Is Auto-Tune easy to use?
While it can create a robotic, high-pitched voice, it also can regulate traditional singing voices and make them pitch perfect. If you want to use autotune to edit the sound of a track, you can do so fairly easily.
How is Auto-Tune used today?
Auto-Tune can also be used as an effect to distort the human voice when pitch is raised or lowered significantly, such that the voice is heard to leap from note to note stepwise, like a synthesizer. Auto-Tune has become standard equipment in professional recording studios.
