The chorus effect was originally designed to make a single person's voice sound like multiple voices saying or singing the same thing, i.e. make a soloist into a chorus. It has since become a common effect used with musical instruments as well.

The effect is a type of delay — the original signal is duplicated and played at varying lengths and pitches. This creates the effect of multiple sources, as each source is very slightly out of time and tune (just as in real life). Technically, a chorus is similar to a flanger.

Common parameters include:

Number of Voices: The number of times the source is multiplied.
Delay: The minimum delay length, typically 20 to 30 milliseconds.
Sweep Depth/ Width: The maximum delay length.

The following example is the chorus settings window in Adobe Audition.
