Universal Audio has partnered with Germany’s 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. Two simple audio controls allow effortless reshaping of 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.
