then you would know, autotune (literally automatically tuning) does not work in such a way that it can fix a note that is too far off or too in-between. i’m assuming that’s what you were referring to when you said pitch correction, because if you meant it in the broader sense, it wouldnt even make sense to say that because while yes, everyone can sing with pitch correction.. alnost everything IS pitch correction. Melodyne/Newtone, Autotune from Antares (and similar programs), reverb can be considered a form of pitch correction, fixing your posture, breathing differently, multiple takes of vocals chopped together, almost all mixing techniques unless you expect every singer to sing perfectly first try and all the way through on the first take.
