Compressed audio files (MP3/WMA)
Terms
• MP3 — MP3 is short for Moving Pictures Ex-
perts Group Audio Layer 3. MP3 is the most
well-known compressed digital audio file for-
mat. 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 ap-
proximately a 10:1 ratio with virtually no percep-
tible 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 Microsoft
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 music file. The size
and quality of a compressed digital audio file is
determined by the bit rate used when encoding
the file.
• Sampling frequency — Sampling frequency is
the rate at which the samples of a signal are
converted from analog to digital (A/D conver-
sion) per second.
• Multisession — Multisession is one of the meth-
ods for writing data to media. Writing data once
to the media is called a single session, and
writing more than once is called a multisession.
• ID3/WMA Tag — The ID3/WMA tag is the part
of the encoded MP3 or WMA file that contains
information about the digital music file such as
song title, artist, encoding bit rate, track time
duration, etc. ID3 tag information is displayed
on the Artist/song title line on the display.
