REVERB (DECAY) TIME

Time domain response of a typical reverb, impulse input. Early reflections and reverb "tail" combined with room characteristics determine the sound of the effect.

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.

GATED 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 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 multi-tap effect, impulse input. Secondary signals are reproductions of the original signal, differing in amplitude, at nearly the same time.
