Notes on MP3
Note: MP3 encoding and writing software is not supplied with this unit.
Points to remember when making MP3 files
¡High bit rate and high sampling frequency are recom- mended for high quality sounds.
¡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 user manual of your own encoding software and writing soft- ware.
¡It is recommended to set the bit rate to “128 kbps or more” and “fixed”.
Caution
Never assign the “.mp3”, file name extension to a file that is not in the MP3 format. This may not only produce noise from the speaker dam- age, but also damage your hearing.
