On another ocassion I had to adjust some female voice, and prefeered WavesTune results/ease of use over Melodine DNA. Of the three, I found Autotune EVO gave me MUCH better result when fine-tuning some Whistleing on a Western track. I've been toying with WavesTune, Melodyne DNA and Autotune Evo over the last few years. That along with everything I've seen and read on the forums tells me it must be pretty good. I've never had or used Melodyne but all my friend that have it swear by it. However, I only use it to fix vocals that are just a little off. That's all I've used on the Win7 computer and never had a problem with it.
ReaTune actually works pretty well too in the manual mode. However, once I got it working it really worked pretty well. The biggest problem I had with it was just getting it set up with the keycodes so that I could use it, which kind of left a bad taste in my mouth for Antares.
I started with Autotune back when it came on 3 or 4 5-1/4" floppies. I will keep playing around with it to give it a fair shot. I have heard a lot about Melodyne being better, but it's not working for me at least not at the moment.
Have recently tried Reatune and so far I am actually impressed with basic tuning in manual mode. Started on Autotune 15 years ago and wondering what everyone thinks is the best today? I have tried Melodyne a little, but have a problem with fine tuning passing tones unlike autotune being able to draw a line longer or shorter to effect or not the passing tones in a phrase.
