The chorus effect (or ``choralizer'') is any signal processor which makes one sound source (such as a voice) sound like many such sources singing (or playing) in unison. Since performance in unison is never exact, chorus effects simulate this by making independently modified copies of the input signal. Modifications may include (1) delay, (2) frequency shift, and (3) amplitude modulation.
