Transient Designer 4

The Original.

The Transient Designer has created a new breed of dynamics processors that can shape the transient response of any audio signal.

Transient Designing

The Transient Designer revolutionizes dynamics processing by allowing level-independent (no threshold!) editing of envelopes for the first time.

Accelerate or slow down transients, lengthen or shorten decay times with just two controls (attack and sustain).

All time constants are automated in a musical way and optimize themselves adaptively according to the characteristics of the input signal.

Channels 1 & 2 as well as 3 & 4 can be linked for processing stereo signals. The respective left channel becomes the master.


The attack control can be used to boost or cut the attack phase of a signal by up to 15 dB. 

A positive attack value increases the amplitude of the transient response. Negative attack values lead to an attenuation.


The Sustain control can be used to boost or cut the decay phase of a signal by up to 24 dB. 

Positive sustain values extend the decay. Negative Sustain values shorten the decay.

Ryan Hewitt

“The Transient Designer has changed my working life.”

Ross Hogarth

“I am a huge fan and use it on every project I do … nothing else does what it does.”

Ed Cherney

“I love my Transient Designer, I need more channels!”

Joe Chicarelli

“It is truly one of the most unique pieces of gear any mixer can have.”

The Differential Envelope Technology

Our Differential Envelope Technology (DET) allows dynamic signal characteristics to be processed by forming the difference between envelopes and thereby making them level-independent.

The envelope trackers align the working processes with the natural signal characteristics. This ensures optimum results for every moment. 

Attack... that's how it's done:

Sustain ... that's how it's done:

Inputs & Outputs

The four channels of the Transient Designer are equipped with Neutrik XLR sockets with gold-plated contacts. The signal transmission is electronically balanced at a nominal level of +6 dB.
