"There's a whole lot of people who put a Sabine in the rack, live.   I think Digitech are doing them as well. I was listening to canned music in Wickes the builder's merchant the other day and there were some horrifying off-harmonies in the recording being played. Lesser of two evils, it seems to me."

For me, I'd always rather hear a bum note than the weird, jarring, alienating quality that auto-tune lends to a vocal.

The best (worst) example of auto-tune is in the programme Glee. If you're not sure what we're talking about in this thread, just watch an episode of that programme and pay attention to the timbre of the voices.

It's a weird sensation, hearing an auto-tuned voice - it adds a glissando quality to the singing, and just an ever-so-slightly tinny quality to the sound, though tinny isn't quite the right word. It's a bit like suddenly noticing that there's actually a pane of glass in the really nice view you were just looking at.
