MP3 is a compression form (like zip). The name MP3 stand for Mpeg1 Audio layer 3 and its compression
algorithm is based on a complicated psycho-acoustic model. This model is based on the fact that the human
ear can not hear all the audio frequencies. The human hearing range is between 20Hz to 20khz and it is
most sensitive between 2 to 4 kHz. As a result the MP3 compression form is destructive, that means the
compression algorithm causes the file to lose some information so that it can not be restored to its original
content.

When compressing an audio file (encoding) using the MP3 algorithm you can set the desired encoding level
and have any compression level you want. The larger the compressed file the better the audio quality of the
result. The majority of the files available on the internet are encoded in 128 kbits stereo 44kHz which results
in a high quality file that is 12 times smaller than the original!  This, of course, has many 
interesting consequences.

When creaing MP3’s to play on your DVD player, be sure to change the Character Settings from 
Joliett to ISO 9660 in your “CD Format” properties of you favorite CD-R burning software.

For those of you using Adaptec® Easy CD Creator® 3.5 or higher, be sure to change the Mode Settings
from Mode 2 to Mode 1.

Note: The AD-600A DVD player will not play MP3 files on a CD-RW.
