Meaning of CHORUS in English

CHORUS

A special effect in which a single sound source is made to sound like several, through the use of time delay and detuning. Delaying the input by a slowly varying time between 15 and35 milliseconds and mixing the dry input signal back in, a wavy, multiple-voice effect is achieved. It's also possible to feed a portion of the signal back into the input.
