CD/MP3 Player (continued)
This player allows you to play MP3 files recorded on CD-ROMs, CD-Rs
(Recordable) and CD-RWs (Rewritable).
¡It is recommended that you set the bit rate to “128 kbps or more” and “Fixed”.
¡Bit rate 8 kbps of MPEG-2 and sampling frequency 16 kHz of MPEG-2 can not be reproduced.
¡VBR (Variable Bit Rate) is not supported.
¡The playback sound quality differs depending on the encoding software and the bit rate. For details refer to the user
manual of your encoding software.
■ Converting (encoding) audio data to an MP3 file
¡Do not record files other than MP3s or unnecessary folders on a disc. If many folders or files other than MP3s
are recorded on a disc, it may take some time before playback starts.
¡Use ISO 9660 file system (Extension of the ISO 9660 file systems are included.) (a page 31). APPLE HFS file
system is not supported. If they do not conform to ISO 9660 file system, the file may not play normally, or the file
or folder names may not be displayed correctly.
¡Make sure to add the “.mp3” extension to each MP3 file name. A file with a different file name extension or none
at all will not play.
¡Although Multi session recording is supported, the use of Disc-at-Once is recommended. Make sure to close the
session when you finished recording on a disc.
¡A disc recorded by the packet writing software are not supported.
¡A playlist function is not supported. Record files and folders in the order in which you want them to be played.
Some writing software lets you specify the recording order by adding a prefix in the range of “01” - “99”, etc. to the
file name. For details refer to the user manual of your writing software.
Notes:
¡You may encounter trouble in playing MP3s or displaying the information of MP3 files recorded with certain writing
softwares or CD recorders (CD-R/RW drives).
¡If a disc contains both MP3 and CD-DA, only CD-DA data is reproduced properly. (MP3 files are played but no
sound is output).
■ Recording MP3 files on a CD-R/RW
What is MP3?
MP3, short for MPEG-1 Audio Layer 3, MPEG-2 Audio Layer 3 LSF (Low Sampling Frequency), is a standard for compress-
ing digital video data adopted for video CDs and similar media. It is one of the audio compression systems covered by
MPEG's (Motion Picture Experts Group) digital audio compression standards. What it does is reduce the number of bytes
in a song without detracting from the sound quality by eliminating big sound waves within the sound range that is imper-
ceptible to the human ear. This compression allows you to reduce the contents of a conventional music CD by a factor of
around 10. This means that you can record the contents of 10 music CDs on a single CD-R or CD-RW. (The figures refer
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.)
Points to Remember When Recording an MP3 Disc
Warning: Never assign the “.mp3” file name extension to a file that is not in the MP3 format. This may produce
noise from the speakers and cause speaker damage and can damage your hearing.
Folder selection order/MP3 file playback order (Example)
Notes:
¡This unit counts the number of folders irrespective
of the presence or absence of MP3 file.
¡If the selected folder does not contain any MP3
files, the nearest MP3 files in the order of playback
will be played.
¡Playback order may be different from other MP3
players even if the same disc is used.
¡“ROOT” appears when displaying the root folder’s
folder name.
