■ MP3, WMA and AAC files

Files can be compressed to approxi-
mately 1/10 of their original size by
using MP3 compression.
WMA (Windows Media Audio) is a
Microsoft audio compression format.
This format compresses audio data to a
size smaller than that of the MP3 format.
AAC is short for Advanced Audio Cod-

technology standard used with MPEG2
and MPEG4.
There is a limit to the MP3, WMA and
AAC file standards and to the media/for-
