The producers of 'The X Factor' have admitted that post-production work was carried out on some of the vocals heard during the first audition show.

The revelation comes after viewers complained that they thought some of Saturday night's contestants had been auto-tuned.

We received hundreds of comments on our TV blog following the programme, with many unhappy about what they had heard on the show.

Yahoo! TV user Benatcamp said: "Autotune was used on either live mics or post production. So obvious and so, so pointless!!! I (have) already complained to ITV!"

Meanwhile, Bingo.Jesus added: "A triumph for Autotune. You could hear Gamu's voice glitching all over the place. And the girl from G & S. They turned it on for her, off for him. Do they think we're deaf?"

An ‘X Factor’ spokesperson responded to viewers' complaints, claiming that post-production work was necessary due to the number of microphones used during the auditions.

In a statement, they said: "The judges make their decisions at the auditions stage based on what they hear on the day, live in the arena. The footage and sound is then edited and dubbed into a finished programme, to deliver the most entertaining experience possible for viewers.

"When it gets to the live shows, it will be all live."

So the judges decisions were based on the real singing and not the autotuned version, which is good to here, perhaps they will remove it for the next show
