Notes on MP3
What is MP3 ?
MP3 (MPEG Audio Layer-3) is the compression format of digital
audio. It is developed by MPEG (Motion Picture Experts Group).
Using this compression format, you can record the contents of
about 10 music CDs on a single CD (This figure refers to data
recorded on a 650 MB CD-R or CD-RW at a fixed bit rate of 128
kbps and a sampling frequency of 44.1 kHz).
Note:
¡ MP3 encoding and CD writing software programs are not
supplied with this unit.
Points to remember when making MP3 files
¡ High bit rate and high sampling frequency are recommended
for high quality sound.
¡ Selecting VBR (Variable Bit Rate) is not recommended
because playing time is not displayed properly and sound
may be skipped.
¡ The playback sound quality differs depending on the encoding
circumstances. For details, refer to the instructions of your
own encoding software and writing software.
¡ It is recommended to set the bit rate to “128 kbps or more”
and “fixed”.

Caution
¡ Never assign the “.mp3” file name exten-
sion to a file that is not in the MP3 format.
This may not only produce noise from the
speaker damage, but also damage your
hearing.
¡ You are recommended to minimize the chances of making a
disc that contains both CD-DA files and MP3 files.
¡ If CD-DA files are on the same disc as MP3 files, the songs
may not play in the intended order, or some songs may not
play at all.
¡ Do not record files other than MP3 files and unnecessary fold-
er on a disc.
¡ The name of an MP3 file should be added by rules as shown
in the following descriptions and also comply with the rules of
each file system.
¡ The file extension “.mp3” should be assigned to each file
depending on the file format.
¡ You may encounter trouble in playing MP3 files or displaying
the information of MP3 files recorded with certain writing
software or CD recorders.
¡ This unit does not have a play list function.
¡ Although Multi-session recording is supported, the use of
Disc-at-Once is recommended.
