developed by MPEG (Motion Picture Experts Group), and the
latter is developed by Microsoft Corporation. Using these

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/WMA encoding and CD writing software programs are

Points to remember when making MP3/WMA files
Common
¡
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.
MP3
¡ It is recommended to set the bit rate to "128 kbps or more"
and "fixed".
WMA
¡ It is recommended to set the bit rate to "64 kbps or more"
and "fixed".
¡
Do not set the copy protection on the WMA file to enable this
unit to play back.
Caution
¡ Never assign the ".mp3", or ".wma" file
name extension to a file that is not in the
MP3/WMA format. This may not only pro-
duce noise from the speaker damage, but
also damage your hearing.
