According to Paul McCartney, artificial intelligence has been used to extract John Lennon’s voice from an old demo to create “the last Beatles record.”

He told the BBC that the technology was used to separate the Beatles’ voices from background sounds during the making of director Peter Jackson’s 2021 documentary series, “The Beatles: Get Back.”

McCartney says that they were:

“able to extricate John’s voice from a ropey little bit of cassette and a piano… He could separate them with AI, he’d tell the machine ‘That’s a voice, this is a guitar, lose the guitar… So when we came to make what will be the last Beatles record, it was a demo that John had that we worked on… We were able to take John’s voice and get it pure through this AI so then we could mix the record as you would do. It gives you some sort of leeway.”
