Was Susan Boyle auto-tuned on Britain's Got Talent audition?
Susan Boyle Boyle, 49, shocked the world with her audition for the British talent show last year but there are now claims that auto-tuning software could have been used to make her sound even better.
Simon Cowell's ITV show The X Factor recently started a row when it admitted to using auto-tuning technology to cover up faults in auditionees' voices on its show.
A source said to UK newspaper Evening Standard: The exact same techniques are used on Britain's Got Talent as on The X Factor - it's the same production team. The sounds are cleaned up - it's an open secret and an industry standard.
"This goes for everyone - even Susan Boyle's audition was smoothed out in post-production to give it the best possible sound."
A spokeswoman for Talkback Thames, which produces both shows, added: "In line with standard television practice, sound filtering technology has been used on Britain's Got Talent on our pre-recorded shows, but this does not unfairly reflect any singer's performance.
"The performance shown on screen is a fair reflection of performance given in the live theatre. Judges make their decision based on that live performance."
