Like the rest of the Christians in America I was watching Disney's 2014 Night of Joy concert. It was even trending on twitter. I was pretty sure the artists were using autotune during parts of their concerts because well it was just too good compared with the beginning. I thought I could hear some echo ghosting or something. I don't know if I caught it on the two recordings I made.
I'm not throwing stones but I'd rather hear them as they sound with a few bad notes and stuff.
How can I tell from a specific recording if the artist(s) have used autotune or not?
