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 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.
∙ Bit rate — Bit rate denotes the number of bits per second used by a digital mu-
sic file. The size and quality of a com-
pressed digital audio file is determined
by the bit rate used when encoding the
file.
