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.
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.
Phase knob and field: Define the phase of the modulation between the left and right channels of the reverb signal.
At 0°, the extreme values (minimum or maximum) of the modulation are achieved simultaneously on both the left and right channels.
At a value of 180°, the extreme values opposite each other (left channel minimum, right channel maximum, or vice versa) are reached simultaneously.
Intensity slider and field: Set the modulation amount. A value of 0 turns off the delay modulation.
Dry/Wet sliders and fields: Set the balance between the effect (wet) and original (dry) signals.
