2-3 The basic elements of sound
synthesis
© Waveforms
The
waveforms
talked
about
here
are
the
unfiltered
simple
waveforms
that
form
the
basis
of
sound
synthesis.

By
using
a
filter
this
waveform
may
be
turned
into
a
sine
wave.
This
waveform
may
be
thought
of as being
the
most
basic
or
standard.
It has
a soft
rounded
tone
color
which
makes
it
appropriate
for
such
sounds
as a flute,
piccolo,
or organ.

Since
there
is
a
certain
amount
of
upper
harmonic
elements
in
this
waveform,
it
is
easy
to
use
filtering
to
produce
a
wide
variation
in
sound
quality.

Since
this
waveform
does
not
contain
even
harmonic
elements,
the
sound
quality
is on
the
heavy,
dull
side.
