Fans of 'The X Factor' have accused the programme makers of using technology to make some contestants’ voices sound better.
The Press Association reports that viewers lodged their disapproval by taking to internet forums, including the show's own forums, to complain about the use of "autotuning" during the show which returned to ITV on Saturday night.
The majority of comment centred about the performance of teenager Gamu Nhengu who sang the Katrina and the Waves’ song 'Walking on Sunshine'.
Judge Simon Cowell said the 18-year-old from Clackmannanshire, Scotland was "really talented" before she was unanimously voted through to the next round.
But some viewers went online to accuse the producers of using autotune - used in studios to improve performances by correcting pitch and disguising off-key mistakes.
Comments were also made about G and S singer Caroline, who also made it through to round two.
A spokesman for The X Factor said post-production work was necessary due to the number of microphones used during filming. "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."
