AUDIO OPERATION PRECAUTIONS
Compact Disc with MP3
Terms:
cMP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is themost 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 a 10:1 ratio 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.
cBit 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.
cSampling frequency — Sampling frequency
is the rate at which the samples of a signal
are converted from analog to digital (A/D
conversion) per second.
cID3 tag — The ID3 tag is the part of the
encoded MP3 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.Playback order:
Playback order of the CD with compressed files
(MP3) is as illustrated above.
cThe names of folders not containing MP3
files are not shown in the display.
