I came across this article from Hometracked.com.
Pitch correction software has applications from restoration and mix-rescue to outright distortion of a voice or instrument. I’ll discuss some of the more tasteful uses of these auto-tune tools (whether the original from Antares, or a variant like the free GSnap) below. But first I thought I’d highlight their misuse to illustrate the effects we usually try to avoid.
I think the second example on the page is more of a vocoder thing, ala Gorillaz or Peter Gabriel. However, there is a band I play in where we are trying to do a CD, so, we hired someone to record us live. After 3 months, he had two songs done, and I’d say they are not anything to write home about. He even put in clapping which makes it sound even more fake.
When I record, I try NOT to do much to it. Balance it, sure, but pitch correction…..not really, unless there is something that totally sticks out like a sore thumb. I had a two or three songs that students did before Christmas that I had to do some pitch correction with, but it was not the whole song. Just a couple of notes here and there.
