Frequency Damping – Low & High
These two parameters allow you to control the equalization of the reverb’s decay
separately for both the low and high frequencies. This means that you have control
over the tonal shape of the Reverb itself over time, being able to cut the high
frequencies if the effect is too bright, and being able to cut the lows if the effect is too
boomy. These parameters allow you to simulate different surfaces of a room or hall,
with softer surfaces absorbing high frequencies and harder rooms (parking garages,
tiled rooms) diffusing low frequencies. Example: If a room has lots of hanging drapes,
the high frequencies will decay faster than the lower frequencies.

Note that the Low Pass Frequency and High Damping parameters are related. If your
LPF is set for 8kHz, and the High Damping parameter is set above 8kHz, you won’t
hear much of a change from this parameter. This is because the high frequencies have
already been rolled off, so there’s nothing left to filter. In most cases, make sure that
the LPF is set above the high damping frequency to get the most out of this effect.
However, since reverb is a random function, some high frequencies can be generated
over the course of a long decay which are higher than the LPF. In these cases, setting
the High Damping at the same frequency or higher than the LPF will attain audible
results. In either case, by using the LPF and High Damping in conjunction, you can
yield a more authentic room sound.

ER: Early Reflections (Spread, Shape and Level)
The Early Reflections of a reverb add attack to the room and dictate the room’s size.
The Shape parameter controls how the reflections fade out over time. Different
shapes will dictate the shape of the room and the intensity of the attack. The Early
Reflection shapes are diagramed below:
