Chapter 29: D-Verb 157
D-Verb Decay Control
Decay controls the rate at which the reverb de-
cays after the original direct signal stops. The
value of the Decay setting is affected by the Size
and Algorithm controls. This control can be set
to infinity on most algorithms for infinite re-
verb times.
D-Verb Pre-Delay Control
Pre-Delay determines the amount of time that
elapses between the original audio event and the
onset of reverberation. Under natural condi-
tions, the amount of pre-delay depends on the
size and construction of the acoustic space, and
the relative position of the sound source and the
listener. Pre-Delay attempts to duplicate this
phenomenon and is used to create a sense of dis-
tance and volume within an acoustic space. Long
Pre-Delay settings place the reverberant field
behind rather than on top of the original audio
signal.
D-Verb Hi Frequency Cut
Hi Frequency Cut controls the decay character-
istic of the high frequency components of the re-
verb. It acts in conjunction with the Low Pass
Filter control to create the overall high fre-
quency contour of the reverb. When set rela-
tively low, high frequencies decay more quickly
than low frequencies, simulating the effect of air
absorption in a hall. The maximum value of this
control is Off (which effectively means bypass).
D-Verb Low Pass Filter
Low Pass Filter controls the overall high fre-
quency content of the reverb by setting the fre-
quency above which a 6 dB per octave filter at-
tenuates the processed signal. The maximum
value of this control is Off (which effectively
means bypass).
