3-2. Using the audio system
●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 you
do not write in any files other than MP3 or WMA files or create any unnec-
essary folders.
If the discs contain a mixture of music data and MP3 or WMA format data,
only music data can 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 file 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.
