Acceptance of the fi les
Some blank CDs may not be played

When you burn a CD-R or CD-RW,
select the ISO 9660 level 1.2 or Joliet
burning standard.
To obtain the best acoustic quality pos-
sible, select the lowest burning speed.
The MPEG1 and MPEG2 standards
are accepted.
Transmission speeds between 32 and
320 kbits/s and scans between 16 kHz
and 48 kHz are accepted.
To display the title information (the name
of the artist, the title of the album, etc...),
the information contained in the ID3 Tags
or the WMA Tags must be included in the
MP3/WMA fi les burned onto the disc.
What is the MP3/WMA fi le format?
MP3 is the abbreviation of MPEG-1
Audio Layer 3 and MPG is the abbrevia-
tion of Motion Pictures Experts Group, a
digital video data compression standard
used on media such as video CDs.
The MP3 compression reduces the
number of bytes in a song by eliminating
the long sound waves in the range of fre-
quencies which are imperceptible to the
human ear, so producing high quality au-
dio fi les with a low volume of data.
This compression divides the size of
the content of a conventional audio CD
by approximately 10, which means that
the content of 10 audio CDs can be
recorded onto a single CD-R or CD-RW.
WMA is the abbreviation of Windows
Media Audio, another audio data com-
pression standard offered by Microsoft.
It can be used to create and save audio
fi les at a compression rate higher than
that of the MP3 format.
