CD-ROM, CD-R and CD-RW formats. The
disc must be in the ISO 9660 level 1 or level
2 format, or Joliet or Romeo in the
expansion format. You can also use a disc
recorded in multi session.
ISO 9660 Format
This is 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 eight characters in
the name, no more than three characters
in the extension MP3 and WMA) and in
capital letters.
Folder names can be no longer than eight
characters. There can be no more than
eight folder levels (trees). Level 2
specifications allow file names up to 31
characters long.
Each folder can have up to eight trees.
For Joliet or Romeo in the expansion
format, consider these restrictions when
configuring your CD writing software.
Multi Session
This recording method enables adding of
data using the track-at-once method.
Conventional CDs begin at a CD control
area called the lead-in and end at an area
called lead-out. A multi session CD is a CD
having multiple sessions, with each
segment from lead-in to lead-out regarded
as a single session.

Audio System
CD-Extra: The format that records audio
(audio CD data) as tracks on session 1, and
records data as tracks on session 2.
Mixed CD: In this format, data records as
track 1 and audio (audio CD data) records
as track 2.
File Formats
With formats other than ISO 9660 level 1
and level 2, folder names or file names may
not display correctly.
When naming, be sure to add the file
extension MP3 or WMA to the file name.
If you put the extension MP3 or WMA to a
file other than MP3 or WMA, the unit
cannot recognize the file correctly and
generates random noise that could
damage your speakers.
The following discs take a longer time to
start playback.
A disc recorded with complicated tree
structure.
A disc recorded in multi session.
A non-finalized disc, where you can add
more data.
Playing a Multi Session Disc
When the first track of the first session is
audio CD data only, the audio CD data of
the first session plays. Non-audio CD data,
MP3 or WMA file information (such as
track number and time) displays with no
sound.
When the first track of the first session is
not audio CD data:
If an MP3 or WMA file is on the disc, the
system skips these file and other data.
Audio CD data is not recognized.
If no MP3 or WMA file is in the disc,
nothing plays. Audio CD data is not
recognized.
