Berita Tren Hari Ini: Apple developing hi-tech 'iKaraoke' app that lets wannabe pop stars know when they are off-key

Fast approaching a staggering 500,000 apps, you'd be forgiven for thinking the Apple iPhone allows us to do almost anything.

But designers are now patenting technology to help achieve the impossible for many - the ability to sing perfectly.

Apple has produced software for the iPhone and iPod turning the devices into a mobile karaoke system that tells you clearly if you are off-key or miss a beat.

Patent: Apple's proposed software to turn the iPhone and iPod into mobile karaoke systems that tell you if you are off key or miss a beat

How it will look: Like a traditional karaoke machine with an Apple twist

The user will be able to use their iTunes library to choose their favourite songs to sing along to.

On the screen, just like a karaoke machine, the lyrics and tune will run along it in time with music.

But in a bid to improve the person's performance the software will analyse singing throughout and let them know how they are doing, with any mistakes amplified and the perfect pitch made to sound even better.

It is understood that through the user's earphones their errors will be made to sound worse so they can clearly hear where to improve.

But a great singer will hear their performance as if it was at a venue like the Royal Albert Hall.

At the end of the song every person will get a full appraisal of what they did right and wrong.

The patent also proposes allowing users to record their performances and edit them later, while a digital readout would also allow them to see how they had performed compared to the original.
