What are MP3/WMA/AAC?
MP3 is an abbreviation of “MPEG-1 Audio
Layer 3”. MPEG is an abbreviation of
“Motion Pictures Experts Group”, which is
a standard for compressing digital video
data for use in media such as video CDs.
MP3 is one of the audio compression
schemes covered by the MPEG digital
audio compression standards. MP3 com-
pression reduces the number of bytes in
a song by eliminating large sound waves
within the sound range that is impercep-
tible to the human ear, producing high
quality audio fi les with a low volume of
data. MP3 compression allows for the
contents of a conventional music CD to
be reduced by a factor of about 10. This
means that the contents of 10 music CDs
can be recorded on a single CR-R or CD-
RW.
WMA is an abbreviation of Windows Me-
dia Audio, which is another audio com-
pression standard.
WMA can be used to create and save au-
dio fi les at a higher compression rate than
with MP3.Microsoft, Windows Media, and Microsoft Corporation are regis-
tered trademarks in the United States and/or other countries.
· AAC is an abbreviation of Advanced Audio Coding, which is a compressed audio format in which the
video compression standards MPEG-2 and MPEG-
4 are used. The compression rate is about 1.4 times
that of MP3 and maintains almost the same sound
quality.
NOTE
· WMA and AAC support Digital Rights Management
(DRM).This audio system cannot play WMA or AAC
fi les, which are protected under DRM.
