Chorus

Note: This article was initially imported from Wikipedia.

In music technology, chorus is an effect caused by taking an audio signal and mixing it with several delayed copies of itself and/or several pitch-shifted copies of itself. The resulting sound simulates the sound of several instruments or voices where there is really only one. Stereo chorus produces the same effect, but the chorus effect varies between the left and right channels.

Chorus can be achieved either by hardware or plugins.
