Susan Boyle fans around the world may be surprised to hear that the star’s début performance on “Britain’s Got Talent” was digitally tweaked.

Earlier this week the Simon Cowell’s UK show “The X-Factor” admitted using technology to improve contestants singing during the audition stages. It has since emerged that the very same technology is employed by Cowell’s other reality show “Britain’s Got Talent.”

A spokeswoman for Talkback Thames, producer of both shows, said: “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.”

Susan Boyle, a Scottish singer shot to fame with her rendition of “I Dreamed a Dream” from Les Misérables in April 2009, when she was a contestant on the reality show. Susan became an instant You Tube & Internet sensation and wowed audiences throughout the world. Later that year the star released her first album “I Dreamed a Dream,” which became an instant bestseller.
