Adjustable
range: 0 to

Adjusts the attenuation
of
reflected sound.
You
can create
a lively sound field (with a high reverberant sound level)
as
you increase the value, and a dead sound field (with a
low reverberant sound level) as you decrease the value.
Creating either a lively sound field or a dead sound field in
an actual music hall
is
determined
by
the acoustic
absorption characteristics
of
reflection surfaces. A dead
sound field
is
created when the attenuation time is short
while a lively sound field
is
created when the attenuation
time
is
long.

You

Room Size
Adjustable
range:
0.1
to
2.0
Produces different senses
of
sound expansion according to
room sizes specified.
In
a large size room such
as
a music
hall, the duration from when reflected sound is heard until
when the next reflected sound
is
heard
is
long. Thus,
different senses
of
sound expansion can be created by
changing the duration. 1.0 is the original room size. When
this parame:ter
is
set to 2.0, each side
of
the room is
defined as twice larger than the original room size.
