❐Points to remember when making MP3 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 playback sound quality differs depending on the encoding circumstances. For details, refer to the user manual of your own encoding software and writing software.
Caution:
≥It is recommended to set the bit rate to “128 kbps or more” and “fixed”.
≥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.
