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 approximately 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 com-
pared to MP3s at the same level of
quality.
This product is protected by certain
intellectual property rights of Microsoft
Corporation and third parties. Use or distribution of such technology outside
of this product is prohibited without a
license from Microsoft or an authorized
Microsoft subsidiary and third parties.
. 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 fre-
quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
. 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.
. 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,
album title, encoding bit rate, track time
duration, etc. ID3 tag information is
displayed on the Album/Artist/Track
title line on the display.
