Pre-Delay
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.
Hi Frequency Cut
Hi Frequency Cut controls the decay character-
istic of the high frequency components of the
reverb. 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).
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).
