Bit rate

data recorded
in
a disc.
MP3 (MPEG AudioPiayer 3)
This
is
an
internationally
standardized audio data compression
scheme, using the
"MPEG-1"
video compression standard.
It
compresses the data
volume
to about one eleventh
its
original
size
while
maintaining sound quality equivalent
to
a music
CD.
Sampling
frequency
Sampling involves
taking a reading of a sound wave
(analog
signal) at
regular intervals
and
expressing the height of the
wave at each reading
in
digitized format (producing a
digital
signal).
The
number of readings taken
in
one second
is
called
the
"sampling
frequency". The
larger
the
value,
the
closer the
reproduced sound
is
to the
original.
