Compressors, Expanders, and Gates
9-15
SmoothTime
smooths
the
output
of
the
expander’s
envelope
detector
by
putting
a
lowpass
filter
in
the
control
signal
path.
Smoothing
will
affect
the
Attack
or
Release
times
only
when
this
parameter
is
longer
than
one
of
the
other
times.
The
range
is
0.0
to
228.0
ms.
Signal
Dly
(Delay)
puts
a
small
delay
in
the
signal
relative
to
the
sidechain
processing,
so
that
the
compressor
(or
gate)
“knows”
what
the
input
signal
is
going
to
be
before
it
has
to
act
on
it.
This
means
the
compression
can
kick
in
before
an
attack
transient
arrives.
In
the
SoftKneeCompress
and
HardKneeCompress
algorithms,
delay
is
really
only
useful
in
feed
‐
forward
configuration
(FdbkComprs
is
“Out”).
For
other
compressors,
the
delay
can
be
useful
in
feedback
configuration
(FdbkComprs
is
“In”).
The
range
is
0
to
25
ms.
Ratio
is
the
amount
of
gain
reduction
imposed
on
the
compressed
signal,
adjustable
from
1.0:1
(no
reduction)
to
100:1,
and
Inf:1.
Threshold
is
the
level
in
dBFS
(decibels
relative
to
full
scale)
above
which
the
signal
begins
to
be
compressed.
Adjustable
from
‐
79.0
to
0
dB.
MakeUpGain
allows
additional
output
gain
to
compensate
for
gain
reduction
in
the
compressor.
It
is
essentially
the
same
parameter
as
Out
Gain,
with
which
it
is
summed.
The
minimum
is
‐
79.0,
and
the
maximum
summed
gain
(MakeUpGain
+
Out
Gain)
is
+24.0
dB.
Expansion
Algorithms
containing
Expanders
have
these
controls:
Atk
or
Exp
Atk
(Attack),
how
fast
the
expander
turns
off
when
the
input
signal
rises
above
the
threshold
level,
adjustable
from
0.0
to
228.0
ms.
Rel
or
Exp
Rel
(Release),
how
fast
the
expander
turns
back
on
after
the
signal
drops
below
the
threshold
level,
adjustable
from
0
to
3000
ms.
Ratio
or
Exp
Ratio
,
how
much
the
gain
is
reduced
below
the
expansion
threshold,
adjustable
from
1:1.0
(no
expansion)
to
1:17
(extreme
downward
expansion).
Threshold
or
Exp
Threshold
,
the
level
below
which
the
signal
is
expanded,
adjustable
from
‐
79.0
to
0
dB.
In
addition,
the
two
‐
segment
compressors
with
expander
have
separate
Ratio
and
Threshold
controls
for
each
of
the
compression
segments.
Multiband Compression
The
Multiband
Compression
algorithm
has
Attack
,
Release
,
Smooth
,
Signal
Delay
,
Ratio
,
Threshold
,
and
MakeUp
Gain
parameters
for
each
of
the
three
bands
(“Low”,
“Mid”,
and
“High”).
In
addition,
it
has:
Crossover1
and
Crossover2
.
These
set
the
frequencies
which
divide
the
three
compression
frequency
bands.
The
two
parameters
are
interchangeable,
so
either
may
contain
the
higher
frequency
value.
The
range
is
16
to
25088
Hz,
in
increments
of
a
semitone.
Gates
SC
Input
lets
you
select
which
input
channel(s)
will
control
the
sidechain,
which
is
responsible
for
opening
and
closing
the
gate.
It
can
be
set
to
L,
R,
or
the
average
of
the
two
channels,
(L+R)/2.
You
can
use
this,
if
you
arrange
the
signal
paths
and
pan
controls
appropriately,
to
gate
one
mono
signal
with
a
different
mono
signal—the
venerable
“Keyfex”
effect.
Gate
Time
is
the
time
that
the
gate
will
stay
open
after
the
sidechain
signal
reaches
the
Threshold.
Its
range
is
0
to
3000ms.
