Compact Disc (CD) with MP3 or WMA
(if so equipped)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 from CD-ROM can reduce the
file size by approximately 10:1 ratio (Sam-
pling: 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.
.WMA — Windows Media Audio (WMA) is acompressed audio format created by Micro-
soft 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 files.
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
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.
