❐ What is MP3?
≥ 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.
≥ 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 damage, but also damage your hearing.
