■MP3 and WMA files
MP3 (MPEG Audio LAYER3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size by using
MP3 compression.
WMA (Windows Media
® Audio) is a Microsoft® audio compression format.
This format compresses audio data to a size smaller than that of the MP3
format.
There is a limit to the MP3 and WMA file standards and to the media/formats
recorded by them that can be used.

Compatible disc formats
The following disc formats can be used.
• Disc formats: CD-ROM Mode 1 and Mode 2
CD-ROM XA Mode 2, Form 1 and Form 2
• File formats: ISO9660 Level 1, Level 2, (Romeo, Joliet) MP3 and WMA files written in any format other than those listed above
may not play correctly, and their file names and folder names may not
be displayed correctly.
Items related to standards and limitations are as follows.
• Maximum directory hierarchy: 8 levels
• Maximum length of folder names/file names: 32 characters
• Maximum number of folders: 192 (including the root)
• Maximum number of files per disc: 255
● File names
The only files that can be recognized as MP3/WMA and played are those
with the extension .mp3 or .wma.
● Multi-sessions
As the audio system is compatible with multi-sessions, it is possible to play
discs that contain MP3 and WMA files. However, only the first session can
be played.
● ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track
title and artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags.
(The number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the
track title and artist name in the same way as with ID3 tags.
● MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc
are first checked. Once the file check is finished, the first MP3 or WMA\
file
is played. To make the file check finish more quickly, we recommend that
you do not save any files other than MP3 or WMA files or create any
unnecessary folders.
If the discs contain a mixture of music data and MP3 or WMA format data,
only music data can be played.

300 3-2. Using the audio system
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and
WMA files, they will be mistakenly recognized and played as MP3 and
WMA files. This may result in large amounts of interference and damage
to the speakers.
● Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit
rate of 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances, depending on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depending on the status of the
encoding and the file format, poor sound quality or noise at the start of
playback may result. In some cases, playback may not be possible at
all.
• When files other than MP3 or WMA files are recorded on a disc, it may take more time to recognize the disc and in some cases, playback may
not be possible at all.

marks of Microsoft Corporation in the U.S. and other countries.
