This is one of the simplest descriptions of “how auto-tune works” I’ve found!
Told in the form of a cheesy auto-tuned song with software like Logic Pro X and Melodyne featured. I’d be curious to know what you’re using to auto-tune?
I’m using Automatic Pitch Correction in Adobe Audition and also love Waves Tune.
I think that sometimes the singer is not used to perform with headphones, the feeling of the sound it’s different. In some cases a good singer at stage can sound totally different at the studio. I’m not telling that everyone but this is a common side effect at recording sometimes.
