MP3, WMA and AAC 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 for-
mat.
AAC is short for Advanced Audio Coding and refers to an audio compression
technology standard used with MPEG2 and MPEG4.
MP3, WMA and AAC file and media/fo rmats compatibility are limited.

not finalized. Playback may not be possible or the audio may jump if the
disc is scratched or marked with fingerprints.

• 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)
UDF (2.01 or lower)
MP3, WMA and AAC 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/AAC and played are
those with the extension .mp3, .wma or .m4a.
● Discs containing multi-session recordings
As the audio system is compatible with multi session discs, it is possible to
play discs that contain MP3, WMA and AAC files. However, only the first
session can be played.

ID3, WMA and AAC 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.
AAC tags can be added to AAC files, making it possible to record the track
title and artist name in the same way as with ID3 tags.
● MP3, WMA and AAC playback
When a disc containing MP3, WMA or AAC files is inserted, all files on the
disc are first checked. Once the file check is finished, the first MP3, WMA or
AAC file is played. To make the file check finish more quickly, we recom-
mend you do not write any files to the disc other than MP3, WMA or AAC
files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3, WMA or AAC format
data cannot be played.
● Extensions
If the file extensions .mp3, .wma and .m4a are used for files other than
MP3, WMA and AAC files, they may be mistakenly recognized and played
as MP3, WMA and AAC files. This may result in large amounts of interfer-
ence 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, WMA and AAC 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, WMA or AA C 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.
