 Size: Determines the room size. Moving the slider to the left means the
smallest size, moving it to the right extends the reflection times. Smaller "Size"
settings also reduce the distance between the individual reflections.
Resonance may also develop due to the short temporal distance between
them. Increasing the size of the room creates more space,but this also means
that the so-called "modal density" decreases, i.e. more time will pass before
the impression of a confined room develops.
 Diffusion: With this parameter, you can simulate diffusion on irregular walls
and objects. The higher the value, the softer and fuller the reverb sounds.
 ER absorption: VariVerb calculates 16 initial reflections (compiled to 8 in the
display). This controller lets you specify how broadly the last ones are
weighted. A lower value results in a more "lively" sound impression, although
this may also have a more intrusive or unsettled effect. A higher degree of
absorption indicates a smaller amplitude as well as damping of highs.
 ER tail: The mixing ratio for the early reflections and subsequent reverberation.
These reverberations are decisive for perception of the room size. Mixing them
into the actual reverb improves the possibility of locating voices or
instruments. Missing reflections at the start often result in "spongy" sound
characteristics without orientation in "room" and "depth".
 Decay: The reverberation time. Use this controller to define how fast the
reverb tail will be absorbed, i.e. the time for the reverb to ring out. Turning this
knob to the left minimizes the time, you might only hear the first reflections.
Turning the knob to the right minimizes damping and results in long, sustained
reverberation.
 High freq: The threshold where the "high damp" effect starts.
 High damp: Allows you to influence the frequency-dependent absorption of
the reverb. A higher value dampens the highs and upper mids similar to the
absorption effect of the air and in particular the material composition of walls.
 Width: Specifies the width of the stereo effect. If set to left, the reverb is
monaural.
Plate
A real plate reverb consists of a large metal plate (often 0.5 to 1 m² or more),
that is activated by a magnet and coil system (similar to a loudspeaker). The
plate is normally hung on springs so that it is able to oscillate freely. Various
types of damping are possible to reduce the reverb time. The reverb plate
features so-called "taps" at various locations. These are sound pickups similar
to those on a guitar. Several of these taps are combined to produce a full
signal. Reverb plates are usually mono, i.e. a stereo signal is added to the
plate as a sum. A (pseudo-)stereophonic signal is created by combining taps
and their position on the plate.
Real reverb plates are only rarely used today and have been almost entirely
replaced by software simulation. The sound continues to be very popular due
to the very dense sound (high diffusion) and inaudible discreet echoes.
