The Parameters
The seven plug-in reverbs contain hundreds of presets, covering just about every possible need.
But you can refine and customize any preset by adjusting its parameters. Parameters are the
building blocks within each preset that determine how it sounds and behaves.
Each algorithm contains a set of parameters, and a variety of those parameters are combined to
create a preset.
Below are all the algorithm parameters you can edit in the PCM Native Plug-ins. Note that
sometimes parameter names are abbreviated when they appear onscreen, and they may have
prefixes indicating what channel they control (for example, Level may appear as RightInLvl).
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.
Bass Boost (Room)
This parameter is closely tied to the Bass Crossover parameter. It controls the boost (or cut) of
signal below that crossover.
Depending on the type of impulse response selected, the listener may become aware of an
excess or insufficiency of low frequency output. This parameter may be used to correct the
frequency response.
!
NOTE: Though the term “impulse” is used in this manual, these algorithms are NOT
convolution reverbs!
BassRT
This parameter controls bass reverb time. It is closely associated with the Bass Crossover and
Reverb Time parameters. BassRT is a multiple of Reverb Time that applies to signal below the
frequency described by Bass Crossover. If BassRT is less than 1.0, then the low frequency part of
the reverb tail will be shorter than the midrange part. If BassRT is greater than 1.0, then the low
frequency part of the tail is longer.
