Using MP3/WMA Player
Audio Operations
■ Converting music CD into MP3/WMA files
Prepare a PC and a commercially available MP3/WMA encoder (conversion) software (some
of them are free). Load a music CD on the PC's CD-ROM drive and compress the music CD by
following the procedure of MP3/WMA encoder software. MP3/WMA-format music data files are
created. A 12 cm music CD (having a maximum of 74 minutes of recording/650 MB of data) can
be compressed to 65 MB (about 1/10 of the original size).
■ Writing MP3/WMA files on CD-R/RW disc
MP3/WMA files can be recorded on CD-R/RW by using a CD-R/RW drive connected to a
computer. Record by setting the recording format of the recording software to ISO9660 level 1
or level 2 (not including extension format).
Select CD-ROM ( mode1 ) or CD-ROM XA ( mode2 ) for the disc format.
■ Playing back CD-R/RW
Insert a CD-R/RW disc having recorded MP3/WMA files. When you load a disc, the system
automatically determines whether it is a music CD or a CD-R/RW disc having MP3/WMA files
and plays it correctly. However, depending on the type of disc being used, the disc may not
play.
● The 128K bps fixed bit rate and 44.1-kHz sampling frequency are recommended for high quality
sound on playback.
● Note that some CD-R and CD-RW discs may not be read due to their characteristics.
● There are many types of MP3/WMA encoding software available, including commercial and
freeware programs. Depending on the condition of the encoder and the file format, audio quality
may deteriorate, noise may be generated when playing starts and some recordings may not
play.
● When files other than MP3/WMA files are recorded on a disc, the system may take some time
to recognize the disc and it may not play the disc.
