UAD Powered Plug-Ins Manual - 306 - Chapter 36: SPL Transient Designer
SPL Transient Designer Controls
Containing only two primary controls, the UAD SPL Transient Designer is ex-
tremely simple to operate. The technology behind the processor isn't as im-
portant as how it sounds. However, for those who desire a deeper under-
standing of the process, a deeper explanation of the underlying technology is
presented at the end of this chapter (see “Technology” on page 312).
Attack Attack enables amplification or attenuation of the
attack of a signal by up to ±15dB.
The Attack control circuitry uses two envelope gen-
erators. One follows the shape of the original curve
and adapts perfectly to the dynamic gradient. The
second envelope generator produces an envelope
with a slower attack. From the difference of both en-
velopes the VCA control voltage is derived. Positive Attack values emphasize
attack events; negative values smooth out the attack envelopes of sound
events.
For more information, see “The ATTACK Control Circuitry” on page 312)
Sustain Sustain enables amplification or attenuation of the
sustain of a signal by up to ±24dB.
The Sustain control circuitry also uses two envelope
generators. One follows the shape of the original
curve and adapts perfectly to the dynamic gradi-
ent. The second envelope generator produces an
envelope with a longer sustain. From the difference of both envelopes the
VCA control voltage is derived. The gradient of the control voltage matches
the time flow of the original signal. Positive Sustain values lengthen the sus-
tain; negative values shorten the sustain.
For more information, see “The SUSTAIN Control Circuitry” on page 314.
Gain Gain controls the signal level that is output from the plug-in.
The available range is from -20dB to +6dB. The default
value is 0dB.
