Notes on MP3/DivX

What is MP3/DivX?
MP3:
MP3 (MPEG Audio Layer-3) is the compression
format of digital audio. It is developed by MPEG (Motion
Picture Experts Group). Using this compression format,
the contents of about 10 music CDs can be recorded on a
single CD (This figure refers to data recorded on a 650
MB CD-R or CD-RW at a fixed bit rate of 128 kbps and a
sampling frequency of 44.1 kHz).
Setting at file making
Common
¡
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
software.
¡
Be sure to put an extension compatible with the for-
mat.
¡
It is recommended that the length of the file name is
less than 8 characters (excluding the file extension).
