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.
