EnVerb sound parameters
• 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.
Logic Pro SilverVerb
SilverVerb provides a low frequency oscillator (LFO) that can modulate the reverberated
signal. It also includes a high cut and a low cut filter, allowing you to filter frequencies from
the reverb signal. High frequency transients in reverb signals can sound unpleasant, can
hamper speech intelligibility, or can mask the overtones of the original signal. Long
reverb tails with a lot of bass generally result in an indistinct mix.
SilverVerb parameters
• Predelay knob and field: Set the time between the original signal and the reverb signal.
• Reflectivity knob and field: Define how reflective the imaginary walls, ceiling, and
floor are.
• Size knob and field: Define the dimensions of the simulated room.
• Density/Time knob and field: Determine both the density and the duration of the reverb.
• Low Cut slider and field: Filter frequencies below the set value out of the reverb signal.
This affects only the tone of the reverb signal, not the original signal.
• High Cut slider and field: Filter frequencies above the set value out of the reverb signal.
This affects only the tone of the reverb signal, not the original signal.
• Modulation On/Off button: Enable or disable the LFO. This affects the Rate, Phase, and
Intensity parameters.
• Rate knob and field: Set the frequency, or speed, of the LFO.
