Explanation of terms:
O 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 frac-
tion of the size of normal audio files.
MP3 conversion of an audio track from
CD-ROM can reduce the file size by ap-
proximately 10:1 ratio with virtually no
perceptible loss in quality. MP3 com-
pression removes the redundant and ir-
relevant parts of a sound signal that the
human ear doesn’t hear.
O 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 stor-
age of more digital audio tracks in the
same amount of space when compared
to MP3s at the same level of quality.
O 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.
O Sampling frequency Sampling fre-
quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
O Multisession Multisession is one of
the methods 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.
O ID3/WMA Tag The ID3 tag is the part
of the encoded MP3 or WMA file that
contains information about the digital
music file such as song title, artist,
album title, encoding bit rate, track
time duration, etc. ID3 tag information
is displayed on the Album/Artist/Track
title line on the display.
