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”.
