PREECHO LEVEL
Preechoes can best be understood by visualizing a
stage where the early reflections are the sounds ema-
nating from the rear and side stage walls directly after
the sound from the stage. Usually the rear stage wall
reflection is earlier and louder than those from the two
side walls. The preechoes are actually clusters of
echoes, with the density of the cluster set by DIFFU-
SION.
The preecho reflection parameters change the per-
ceived locations of reflecting surfaces surrounding the
source. PREECHO LEVEL adjusts the loudness of the
reflection.
Note: Some of the presets use an algorithm with
six preechoes, and others only have two. If you
need more than two when creating a sound, be
sure to start with a preset that has six.

PREECHO DELAY TIME
For each of the PREECHO LEVEL parameters, there
is a corresponding PREECHO DELAY TIME parame-
ter. PREECHO DELAY TIME sets the delay time in ms
for one of the preechoes. PREECHO DELAY TIME is
not affected by PREDELAY, so preechoes can be
placed to occur before the reverberation starts.
