Sampling
if
"Synthesizing"
can
create
a wide
variety of
sounds, but
it
is
often very
difficult
to
synthesize
natural
sounds. "Sampling"
is
a completely
different
method,
which
is
recording
real
sounds which can be
modified.
Attack

It
is difficult
to
make such waveforms by combining
sine
waves and saw
tooth waves.

When
the

down, wave-forms
become
gentle.
The
S-330's
sampling
is
conceptually
like
a tape recorder
in
that
it
records
sounds.
However,
the recording
process
is
very
different
since the S-330
is
recording
into
computer memory.
This
is
called
a
PCM
sampling system,
which
is
used
not only
for
samplers
but also
for
rhythm
machines
or
digital
effects
such as
digital
delays.
The
PCM
recording converts audio
signal
into
digital.
It
does
this
by examining
(sampling) the
incoming
signal
level
a great
many
times
each
second,
and
sequentially recording these
different levels
in
computer memory. The Sampling
frequencies are the
number
of
times per
second
that
a
sample
is
made
of
the input signal.
The S-330 can sample
either at
30,000
or
15,000
samples
per
second
(30
or 15kHz).
