CHAPTER 52
SPL Transient Designer
Overview
Universal Audio has partnered with German company Sound Performance 
Lab (SPL) to bring you the Transient Designer, with its unique and compelling 
Differential Envelope Technology for shaping the dynamic response of a 
sound. Only two simple audio controls are required to allow you to effortlessly 
reshape the attack and sustain characteristics. SPL was the first company to 
design an analog solution for level-independent shaping of envelopes, 
allowing transients to be accelerated or slowed down and sustain prolonged 
or shortened.
You can shorten or lengthen the attack and sustain of percussive signals such 
as kick drum, snare or toms, easily take the bleed from open mics, or expand 
the room sound of overheads. The Transient Designer’s magic can be applied 
to virtually any other signal as well: Amplify or reduce the picking sound of an 
acoustic guitar, hold the sound of strings longer, or reduce the reverb time of 
a choir.
