Time domain response of a typical reverb,
impulse input. Early reflections and reverb
"tail" combined with room characteristics
determine the sound of the effect.
Time domain response of a gated reverb,
impulse input. Reverb "tail" is digitally cut off
just past its peak.
Time domain response of a delay effect,
