AUDIO/VISUAL SYSTEM

Level 2: The file name can have up to 31
characters (including the separation mark
“.” and file extension). Each folder must
contain fewer than 8 hierarchies.
 MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
 WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft
®. It compresses files into a size
smaller than that of MP3 files. The decod-
ing formats for WMA files are Ver. 7, 8 and
9.

MP3/WMA/AAC FILES
MP3 (MPEG Audio LAYER3) is a stan-
dard audio compression format. Files
can be compressed to approximately
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 for-
mat.
AAC (Advanced Audio Coding) is a
standardized the audio compression
type that is designed to be the succes-

achieves good sound quality and high-
compression than MP3 at similar bit
rates.
