EnVerb is a versatile reverb effect with a unique feature: it allows you to adjust the envelope—the shape—of the diffuse reverb tail. EnVerb is divided into two areas:
Time parameters: The graphic display shows and lets you adjust levels over time (the envelope) of the reverb. You can control the delay time of the original signal and can change the reverb tail over time.
Sound parameters: The controls below the envelope display shape the sound of the reverb signal. You can split the incoming signal into two bands with the Crossover parameter and can set the low frequency band separately.
Drag parameter handles directly in the envelope display, or drag vertically in parameter fields to adjust EnVerb values.
Attack handle and field: Set the time it takes for the reverb to climb to its peak level.
Decay handle and field: Set the time it takes for the level of the reverb to drop from its peak to the sustain level.
Sustain (Hold) handle and field: Drag vertically to set a constant reverb level for the sustain phase. It is expressed as a percentage of the full-scale volume of the reverb signal. See Hold parameter.
Release handle and field: Set the time it takes for the reverb to fade out completely, after the sustain phase.
Dry Signal Delay handle and field: Determine the delay of the original signal. Set a suitable level with the Dry slider in the Mix section.
Predelay field: Set the time between the original signal and the start point of the reverb attack phase—the very beginning of the first reflection.
Hold (Sustain) handle and field: Drag horizontally to set the duration of the reverb sustain phase. See Sustain parameter.
Density knob and field: Set the reverb density.
Spread knob and field: Control the width of the reverb stereo image. At 0% the effect generates a monaural reverb. At 200% the stereo base is artificially expanded.
High Cut knob and field: Filter frequencies above the set value out of the reverb tail.
Crossover knob and field: Set the frequency used to split the input signal into two frequency bands for independent processing.
Low Freq Level knob and field: Set the relative level of (reverb signal) frequencies below the crossover frequency. In most cases you get better-sounding results when you set negative values for this parameter.
Dry/Wet sliders and fields: Determine the balance between the effect (wet) and direct (dry) signals.
