2] SOBE/SOUND SYNTHESIS
2-1 Thinking about sound synthesis
First analyse the sound you want to
synthesize.
Ask yourself: What is the pitch, the tone
color, and the volume of the sound? How
do these qualities change over time?
You must break down the sound into its
basic elements if you want to be able to
recreate it on the synthesizer control panel.
Get into the habit of doing this all the
time. When you hear a car turning a corner
on a wet road, a large bird flapping its
wings, a bullet whistling past your ear, a
transistor radio knocked into a swimming
pool, or someone's footsteps on the stairs,
analyse it in your head and figure out how
to synthesize it.

Let's
take
the
time
signal
recorded
on
the
demonstration
tape
as
an
example
and
try
to
analyze
it
and
then
recreate
it.
(This
time
signal
is
used
by
Japanese
radio
stations.)
The
time
signal
is made
up
of a combina
tion
of two
types
of different
tones,
three
short
ones
and
one
long
one.
One
very
obvious
difference
between
the
two
sounds
is their
envelope,
another
is their
pitch.
The
final
long
tone
fades
away
over
a long
period
of time
while
the
three
initial
short
tones
end
very
abruptly.
You
may
be
able
to
tell
from
experience
that
the
differen
in
pitch
between
the
two
sounds
is
a
mat
ter
of one
octave.
What
about
a difference
in
tone
color
or
timbre?
Is
change
or
are
the
sounds
basically
same?
One
thing
that
can
be
said
about
these
tones
is that
they
have
a rounded
quality. Now let's try and recreate these
sounds,
