Is Michael Bublé auto-tuned

Answer 1

In general, no, he is not auto-tuned. Certainly his studio recordings use very little if any auto-tuning; it's a fairly honest sound with bags of jazz-hall reverb. If there's any auto-tuning involved it is extremely subtle. There are occasional chorus effects which might be confused with auto-tuning, but nothing that could ever be confused with the more extreme auto-tuning that is now known as the Cher effect.

However, Michael Bublé has certainly used some extreme auto-tuning, whether or not he was actually aware of it. See An Audience With MichaelBubléduring his rendition of Cry Me A River. The Cher Effect is clearly audible here. However, such an extreme effect would prove more than a little distracting to any performer (especially as the studio version didn't use any auto-tune) so it's unlikely Michael would have been aware he was being tuned. It's possible the auto-tuning occurred during post-production, but if that were the case the engineer should rightly hang his head in shame; it's nothing short of abysmal. It seems more likely the effect was added during the live recording but was not relayed to Michael. Either way, it is unlikely Michael would have had any say in the matter. TV executives tend to be a law unto themselves on that regard.
