Terms:
O MP3 — MP3 is short for Moving Pic-
tures Experts Group Audio Layer 3.
MP3 is the most well known com-
pressed 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 can reduce the
file size by approximately 10:1 ratio
(Sampling: 44.1 kHz, Bit rate: 128
kbps) 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.
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
compression than the MP3 codec, en-
abling storage 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
music files. The size and quality of a
compressed digital audio file is deter-
mined by the bit rate used when en-
coding the file.
O Sampling frequency — The rate at
which the samples of a signal are con-
verted from analog to digital (A/D con-
version) 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 multises-
sion.
O 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.
