REVERSE REVERB EFFECT
Time domain response of a reverse reverb,
impulse input. Reverb effect is digitally
reversed to produce the opposite sound
pattern of natural (or digital) reverb.
Time domain response of a gated reverb,
impulse input. Reverb "tail" is digitally cut off
just past its peak.
GATED REVERB
DELAY TIME
Time domain response of a slapback effect,
impulse input. Secondary signal is a
reproduction of the original input signal
(similar amplitude).
DELAY WITH REGEN
FIXED PERCENTAGE OF
ATTENUATION EACH
DELAY TIME
Time domain response of a delay effect,
impulse input. Secondary signals are
reproductions of the original signal, diminishing
in amplitude over a fixed time period.
Time domain response of a typical reverb,
impulse input. Early reflections and reverb
"tail" combined with room characteristics
determine the sound of the effect.
MULTITAP
DELAY TIME
IN OUT
Time domain response of a multi-tap effect,
impulse input. Secondary signals are
reproductions of the original signal, differing in
amplitude, at nearly the same time.
