Reshaper

The Reshaper effect is a special purpose dynamics modification program, designed to
"resculpt" the amplitude envelope of an audio signal. The effect uses an envelope
follower and threshold detector to drive an ADSR-type gain stage, which can impose
new attack, decay, sustain and release profiles on the signal's original envelope.

Applications

• "Punch" Reducer - slow turn-on with added lookahead trims attacks off signals
• "Punch" Enhancement - fast turn on with high thresholds and release gain
expands signal attack transients
• Auto Volume Pedal - long attack times with Attack Retrigger can automatically
simulate use of a guitar volume pedal for gently fading in each note.
• Ambience Reduction - can be used like a gate to suppress ambient reverberations
that below a certain threshold.
When the input signal exceeds an adjustable Threshold, the Attack phase begins and
continues until the gain reaches unity (0dB). After the Attack peaks, the gain stage
immediately transitions into the Decay phase, which continues until the gain falls to the
Sustain level. During the Sustain phase, the gain stage holds a constant level until the
input signal passes below the Release Threshold. During the Release Phase, the gain
returns to the Release Level where it remains until the another input transient triggers
the next Attack phase.
