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-
sor of the MP3 format. AAC generally
achieves good sound quality and high-
compression than MP3 at similar bit
rates.
There is a limit to the MP3, WMA and
AAC file standards and to the media/
formats recorded by them that can be
used.
