Early & Late (Reverb) Shaping
Level
This parameter acts as a master level control for signals going to the output channels. Both
early signals and late (reverb tail) signals can be controlled individually. Early signals include
echoes and reflections.
Early level may be adjusted for any of a few reasons. Increasing the early level (depending on
settings for reflections and echoes) might increase the sense that the microphone is closer to
the source audio. By the same token, decreasing the reverb level may accomplish the same
thing. Lowering the early level might be called for if the source audio has been recorded in a
natural space with strong reflection characteristics. If the user is sweetening a track by adding
just a little bit of reverb to a pre-existing natural reverb, then lowering the early level might be
recommended.
Frequency
This parameter lets you set the cutoff frequency of the multimode filter. The audible effect of
this is determined by the Type parameter. Both early signals and late (reverb tail) signals can be
controlled individually.
Bandwidth
This parameter lets you set the bandwidth of a multimode filter. Bandwidth is specified in
octaves or fractions thereof. This parameter is available only when it has an effect (bandpass
and notch modes). In all other cases, it is hidden. Both early signals and late (reverb tail) signals
can be controlled individually.
Shelf
This parameter effects all filter types. The shelf specifies the audio level below which the filter
has no effect. For example, let’s imagine we’re using a one-pole lowpass with shelf set at -12
dB. The lowpass filter affects only the strongest 12 dB of the signal. Below the shelf, the signal
is unfiltered. This is easy to understand by viewing the EQ window.
Type
This parameter selects what type of filter is used for shaping the tone of the effect. The
selectable options include: 1 Pole Lopass, 1 Pole Hipass, 2 Pole Lopass, 2 Pole Hipass,
bandpass, and Notch. Both early signals and late (reverb tail) signals can be controlled
individually.
