Terms
• MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well-known compressed digital au-
dio 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 re-
duce the file size by approximately a 10:1
ratio with virtually no perceptible 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 Mi-
crosof t as an alternative to MP3. The WMA
codec offers greater file compression
than the MP3 codec, enabling storage of
more digital audio tracks in the same
amount of space when compared to
MP3s at the same level of quality.
