Terms ∙ MP3 — MP3 is short for Moving Pictures Experts Group Audio Layer 3. MP3 is the
most well-known compressed digital
audio file format. This format allows for
near “CD quality” sound, but at a fraction
of the size of normal audio files. MP3
conversion of an audio track from CD-
ROM can reduce the file size by approxi-
mately a 10:1 ratio with virtually no per-
ceptible loss in quality. MP3
compression removes the redundant
and irrelevant parts of a sound signal
that the human ear doesn’t hear.
∙ WMA — Windows Media Audio (WMA)* is a compressed audio format created by
Microsof t as an alternative to MP3. The
WMA codec offers greater file compres-
sion than the MP3 codec, enabling stor-
age of more digital audio tracks in the
same amount of space when com-
pared to MP3s at the same level of qual-
ity.
