General notes on MP3/WMA CDs


What is the MP3/WMA fi le format?

MP3 is the abbreviation of MPEG-1 Audio Layer 3 and MPG is the
abbreviation 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 frequencies which
are imperceptible to the human ear, so producing high quality audio
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 compression 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.
Acceptance of the fi les

Some blank CDs may not be played by your equipment (quality,
recording speed...).
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 possible, 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.
