REVERB
Also called “reverberation,” this refers to the sound energy
remaining in a room or closed space after the original
sound stops. Similar to yet different from echo, reverb is
the indirect, diffuse sound of reflections from the walls and
ceiling that accompany the direct sound. The characteris-
tics of this indirect sound depends on the size of the room
or space and the materials and furnishings in the room.
Reverb Effect types use digital signal processing to simu-
late these characteristics.
■
CHORUS
Depending on the particular chorus type and parameters,
this can make a voice sound “larger,” as if several identical
instruments were playing in unison, or it can give a voice
greater warmth and depth.
■
TREMOLO & ROTARY
The tremolo effect cyclically modulates the volume. The
Rotary Speaker effect simulates the characteristic vibrato
effect of a rotary speaker.
■
DELAY
An effect (or device) that delays an audio signal for ambi-
ent or rhythmic effects.
