Digital sampling is an electronic process
used in telecommunications for transforming a
constantly varying analog signal into one
composed of discrete units, a digital signal.
In the creation of recorded music, sampling
enables the composer, producer, or remix
engineer to borrow discrete vocal or
instrumental parts from other recorded work
(it is also possible to sample live sound).
A telephone microphone changes sound waves
into an analog signal that fluctuates up and
down like a wave. In the digitizing process
the waveform is sampled thousands of times a
second and each part of the sampled wave is
given a binary code number (made up of
combinations of the digits 0 and 1) related
to the height of the wave at that point,
which is transmitted along the telephone
line. Using digital signals, messages can be
transmitted quickly, accurately, and
economically.
