EFFECTS SECTION
Stereo Flanger
A flanger consists of a short audio delay line whose output is mixed together
with the original signal. Mixing the delayed and original signals together results
in multiple frequency cancellations creating a comb filter effect as shown in the
diagram below. Since the flanger is a type of filter, it works best with harmoni-
cally rich sounds such as strings.
The flanging effect was originally created using two tape recorders playing
identical recordings. By exactly synchronizing the two decks and then slowing
the speed of one by grasping the tape reel flanges, the flanging effect was born.
The flanger in the UltraProteus is a stereo device consisting of two separate
delay lines controlled by a single set of controls. The block diagram of the
flanger is shown below.
