MP3 and WMA files
MP3 (MPEG Audio LAYER 3) 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 that can be used and to
the media/formats on which the files are recorded.

Compatible media
Media that can be used for MP3 and WMA playback are CD-Rs and CD-
RW s .
Playback in some instances may not be possible if the CD-R or CD-RW is
not finalized. Playback may not be possible or the audio may jump if the
disc is scratched or marked with fingerprints.
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 (including the root)
• 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.
Discs containing multi-session recordings
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 ses-
sion can be played.

ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track
title, 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
you do not write in any files other than MP3 or WMA files or create any
unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data
cannot be played.
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 at least 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.
• Microsoft, Windows, and Windows Media are the registered trade-
marks of Microsoft Corporation in the U.S.A. and other countries.
