DELAY ALGORITHMS

Note:
See the parameter glossary that begins
on page 8 for delay algorithm parameter
descriptions. See pages 23 to 27 for
delay algorithm diagrams.

SIMPLE DELAYS

Simple Delays are basic delay algorithms that
feature one delay line for each input channel.
(During 5-channel operation, the center input
channel is split between the left and right
input channels.) Each delay line has a
single output, called a "voice." Each voice has
independent delay time (up to 4 seconds),
output level, feedback control, filtering, and
panning. The feedback path includes diffusion,
as well as highpass and lowpass filters. In
addition to this basic voice architecture,
Simple Delays also feature diffusion control for
diffusors in the input and feedback paths.
Simple Delays are available in stereo, quad,
and 5-channel DSP configurations.

DUAL DELAYS

Dual Delays are similar to Simple Delays,
except Dual Delays feature two delay lines for
each input channel. Each delay line has a single
output or "voice." Each voice has independent
delay time (up to 2 seconds), output level,
feedback control, filtering, and panning.
The feedback path includes highpass and
lowpass filters. In addition to this basic voice
architecture, Dual Delays feature parameters
that provide expanded diffusion controls.

RANDOM DELAYS

Random Delays provide no-holds-barred control
over delays. These algorithms feature one delay
line per input channel. (During 5-channel
operation, the center channel is split between
the left and right channels.) Each delay line
has three outputs, called "voices." Each voice
has independent delay time (up to 3 seconds,
plus an additional second provided by the
randomizers described in the next paragraph),
output level, feedback control, filtering, and
panning. Random Delays have the same
diffusion controls as Dual Delays.
In addition to this basic voice architecture,
Random Delays feature two randomizers that
provide up to one second of additional delay
time for each voice. Voices can be assigned to
either randomizer, or to no randomizer at
all. See the Rand1 and Rand2 parameter
descriptions on page 9 for more information.
Random Delays are similar to Simple Delays,
but are especially useful for:
• Multitap Tape Loops
Feedback can be used to recirculate
delays. Appropriate use of highpass and
lowpass filters emulates the bandpass
effects of multi-generational tape loops
(hiss not included). Feedback diffusion
allows emulation of azimuth misalignment
– a hallmark of the sound.
• Early Reflection Modeling
Although different in scope from Lexicon
Ambience algorithms, Random Delays can
be used to place early reflections in stereo
or surround fields. The Rand1 and Rand2
parameters, which control randomization,
can be used to prevent coloration that
might otherwise occur with straight
delays.
