Chorus
Chorus reproduces the sound of multiple instruments play-
ing in unison for a thicker, deeper tone. As all instruments
differ slightly from each other in terms of pitch and phase,
their playing together produces an overall sound that is
warmer and more spacious. In order to reproduce this type
of behavior, chorus effects make use of delay. Specifically, a
delayed, second version of the original signal is produced
and given a vibrato-type effect by varying its delay time over
a period of approximately one second using an LFO. When
this second version is mixed back into the original signal,
the resulting tone sounds as if multiple instruments are
being played in unison.
Tremolo & Rotary
Tremolo effects are characterized by the way in which they
modulate volume in a cyclical fashion. An auto-pan effect,
meanwhile, moves the sound from left to right in a similar
cyclical manner, and a rotary speaker effect simulates the
distinctive vibrato of rotary-type speakers often used with
organs. In a rotary speaker, the horn and rotor are spun in
order to create highly unique sounds using the Doppler
Effect.
Delay
Delay effects create a delayed version of the input signal,
and as such, they can be used for many different purposes,
such as creating a sense of spaciousness or thickening a
sound.
