Compressed Audio Files (MP3/
WMA/AAC)
Explanation of 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
can reduce the file size by approxi-
mately a 10:1 ratio (Sampling: 44.1
kHz, Bit rate: 128 kbps) with virtually
no perceptible loss in quality. The
compression reduces certain parts of
sound that seem inaudible to most
people.
. WMA —Windows Media Audio (WMA) is
a compressed audio format created by
Microsoft as an alternative to MP3. The
WMA codec offers greater file compres-
sion 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.
. AAC/M4A —Advanced Audio Coding
(AAC) is a lossy audio compression
format. Audio files that have been

. ASF - ASF stands for Advanced Systems
Format. It is a file format owned by
Microsoft Corporation. Note: Only “.
asf” files that meet the requirements
stated in the table in this section can
be played.
