Hall reverb
The hall reverb simulates the response of a real concert hall adding a sense of space to
the source material with less initial density than a chamber reverb. The slower build up
of reflections and generally longer decay times associated with this type of algorithm
allows for increased clarity of the source, while offering a richer more lush overall sound
that is less dense in character.
This effect features contour controls to adjust the envelope shape during the initial
portion of the reverb tail and also the time over which the reflection density increases.
Reflective surface materials and air absorption properties can be simulated by adjusting
the high and low frequency cut amount and high frequency damping. Low frequency
decay and cross-over parameters allow relative control over the low band reverb tail
length. This can be used to either simulate real room responses, which often have a
longer decay time at low frequencies or alternatively can be useful to reduce low
frequency energy in a live environment where it may already be present due to the
natural reverberation of the venue.
12 diffusion control
knob
Increases the density of both the early reflections and
reverb tail, between 0 and 100%.
13 decay control
knob
Adjusts the decay time relative to the room size, from
minimum to maximum.
14 size control knob Specifies the room size (also affects decay), from
small to large.
15 pre delay control
knob
Specifies the time before the reverb begins, between
0ms and 200ms.
16 In switch Switches the Plate Reverb effect in/out.
