I was interested to see that this thread had already exploded out to five pages since I last saw it, but to be honest this entire thread up to this point was incredibly boring to read...all just rehashed rehashed Auto-Tune debating that had basically nothing to do with Joey's original post.
Joey, first of all I'm not entirely understanding everything about your question. Are you getting complaints just from random fans/music listeners/people on the internet? Or are you getting complaints from inside the bands you're working with? Considering that there is such an extreme majority of music these days that's Auto-Tuned without any kind of flame-war about it, it's weird to me that you're getting picked on. I would assume that it's mostly internet folk who pick on you for "over-Auto-Tuning", but if they're the same internet folk who pick on everyone else's Auto-Tuning, then it's obvious that you have nothing to worry about. However, if you are absolutely sure that the people who rag on you every day about Auto-Tune do
not also rag on other commercial releases, then there's something you're doing wrong/different that's making your Auto-Tuning more obvious than everyone else's. I'm not incredibly familiar with your work, but everything that I
have heard sounds great, and although the singing parts I've heard sound "perfect", I haven't heard anything yet that sounded overdone with the tuning. That For The Fallen Dreams rough mix you put up had a singing part towards the end of the song, and listening to it again right now, those vocals sound great to me. I don't know how intensely you're tuning things, but my own approach (which is not unique to me) has always been to use the graphic mode (set to the default retune level), hand draw the notes, and don't draw the beginnings and endings of notes too perfectly. If the singer took a little bit too long to level out near the pitch he was aiming for, then don't go in there and draw a really intense/strong beginning...leave a bit of the trail-up, or at least draw a line that's more gradual. It's always been obvious to me when you're pushing the tuner too hard... If it sounds awful without drawing something drastically different than the singer actually sang, then you should have spent more time during tracking. Otherwise, I've always been able to make Auto-Tuning undetectable when I want to be.
I also spent a day at the studio with
Aaron Sprinkle back in 2004 (before I had really discovered my love for audio engineering), and the entire day he was just tuning Hawk Nelson vocals. I didn't pay close attention to what he was doing really, I mostly just sat in the room and discussed different recording-related topics with him, but he was definitely using Antares Auto-Tune, and I remember him telling me that he hand draws all the notes (no line tool), and actually prefers that the lines have a bit of imperfection to them, as to him it sounded more realistic. I mean, if you think about it, deviating slightly from an absolutely
perfect line wouldn't likely be perceived by the human ear as "out of tune", so as long as it sounds "in-tune", then why push something so far that it actually starts to sound fake and synth-like? I know that the "retune" control on Auto-Tune basically tells the software how closely to tune the notes to the lines you've drawn (the highest being exactly on the lines you've drawn, the lowest probably just barely nudging the notes so that it doesn't even create an audible change), which sounds like the same concept of hand-drawing or using the line-tool, but if Aaron Sprinkle is right, then there is also some value to avoiding the line tool.
I realize that you've probably spent more time tuning vocals than I have, so you probably know everything I've already just typed (especially software controls and functionality), but hopefully there's some kind of helpful thought in there for you!
