Notes on MP3
MP3 (MPEG Audio Layer-3) is a format for compressed audio file. These formats allow users to save all the
files contained in approximately 10 pieces of existing CDs on one piece of CD-R/RW.
Note: Each of encoding software is not included with this unit.
*MPEG Layer-3 audio coding technology licensed from Fraunhofer IIS and Thomson.
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 playback sound quality differs depending on
the encoding circumstances. For details, refer to
the user manual of your own encoding software
and writing software.
¡ Be sure to put an extension compatible with the
format.
¡ It is recommended to set the bit rate to “128 kbps
or more” and “fixed”.
Compression formats
Compression method Bit rate VBR Sampling frequency
MPEG 1 audio layer 3 (MP3) 32 k – 320 kbps Yes 32, 44.1, 48 kHz
MPEG 2 audio layer 3 (MP3) 8 k – 160 kbps Yes 16, 22.05, 24 kHz
MPEG 2.5 audio layer 3 (MP3) 8 k – 160 kbps Yes 8, 11.025, 12 kHz
Caution
Never put an extension indicating compressed audio (such as “.mp3”) to files other than compressed
audio files. This may not only produce noise from the speaker damage, but also damage your hearing.
