This is from the statement saying sound filters will no longer be used.
"We do not use, and never have used, audio technology that would unfairly reflect any singer's original performance on The X Factor," a spokeswoman said.
"In line with standard television practice, sound processing filters are used to remove background noise on our pre-recorded shows."
This is a blatant lie. Anyone with any experience at all of audio processing knows that auto-tune and noise removal are totally different. Noise removal leaves no artefacts if done correctly. You might lose a bit of top end but that's it. If overused it can produce a strange warbling which sounds nothing like auto-tune.
So, they've decided to remove the noise removal filters??
They must think the public are idiots. Yep, X Factor producers think the public are idiots shocker!
