Notes on MP3/WMA
G What is MP3/WMA?
MP3 (MPEG audio layer 3) and WMA {Windows Media™ Audio) are the compression formats of digital audio.
The former is developed by MPEG (Motion Picture Experts Group), and the latter is developed by Microsoft
Corporation. Using these compression formats, you can record the contents of about 10 music CDs on a sin­
gle CD media. (This 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.)
Note:
• MP3/WMA encoding and writing software are not supplied with this unit.
• CD writing software is not supplied with this unit.
G Points to remember when making MP3/WMA files
Common
• High bit rate and high sampling frequency are
recommended for high quality sounds.
• Selecting VBR (Variable Bit Rate) is not recom­
mended 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 user manual 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 protect attribute on the WMA
file to enable this unit to playback.
Caution:
• Never assign the “.mp3”, or “.wma" file name extension to a tile that is not in the MP3/WMA format.
This may not only produce noise from the speaker damage, but also damage your hearing.
