Cautions as to compressed audio files
¡ 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 encoding circumstances. For details, refer to
