What are MP3/WMA?
MP3 is an abbreviation of “MPEG-1 Audio
Layer 3”. MPEG is an abbreviation of “Mo-
tion 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 imperceptible
to the human ear, producing high quality
audio 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 Media
Audio, which is another audio compression
standard.
WMA can be used to create and save au-
dio les at a higher compression rate than
with MP3.
