UAD Powered Plug-Ins Manual - 516 - Chapter 52: SPL Transient Designer
• Shorten the sustain period of a snare or a reverb tail in a very musical way 
to obtain more transparency in the mix.
• When recording a live drum set, shorten the toms or overheads without 
physically damping them. Usual effor
ts to damp and mike are reduced re-
markably. Since muffling of any drum also changes the dynamic response, 
the Transient Designer opens up a whole new soundscape.
• Micing live drums is considerably faster and easier because you can correct 
the apparent “distance” of the microphone by simply var
ying the ATTACK 
and SUSTAIN values.
• The Transient Designer is a perfect alternative to noise gates in live drum 
micing. Adaptively reacting to the duration of the original signal, the sustain 
is shor
tened more musically than with fixed release times and a drumset is 
freed from any crosstalk quickly and effectively.
• Create unusual dynamic effects including new and interesting pan effects. 
For example, patch a mono loop through two channels of the T
ransient De-
signer and pan fully left and right in the mix. Process the left channel with 
increased ATTACK and reduced SUSTAIN while you adjust the right chan-
nel the opposite way and you get very special stereo loop sounds. You have 
to try this to appreciate what it sounds like, but expect to hear a lot of un-
usual stereo movement.
• Enjoy an amazingly simple integration of drum sounds into a mix. If the 
acoustic level of a snare is expanded to approximately +4 dB by increasing 
the attack value, the effective increase of peak levels in the overall mix is 
merely about 0.5 dB to 1 dB.
Drums: 
Ambience
If your drums happen to sound as if the room mics have been placed in a shoe 
closet, the Transient Designer can immediately turn that sound into the ambi-
ence of an empty warehouse. Just send the stereo room mics through the Tran-
sient Designer and crank the ATTACK control to emphasize the first wave.
Now slowly increase SUSTAIN values to bring up an “all-buttons-in-1176-
sound” room tone—but without pumping cymbals. For a solid and driving 
rhythm track just fine-tune the SUSTAIN control to make sure that the room mic 
envelope ends more or less exactly on the desired upbeat or downbeat.
